    Amazing!!

    I have to say that I was not expecting much with this product - I mean, a lens adapter AND a lens for little more than the price of the adapter; however, despite some of the other less positive reviews here, I found the adapter to be of good solid quality. Heavy like steel as opposed to cheaper alloys. I found that it secured to the camera firmly with a firm click of the lens lock, and the lens screwed in and tightened as expected. I did not experience any looseness, and it held up for hours during a several hour photography session. The lens performs as advertised and provides surprisingly sharp images. The iris functions correctly, it is easy to step up and down with the f/stops, and it has a smooth manual focus.It is a very fast lens, which coupled with the Sony Nex's low light capabilities, churns out dark defying night shot images can can look very surreal. With respect to video capture, it provides a very different ascetically pleasing perspective with movies that... 5/5 Paul Incommendatus - See all my reviews Verified Purchase(What's this?)

    For the price, a must-have

    If you're on a budget and you don't own a 35mm prime lens, this little lens is a must-have! It's certainly not perfect, but it's surprisingly sharp.DIMENSIONS: 2" tall, 5.5" in circumference (basically 1.75" in diameter). In other words, ultra portable! My DSLR prime lenses are like 3x bulkierIDEAL AMBIANCE: Simply because you have to manually adjust the focus, I wouldn't recommend this for shooting moving subjects. It's best suited for still photography (i.e. portraits, still life) where you have all the time in the world to fine-tune. A monopod or tripod would be beneficial. If shooting a few feet away or closer, you'd ideally only care about one specific area of the subject in focus (i.e. a few petals from a large flower). The focus ring is by no means *difficult* to operate or unsmooth, but it does require you to exert more force than say, manually focusing on an EF-S lens.BUILD QUALITY: The lens itself is VERY solid--all metal/glass except for... 5/5 tightsandtea - See all my reviews Verified Purchase(What's this?)

    Pure Fun -- HIGHLY Recommended!

    This little thing kicks butt. For thirty-odd bucks, how can you wrong?! It belongs in every NEX (& M4/3) owner's kit.Pros:- Image quality is pretty dang good and totally belies its price. Get to know the advantages and shortcomings (see "cons" below) and work with its attributes and you can achieve some pretty awesome images.- Very sharp frame center; on par with either NEX kit lens (18-55mm/16mm) if not maybe even a bit sharper.- Super-small size makes the NEX closer to being pocketable. Also available for M4/3.)- Smoothly-damped focus and aperture rings.- Comes with adapter!- Wonderfully lightweight.- FUN to use. Brings the joy back into photography.Cons:- Doesn't stay screwed on to adapter very securely, especially when toying around with the aperture ring.- Build quality is...interesting (off-center numbers, unfinished metal parts, questionable calibration, etc.). But dude, it's only thirty... 5/5 hawh - See all my reviews Verified Purchase(What's this?)

    This lens is good for Portrait Photography, but it not good for Landscape Photography. The sharpness in the center is fine, but the border is soft. It looks like a tilt lens.

    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 Verified Purchase(What's this?)

    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 .

    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.

    Great Deal

    5/5 alan - See all my reviews Verified Purchase(What's this?) This review is from: 6-15mm 1/3" F1.4 CS Mount Varifocal CCTV Manual Lens (Electronics) This lens is a great deal. With its manual zoom, focus, and aperture settings, it is perfect for the IP video camera I occasionally use to keep an eye out for visitors while I'm doing things in other places. This lens is a HUGE improvement over the fixed focal-length, fixed aperture lens that came with my video camera, and for the the price, it's a steal. It was shipped from Hong Kong, but the delivery time, considering, was surprisingly fast. Help other customers find the most helpful reviews  Was this review helpful to you? , November 28, 2012

    Don't get for APSC sized sensors or larger.

    3/5 The Cheese - See all my reviews Verified Purchase(What's this?) This review is from: 6-15mm 1/3" F1.4 CS Mount Varifocal CCTV Manual Lens (Electronics) I can't really rate this, because it doesn't work on larger sensors. I have a sony a6000 and it can only be focused up close/macro. Infinity focus is not possible on my camera. I have other c mount lenses that work on the camera, but they aren't as wide angle, which I believe is the issue.
