First impressions of the High-Power 420-1600mm f/8.3 HD Manual Telephoto Zoom Lens for Sony Alpha A33, A35, A37, A55, A58, A57, A65, A77, A99, A100, A290, A330, A380, A390, A550, A560, A580, A700, A900 Digital SLR Cameras
I unpacked this lens with a mixture of curiosity and skepticism. The promise of a 420–1600mm range is eye-catching, and I was eager to test how usable that range is in real-world shooting rather than just on paper. The first thing I noticed was how specialized this tool feels — it’s built for very long reach, and it immediately changes how I plan shoots and support gear.
I handled it cautiously because long-range manual lenses often come with trade-offs. While the optics and finish seemed aimed at hobbyists and budget-conscious wildlife shooters, the physical size and manual operation made it clear I’d need stabilization and patience to get the best results.
Packaging and what I saw out of the box
The lens arrived with a few basic accessories and protective caps. I appreciated that the filter thread is 62mm, which makes finding filters straightforward for me — a small convenience that matters in the field.
I didn’t see any full electronic integration, so I assumed it was purely manual in focus and aperture control. That shaped my expectations: this is a lens that rewards planning, tripod use, and technique rather than quick, handheld shooting.

Build quality and handling
The lens feels utilitarian rather than premium, which matches its price and target audience. I noticed a sturdy barrel and reliable-feeling focus ring, but it lacks the weather-sealing and high-end materials of professional telephoto lenses.
I quickly learned that handling is a major part of the experience. This is not a lens I can comfortably handhold for extended periods; I use a solid tripod or monopod and often a gimbal head for smooth tracking. The manual focus ring is precise enough for deliberate adjustments, but tiny focus changes at extreme focal lengths require careful technique.
Mounting and physical fit on Sony A-mount cameras
Attaching the lens to my Sony A-mount camera was straightforward. The mechanical fit is secure and aligns properly with the camera’s mount pins.
I noted that metering and exposure controls on my camera remained usable — the lens doesn’t communicate autofocus signals, but the camera can still meter and record exposure metadata as usual. If you use an E-mount Sony mirrorless camera, you’ll need an adapter to keep functionality.
Weight, balance, and ergonomics in the field
The lens’s length and balance demand support. When I mounted it directly to a camera + tripod head setup, I used a tripod collar or clamp to avoid putting strain on the camera mount. I also found that a lens support or rail helped when pointing straight up or down during longer sessions.
I adjust to the ergonomics by setting the camera on a stable tripod and using live view for fine focus. This approach reduces fatigue and improves the chances of getting tack-sharp shots at long distances.
Optical performance overview
I evaluate image quality across several parameters: sharpness (center and edges), chromatic aberration, contrast, vignetting, and flare. This lens performs reasonably well in the center at shorter telephoto settings, but quality softens as I push to the extreme 1600mm equivalent.
In summary, I get usable images for wildlife and moon shots, but I approach high-resolution prints and critical sharpness demands with realistic expectations. The lens is best considered a tool to get subjects closer, not a precision scientific instrument.
Sharpness across the zoom range
At 420–800mm, I found the center sharpness acceptable for web use and moderate prints. The edges and corners are softer, especially wide open at f/8.3, so I often stop down a bit on the camera (use smaller aperture settings where available) when possible — although this changes depth of field and light requirements.
When I engage the 2x teleconverter to reach 1600mm, softness becomes more pronounced. That said, properly supported with a tripod and careful focusing, I can still produce compelling images of distant subjects.
Chromatic aberration and color rendition
I observed some chromatic aberration, particularly as contrast edges against bright backgrounds appear. This is more noticeable at longer focal lengths and in high-contrast scenarios like branches against a bright sky.
Color rendition is generally fine, and I was able to correct most CA issues in post-processing without significant quality loss. I recommend shooting RAW so you retain flexibility when correcting minor color fringing.
Contrast, flare, and coatings
Contrast stays reasonable in many lighting conditions, though bright side-light and direct sun can reduce contrast and introduce flare. Using a lens hood (if available for the barrel diameter) and careful composition helps minimize flare. Overall, the lens coatings seem adequate but not on par with premium telephoto optics.

The teleconverter: doubling reach with trade-offs
The included 2x teleconverter is the headline feature that turns 800mm into a staggering 1600mm. I enjoyed the extended reach for subjects I simply couldn’t get closer to otherwise. But my practical experience taught me that doubling reach comes with compromises.
I rely on the teleconverter for distant wildlife and lunar photography, where detail at extreme distance matters more than outright sharpness. The teleconverter inevitably reduces light, increases sensitivity to shake, and magnifies optical imperfections.
Effect on aperture and light transmission
Using the 2x converter effectively doubles the focal length while reducing the light by two stops. This means the nominal f/8.3 aperture behaves like roughly f/16.6 in terms of light gathering. I account for this by increasing ISO or slowing shutter speed, which can affect image noise and motion blur.
I always plan exposure accordingly and accept that to use the teleconverter successfully I need either bright light, higher ISOs, or very stable support.
