Designed for 24-hour operation the Tamron 12VM412ASIR uses infrared corrected lens elements to produce brighter images in lighting conditions ranging from ambient to totally dark locations and is compatible with both Day/Night and conventional B/W cameras. Using special multi-layer lens coating, this vari-focal lens provides corner-to-corner image quality and compensates for glare and ghosting caused by back-lit environments.

              Comments about Tamron 12VM412ASIR 1/2" 4-12mm F/1.2 Infrared Manual C-Mount Lens:

              I used this lens with a my Panasonic GH2 Micro four Thirds camera via a Cmount to m43 adapter. I used a think adapter made by Kipon so I didnt need to modify anything. You have to use ETC mode or it will vignette severely. But in ETC mode there is none. The 2 best uses for it are really wide angle shots and macro shots. I was very impressed with the macro abilities of the lens. You can literally touch the lens and it'll still be in focus. The one down side is that when you zoom all the way in, you loose infinity focus. You can really only get things about 6 feet in front of you to focus properly. But if you're not zoomed all the way in, you can get everything in focus fine. So you do loose a little bit of that tele reach. Overall a great lens if you're okay with shooting in ETC mode. Just be aware that in ETC mode artifacts like grain show up more easily in low light.

                Comments about Tamron 12VM412ASIR 1/2" 4-12mm F/1.2 Infrared Manual C-Mount Lens:

                Nice wide angle lens. Fast! Works great in low light. I use it on a Panasonic GH2 with a c-mount adapter. For the money, it's amazing. I shoot video, not stills with this lens. For stills, one might want to invest in a fully automatic lens. This lens is about as old school as it gets using the way I do- manual everything. Note also that is has a zoom function, but must be refocused every time you zoom in or out. Still, until I save enough for a Leica, this will work. Kind of looks silly to the client who knows gear. But if looks are not an issue, this is great! Can do amazing macro too!

                Great lens, fast and sharp, even wide open. Use with GH2 in crop mode and you get a very bright, very wide image. You'll need to custom fit an adapter. search for it on YouTube.
