Q: 3. What do you mean by middle and tele zoom settings..because I have a 18-135 and a canon 60d ..

A: Hi.As you know, extensions tube are used to be able to focus closer than the minimum admited by the lens, at the cost of loosing the focus to infinite when the tube is in place.As well, as the lens goes further away from its natural position, there will be vigneting with wide angle lenses. This is to be noticed in not so wide angle lenses with full frame.That's why its use is not recommended for lenses wider than around 50 mm. On your Canon 60D probably you'll be able to go wider, but I don't know how much, as I only use full frame bodies.I hope this helps youJavier

Q: 4. I own a set of Matthew's C Stands #756140 which I bought over 10 years ago. These stands have a base with a quick release pin for the legs. Do these stands also have a quick release pin? If not, does Matthew's still make a model with a quick release pin?

Q: 6. I have a Canon 7D, and Canon Macro Lens EF 100mm 1:28 USM. From what I have been reading the Extension Tube EF 12 II will work with my setup, correct? Auto focus will work correct? Will I gain or lose depth of field using this tube on my setup?

A: Yes it will fit your 7D. Autofocus will work. Depth of field will be reduced somewhat.

Q: 7. If I use this with the canon 100mm 2.8L lens, how much more will improve the .99’ focus distance? I ask because I read somewhere that this doesn’t allow you to focus closer but instead improves magnification.

A: An extension tube allows you to focus closer than the stated lenses minimum focus distance as well as increases the macro magnification of the subject by the size of the extension tube divided by the lens focal length.

Q: 8. Looking to use this with my 1dx mark ii on my 85mm 1.4 IS for doing closeup macro like shots for product videos instead of spending $750 on the 100mm macro lens for the moment (i'll eventually get it). Anyone else have sucess using it for anything similar?

A: Adding this extension tube between the 1dx2 and the 85mm 1.4 IS will change the magnification from 0.12 to 0.41. It will help you take photos of items such as a large flower, but a very small item like a diamond on a ring would need a higher magnification of 1x. If the products you are taking videos of are large enough such as a desert plate this extension tube will work for that.