Image quality with the converter attached
With the converter attached, I notice increased softness, pronounced chromatic aberration in some cases, and greater sensitivity to camera shake. However, I also get access to subjects that were previously unreachable, and for certain applications — bird-in-flight silhouettes, distant animals, or the moon — the reach compensates for the loss in resolution.
I recommend the teleconverter when reach is the priority and when you can use a tripod or fast shutter speeds to control movement.
Focus and operational considerations
This lens is manual focus only. That changes my workflow significantly, and I want to be clear about how that plays into real-world shooting.
I rely more heavily on live view magnification and focus peaking (if my camera supports it) to nail critical focus. When shooting birds or quickly moving subjects, I plan for slower acquisition and select moments where the subject is predictable. Manual focus trains me to be patient and precise, and it pays off in scenarios where autofocus might struggle.
Focus ring feel and precision
The focus ring is reasonably smooth and offers fine control. At extreme focal lengths, tiny rotations produce big shifts in focus, so I prefer to use small, deliberate motions and live view magnification for confirmation.
I also find it helpful to pre-focus on a spot I expect the subject to be and then wait for the action to enter that zone. That method reduces hunting and increases my hit rate.
Using focus aids: live view and focus peaking
If I want sharp images at long range, I use live view magnification and focus peaking (if available) as essential tools. These aids make manual focus far more manageable, especially when the subject is stationary or moves predictably.
I recommend getting comfortable with these camera features before taking the lens into the field for demanding subjects like small birds or fast sports.

Practical shooting scenarios and examples
I tested the lens in a variety of conditions to see where it shines and where it struggles. Below I outline the experiences I had across common use cases so you can decide how this lens aligns with your photography interests.
Wildlife and birds
For wildlife, this lens is a mixed bag. I got great results with large, slow-moving animals and perched birds, where the extra reach allowed intimate framing without disturbance. I used a sturdy tripod and patience, and the lens delivered images that conveyed presence and context.
For small, fast-moving birds, the manual focus and slower response made tracking difficult. If your bird photography relies on fast action and autofocus, this might not be your best tool. But for distant subjects you can approach slowly, it’s a game-changer.
Sports and distant action
At competitions where I couldn’t get close to the field, the lens gave me new framing options from the stands. The trade-off was again focus speed: I had to anticipate motion and rely on burst shooting while keeping the focus zone steady.
I found it most useful for static or semi-static action: field goal kicks, distant athletes, or moments when I could predict where the subject would be.
Landscapes and distant detail
For landscapes where I wanted to isolate distant features — rock formations, ridgelines, or mountain peaks — the lens allowed me to compress perspective and draw detail from far-away elements. Sharpness and contrast are better at the short end of the range, so I often kept to 420–800mm for scenic shots.
Using the teleconverter for landscape detail can work, but you’ll need bright light and a tripod to get the best results.
Astrophotography and moon shots
The teleconverter and long focal lengths are particularly fun for lunar photography. I captured detailed moon shots where craters and surface texture were visible. I used a tripod, mirror lockup (where available), and relatively high shutter speeds to avoid motion blur from the Earth’s rotation.
For deep-sky astrophotography (nebulae, galaxies), the lens’s aperture and manual focus make it less ideal. But for the moon, planets, and bright satellites, it’s very capable.
Low-light performance and exposure strategy
Because the maximum aperture is f/8.3, this lens is not a low-light specialist. I plan accordingly and accept that I will often need higher ISO values or slower shutter speeds.
In daylight, bright conditions, and golden hour, I can get strong results without pushing ISO too high. For dawn/dusk wildlife, I often boost ISO to 800–3200 depending on motion and my camera’s noise performance. I find that modern cameras handle higher ISOs well enough to compensate for the smaller aperture.
Recommended settings for common situations
I keep a few go-to settings in mind:
- Moon (with teleconverter): ISO 100–400, 1/125–1/250s, f/8.3 (adjust to taste)
- Stationary wildlife (tripod): ISO 100–400, 1/250–1/500s, f/8.3–f/11
- Fast wildlife or birds in flight (if possible): ISO 800–3200, 1/1000s or faster, f/8.3 (anticipate some softness)
- Landscape compression from distance: ISO 100–200, 1/125–1/500s, f/8.3–f/11
I adapt these to light conditions and use exposure compensation when necessary. Shooting RAW makes post-processing much easier, especially when correcting exposure and sharpening.

Distortion, vignetting, and post-processing needs
I noticed some vignetting at the extreme telephoto end, particularly when using the converter. Distortion is not a major issue for telephoto lenses of this type, because the field of view is narrow, but I still check images for any unusual stretching or elongation.
Post-processing plays an important role in getting the results I want. I routinely:
- Correct chromatic aberration in RAW conversion
- Apply targeted sharpening to the center and mid-areas
- Crop and adjust perspective minimally for composition
These steps help compensate for some of the optical compromises and produce pleasing final images.
Noise and sharpening trade-offs
When I raise ISO to account for the teleconverter and smaller aperture, noise becomes a factor. I use noise reduction selectively and balance it with sharpening to avoid overly soft or plasticky output. On high-ISO images, I prioritize maintaining fine detail around the subject and smoothing noise in backgrounds.
