    Awesome for the price

    I suspect this is identical to the , but I couldn't find that at the time, and this one is cheaper anyway. I'd be interested to know if they are different.Performance is very similar to the . Sharpness is maybe a little bit better off-center (this is NOT based on any kind of objective test, just first subjective impression). Vignetting is worse, more like the .

    Reasonable manual lens for great price

    Update: Lens seller contacted me and very politely asked to consider giving a better review. So I added one star (truth in reviewing). The reason that I upgraded my rating is that my initial reaction was on the tail of having played with $300-$500 lenses. Not really fair. My update thus includes that fact that for less than 5-10x the price of a mainstream lens you get a lens that has some unique characteristics that might be useful in many types of photography.The lens is well-made, metal lens barrel & hardware, comes with end caps, and has coated lenses. For $26 dollars the lens is a good deal DEPENDING on your expectations. Having spent more time with it, I believe these are probably made for automated visual inspections. Focus and F are manually controlled and continuous (no click stops). There is a filter thread that appears to be 37mm BUT a standard 37mm filter does not fit - it would be nice, if this were a standard thread.Limitations:This lens... 4/5 beikokunotora (Dallas, TX United States) - See all my reviews Enthusiast: Photography Verified Purchase(What's this?)

    SURPRISING

    4/5 gracies mom - See all my reviews Verified Purchase(What's this?) This review is from: SainSonic 50mm f/1.4 CCTV Cine Lens (Camera) This is a little gem and really surprised me with the quality of the pics I could capture.I wish there was a fish eye and a wide angle version in this price range.Takes some time to play with so you know how to cull all the good points but worth it.Totally manual and in some cases a little it or miss but brings the sense of fun and adventure back into photographyfor me.Have the 25 and find this , though a more narrow field of vision to be the better of the two for my purposes.
