SSE 420-800mm

The Ultimaxx 420-800mm is a dirt-cheap manual telephoto lens with shockingly good macro performance and extreme reach. It's soft, slow, and completely manual, demanding a tripod and bright light. For moon shots and experimental close-ups on a budget, it's a blast. For anything else, save up for a stabilized autofocus lens.

The headline here is the macro score, and it's a genuine standout. A 96th percentile ranking means this lens resolves fine detail up close better than almost anything else we've tested in its category. The minimum focus distance of 62mm lets you fill the frame with tiny subjects from a comfortable distance, which is a rare trick for a lens that can also reach out to 800mm. The Super HD multi-coating does a decent job of controlling flare and ghosting, though you'll still want a hood in harsh backlight.

But the rest of the optical performance is a mixed bag. Sharpness at the long end is what you'd expect from a budget super-telephoto, soft and a bit dreamy wide open at f/16. You'll need to stop down even further for acceptable results, which pushes your shutter speeds into tripod-only territory. Chromatic aberration is visible along high-contrast edges, and the overall image quality falls into the middle of the pack compared to modern lenses. The push-pull zoom mechanism is functional but imprecise, and the integrated lock is essential to prevent the lens from creeping when pointed up or down.

The most direct comparison is with something like the Canon EF-S 55-250mm IS STM. The Canon is sharper, has fantastic image stabilization, and autofocus that actually works. But it tops out at 250mm. The Ultimaxx gives you over three times the reach, and with the included 2x converter, you're looking at a 1600mm field of view. The trade-off is that you'll be shooting on a tripod, manually focusing, and dealing with softer images. For a bird in a tree on a sunny day, the Ultimaxx can get the shot the Canon simply can't frame.

Against the Nikon Z DX 16-50mm or Sony E 16-50mm kit zooms, there's almost no overlap. Those are wide-to-normal zooms built for everyday shooting. The Ultimaxx is a single-purpose tool. The Viltrox Air AF 9mm is similarly a completely different beast. The only real competitor in spirit is a cheap mirror lens or an old adapted manual telephoto, but those usually lack the zoom flexibility and the bizarrely good macro capability this Ultimaxx brings to the table.

Pricing on this lens is all over the map, with a spread of over $18,000 across vendors, which is frankly hilarious for a lens that typically sells for around $70 to $100. Ignore the obvious pricing errors and focus on the real street price. For the cost of a decent UV filter, you're getting a 420-800mm lens with a teleconverter and a carrying case. The value proposition is almost impossible to beat if you understand what you're signing up for.

Compared to a first-party telephoto like the Canon EF-S 55-250mm f/4-5.6 IS STM, the Ultimaxx offers dramatically more reach but sacrifices autofocus, stabilization, and image quality. You're not buying this instead of a modern lens, you're buying it as a fun, experimental second lens for very specific tasks. At this price, it's a low-risk way to see if super-telephoto photography is even your thing before dropping four figures on a name-brand lens.

Let's be real, a 420-800mm zoom for under a hundred bucks sounds like a typo. The Ultimaxx 420-800mm f/8.3-16 is a fully manual, no-frills telephoto that promises extreme reach for Canon EF mount cameras. It's the kind of lens that makes you do a double-take on Amazon, wondering if you can actually get moon-crater shots for the price of a nice dinner. The answer is complicated, but for a very specific type of shooter, this thing is genuinely interesting.

This is not a lens for everyone. It's manual focus only, has no image stabilization, and the aperture is so slow that you'll be best friends with your tripod and the midday sun. But it's also incredibly lightweight at just 520g, covers a full-frame sensor, and comes with a T-mount adapter and even a 2x teleconverter in the box. The build is basic, but the rotating tripod mount is a thoughtful touch that makes handling this long tube a lot less awkward.

Who's it for? The backyard astronomer who wants to dabble in lunar photography. The wildlife enthusiast on a shoestring budget who's okay with a steep learning curve. It's a specialty tool that punches way above its weight class in one specific area: macro. Our database puts its close-up performance in the 96th percentile, which is frankly shocking for a super-telephoto zoom. If you can work within its many limitations, the Ultimaxx opens up a world of reach that normally costs ten to twenty times as much.

If you need to capture any kind of action, this lens is not for you. Sports, birds in flight, or even kids running around the yard will be an exercise in frustration without autofocus and stabilization. You should look at a used Canon EF-S 55-250mm IS STM or a Tamron 70-300mm with VC instead. You'll sacrifice reach, but you'll actually get the shot.

Also, if you're picky about image sharpness or plan to make large prints, the optical quality here will disappoint. The softness and chromatic aberration are noticeable, especially compared to even a budget modern zoom. This is a lens for experimentation and fun, not for pixel-peeping perfection. If sharpness is your priority, save up for a first-party telephoto prime or a higher-end zoom.

If you want to photograph the moon's craters, spy on distant birds at your feeder, or experiment with extreme macro on a zero-dollar budget, the Ultimaxx 420-800mm is a genuinely fun and capable tool. The macro performance alone is a reason to keep it in your bag for those times when you want to get weird with close-ups from a distance. Just know that you'll need a sturdy tripod, a lot of patience, and a willingness to delete a high percentage of soft shots.

For anyone who needs to reliably capture action, shoot in less than bright sunlight, or values sharpness and autofocus, this lens will be an exercise in frustration. It's not a replacement for a modern telephoto zoom. Think of it as a telescope that happens to mount to your camera. If you go in with those expectations, the Ultimaxx is a ridiculous amount of reach for the money and a lot of fun to mess around with.