Tripod, supports, and accessories I recommend
A strong tripod and an appropriate head are essential for making this lens usable. I can’t overstate how much better my images became when I used a high-quality tripod and a gimbal or ball head with a lens collar.
I also recommend:
- A remote shutter release or camera timer to avoid shake
- Raw shooting and calibration charts if you plan serious critical work
- A lens hood or DIY solutions to reduce flare
- 62mm filters for ND or polarizers for landscape work (if you use them with care and know how they affect the image)
I keep a small cleaning kit and microfiber cloth with me because dust and smudges become noticeable at long focal lengths.
Compatibility and camera integration
This lens is specified for Sony A-mount DSLRs, and I used it on that platform without complication. The camera still meters, and I can use exposure compensation as usual.
If you own a modern Sony E-mount mirrorless camera, an adapter will let you mount the lens, but expect the same manual focus experience and test your chosen adapter for reliable fit and infinity focus accuracy.
Using it on mirrorless bodies with adapters
I used an adapter briefly and found that while fitment worked, handling changed slightly due to balance. The biggest advantage of mirrorless is live view and focus magnification, so combining this lens with an E-mount body and adapter can improve my focusing workflow. Just be careful with the adapter quality and any potential focus shift.
Pros and cons — my balanced take
I like to summarize strengths and weaknesses so I can make clear recommendations to myself and others. Here’s how I break it down.
Pros
- Incredible reach with 420–1600mm range when using the 2x teleconverter, which opens up framing possibilities I couldn’t achieve otherwise.
- Compatible with a broad range of Sony A-mount DSLRs, making it accessible for many users.
- Manual focus ring is usable and allows precise control when combined with live view.
- 62mm filter thread simplifies accessory selection.
I appreciate that this lens democratizes extreme telephoto photography for enthusiasts without deep pockets.
Cons
- Manual focus only, which limits action shooting and requires patience and skill.
- Reduced light transmission when using the 2x converter (effective aperture drops), requiring higher ISO or slower shutter speeds.
- Softness and chromatic aberration at the long end, especially at 1600mm.
- Requires solid tripod support and adds bulk to my kit.
These cons don’t disqualify the lens; they simply clarify the use cases where it’s most effective.
Who I think this lens is for
I recommend this lens to hobbyists and photographers who prioritize reach and are comfortable with manual focus. If you photograph distant wildlife, the moon, or isolated landscape features and don’t require razor-sharp corner-to-corner resolution, this lens will excite you.
I do not recommend it to fast-action sports shooters who rely on autofocus, or to photographers who demand the absolute best optical performance for large, critical prints. For those users, a high-end telephoto with autofocus and larger apertures would be a better fit.
Alternatives and comparisons
When deciding whether to keep this lens, I weighed it against alternatives:
- Mid-range supertelephotos with autofocus (often heavier and pricier) — better for fast action and critical sharpness.
- Prime supertelephotos (e.g., 600mm primes) — better optics but much more expensive.
- Telephoto adapters or cropping from high-megapixel bodies — less optical quality loss but may lack the reach.
I chose this lens when reach and budget were prioritized over absolute optical perfection.
Tips and tricks from my experience
I like practical tips I can apply immediately in the field, so here are the methods that improved my results quickly.
- Use live view and focus magnification for precise focusing.
- Pre-focus on a zone where you expect the subject to appear instead of continuously trying to track.
- Always mount on a solid tripod and use a release cable or timer to minimize vibration.
- Shoot RAW and plan to correct chromatic aberration and sharpen selectively in post.
- When using the 2x converter, accept higher ISO and faster shutter speed trade-offs to freeze motion.
These adjustments made my frustrating moments into productive sessions far more often.
Final verdict
I see this lens as a specialized creative tool. I enjoy the ability to reach 1600mm with the included teleconverter, and the lens delivered memorable images in the right conditions. Its limitations — manual focus, loss of light with the teleconverter, and reduced sharpness at extreme reach — are real but manageable with the right technique.
If I want to photograph distant subjects and I’m prepared to invest in stabilization and post-processing, this lens lets me get shots I wouldn’t otherwise attempt. It’s not a one-size-fits-all optic, but for the right photographer it’s a fun and useful addition to a kit.
Final recommendations for buyers
If you’re considering this lens, ask yourself these questions:
- Do I have a tripod and head capable of supporting long lenses?
- Am I comfortable with manual focus, or am I willing to learn and practice?
- Do I prioritize reach over speed and absolute edge-to-edge sharpness?
If you answered yes to these, I think you’ll get a lot of creative mileage out of the High-Power 420-1600mm f/8.3 HD Manual Telephoto Zoom Lens for Sony Alpha A33, A35, A37, A55, A58, A57, A65, A77, A99, A100, A290, A330, A380, A390, A550, A560, A580, A700, A900 Digital SLR Cameras. I kept mine as a specialist lens and used it for specific shoots where reach was the only way to get the image I wanted. With patience and the right setup, it’s a surprisingly capable piece of glass for its category.
