Summary: Purchased from Cameta Camera last month as an astrophotography lens with a T-adapter for my Fuji X-T1. Did not have super-high expectations, as 'cheap' mirror telephotos have hit-or-miss quality control - good ones are awesome for the money, bad ones, well, suck.
Summary: I actually love this lens.. The only reason I gave it 4 stars is because you have to purchase a separate T-mount adapter that doesn't come with it. I forgot to buy the T-mount so I haven't been able to use this lens yet.
Excerpt: I was looking for something small & inexpensive and easy to stuff into my camera bag, but not necessarily something my livelihood depended upon. This lens fit well into that idea. It is sharp enough, but lacks the crisp clarity / contrast I would like to see.
Summary: Excellent product, by reason cost benefit does not compare, and what is most important server in any camera. recommend. Produto excelente, pela razao custo beneficio nem se compara, e o que é mais importante server em qualquer camera. recomendo
Excerpt: You can focus if subject doesn't move, camera is on a tripod and iView with zooming in on the display is used. Even if zoomed perfectly, this lens is VERY SOFT. Manual focus on moving subjects is difficult.
Pros: Lightweight, Long focal length
Cons: Manual Focus Tricky, No Auto Focus, Poor in Low Light
Excellent quality / price. Recomended for normal light conditions

Summary: Excellent quality / price for a telephoto lens of reduced size and powerful. Although low light, this lens gives very good results in average light conditions and macro photography, supported by the flash.
