The result of using extension tubes is that the distance from the back of the lens to the film surface is longer, which means you can take photographs at shorter distances to the subject. Extension tubes are thus commonly used for macro photography and sometimes for closeup portraits.

When using the camera's TTL metering system, no exposure compensation will be required (exposure compensation is required for handheld meters).

This updated version II is now also fully compatible with Canon Digital EF-S lenses, as well as standard photo EF and TS-E lenses.

Extension Tube EF 12 II is especially suited for close-focusing with wide-angle lenses. Compatible with all lenses, except 15mm f/2.8 fisheye, 14mm f/2.8L and MP-E 65mm f/2.8.

Q: 1. Hey folks so here's my question: I have this lens that I ordered for my 5D mark III. I didnt LOVE it as I always felt a bit claustrophobic shooting. I just felt like I wanted to back up all the time. So I don't use it often.Anyway, I see that the specs for the newer STM version of this lens, say Standard prime 50mm lens is designed for use on full-frame EOS DSLR, however can also be used with APS-C-sized sensors where it will provide an 80mm equivalent focal length. Does that mean that the lens I already have (Canon EF 50mm f/1.8 II Lens) also looks like 80mm on a camera? I ask because that's the look I want, and I just planned on finally using this lens I never use on my 60D and having it look like 80mm. Just wanted to make sure I have it right...

A: Using an APS-C sensor just crops the image in the camera because the sensor is smaller. You can crop a full-frame image taken with the 50 mm lens and get the same effect. You will reduce the image area by 1.6 squared or about 2.5 times, which is how much smaller the APS-C size sensor is. A 25 megapeixel full-sized image becomes about 10 Mp. So the look you get is a reduced field of view, not an enlarged image. If you use the 50 mm lens on your APS-C camera, the camera crops the image for you. But your APS-C camera probably has more megapixels than 10, so you get a higher resolution image, but not a magnified one. You can't get higher focal length by cropping your pictures, just a reduced field of view. By the way, the effect you want seems to be a reduced field of view, which kind of contradicts your earlier statement that the 50mm lens on the full frame camera felt claustrophobic, even though it has a wider field of view than the APS-C setup would have..

Q: 5. I have a minolta maxxum 600si (film camera). If I got a lens adapter for my canon 50mm 1.8, would I be able to shoot on my film camera with this lens?

A: If you can adapt Canon EF to the minolta camera, there is no question that you could USE IT, but since there is no APERTURE ring on this lens, you'd be shooting all the time on f/22 I THINK. A better bet would be to buy an adapter to mount NIKON F lenses to a Minolta mount. You can get old, fast, film era lenses with aperture rings fairly cheaply from Nikon. In fact for the coatings alone, I guess I would buy old Nikon AF lenses, since they retain the aperture ring but offer better coatings. But the reason for the old Nikon F lenses (AI and AI-S types) is for the excellent BUILD quality. Modern AF lenses are SO LOOSE in the focus ring to keep the load on the camera's focus motor to a minimum, that they are really sloppy and loose. The old film lenses generally have silky smooth focus rings with longer throws that make for more accurate focusing.

Q: 6. is this lens compatible with the Canon 500D?
