Product Description
READ BEFORE ORDER
VERY IMPORTANT NOTES
FULL MANUAL LENS, no electric contacts→no auto focus→no image stabilization, require more exprerience with Manual Exposure.
- Must set camera to M mode(check the picture above) to use this lens, some may require to set "shutter release: no lens" ON in camera menu.
- Camera will not display the aperture value, must set manually on lens body.
No matter how good autofocus is, there are still times when manual focus is the better shooting option. When used in the right scenario, it gives a photographer more control over the photo, and in some cases, achieves effects that aren't otherwise possible in autofocus mode.
500mm F7.5 UMC MIRROR REFLEX
Lightdow 500mm F7.5 UMC is a compact reflex mirror lens suitable for wildlife and landscape photography and astrophotography. It is available for both DSLR and mirrorless cameras with Full Frame & APS-C sensors. The lens for DSLR cameras works with Canon EOS, Nikon, Sony A while the lens for mirrorless cameras works for Sony E, Fujifilm X, Nikon Z and Canon RF. For both DSLR and mirrorless, the optical construction features 7 lenses in 3 groups, providing exceptional image quality and contrast by reducing color aberration. Ultra Multi Coating (UMC) helps reducing ghosting and flare as much as possible.
This lens is a manual lens with smooth manual focusing. Due to the long focal length, it is recommended to focus with live-view to achieve accurate focus. As with all long telephoto lenses a combination of sturdy camera support, substantial tripod, good technique, fast shutter speed, use of remote, and mirror lock up are recommended to avoid camera shake to achieve the best results.
Unique Donut-shape Bokeh Effect
The short barrel adds to convenience while the unique donut-shape bokeh makes images even more attractive.

Very well built but images are terrible
The problem begins when you package a lens loose inside a box with NO support on the ends. This lens has a mirror. Then amazon ships in a paper bag. I have tried to take pictures and it is impossible to get a sharp image on this. Even infinity yields no results. Tried the moon on a star tracker and it is still blurred. Stars are blurry, Venus, etc all blurry. I have a t3i and I use various methods to sharpen and its not possible. I think the packaging and how they ship this will cause issues like this. If that mirror or internals are affected it will blur like this. This is my 2nd lens from these people that I had to return because of poor QC.

This lens works at least as well as any similar reflex lens I’ve ever tried. Many folks like it due to the unusual circular bokeh all these lenses exhibit. All the images shown in this review taken with this lens show that bokeh.
This review and *rating* is also in the context that it’s a reflex lens thus costing a tiny fraction of what a conventional Canon lens of this or any focal length would cost. Besides price, this lens had the advantage over Canon lenses of being small and lightweight – about the size and mass of a 50mm f1.4 lens. It’s a 500mm lens that I can always have with me where the hugely expensive Canon lenses of this power require a serious commitment to lug around.
That said, my test cameras for this lens were an R7 and an R6ii. Of course, I used an EF-RF adapter so I had the lens, the T2 adapter to EF and another adapter to get to the RF lens mount. If I can find a T2 in RF form, I’ll replace this to see if it improves lens performance.
My photo tests were conducted on a windy day with a very light carbon tripod. I had no weight to dampen down the wind caused vibration. Somewhat baffling, focus peaking did not work with this lens and I can’t say why. I missed focus on some shots and also had some motion blur so it’s reasonable that I’ll get better results under more favorable conditions. It was too windy and cold for me to stand out there longer.
One image is the whole scene taken with the R6ii with a 50mm lens. I drew a circle about roughly center of the image. I then changed to the 500mm lens and took the same scene with the reflex lens. I also duplicated the r6ii shot with the R7 to show the difference the APS-C sensor size had over the FF one.
Another image is of the arch’s leg. I was trying to focus on the skull but missed and got the arch leg. I illuminated that a bit to show detail.
In sum, this lens is capable of acceptable images except for the most serious use demands or moving subjects. To get the top performance a steady tripod is best although given the IBIS in today’s cameras, hand holding is possible.
The bigger issue is getting focus correct. To do this will, in my view, require the camera on a tripod and the use of Live View magnification. If I do my part, this is a very serviceable lens.
