What about EF-S Lenses with no manual aperture? How is it controlled?

You can control it one of two ways, first there is an iris button I. The upper left that will switch the aperture as soon as yiu press it to what it thinks is the best setting, second you can press the fast forward button or rewind button on the camera to open or close the Aperture.

It is a generic lens that comes with a T-mount for the EOS optical system but it only works in manual focus mode. I am under impressed with this lens and will probably be returning it. It is very heavy and does not seem to be very user friendly

Incorrect. This lens auto focuses!You can manually fine tune the focusing quickly with the manual focus ring if needed. "Many EF lenses are equipped with a ring-type USM which allows full-time manual focus in AF mode. This means you can manually fine-tune focusing as soon as auto focus is complete, without having to switch to manual focusing mode."-google

Some high-end lenses have focusing ring that can be pulled back into a MF only mode. If this is the case simply push the focus ring forward. Otherwise, press the AF button (above the on/off switch) and use the left and right direction buttons until S-AF is selected.

No auto focus control, even if you're using lenses with AF. (At least for the canon lens mount, though I expect all the mounts are like this). Also, iris/exposure control is limited on some lenses. Check their website to see what works.

The EF-S Canon Lens is designed for the APS size censor cameras. It is my understanding that you at wide angle you would see dark corners, etc. I also think Canon designed the camera mounts such that an EF-S Lens will not attach to a full frame mount camera.

Yes.. your camera uses the EF and EFS lens.... practice your manual operation of your camera to get the best results... Happy Shooting

There is no electronic interface between lens and camera body when using the adapter so you need to shoot in manual mode to control aperture and shutter speed.

Hi, unfortunately Canon has created a new mirrorless lens mount standard (http://en.wikipedia.org/wiki/Canon_EF-M_lens_mount). They produce an adapter for the EF mount standard which works best with EF-S lenses (x1) and ok with EF lenses (x1.6 due to the sensor size). If by "F mount" you FD mount then you could try buying an EF-M to EF/EF-S mount and buy and FD to EF lens adaptor (search for "fd to ef lens adaptor" on amazon) then use them together. I have not tried this and would interested in the results.Cheers,JP

I don't know but I don't think that you can do anything but manually focus with these lens babies... they are not designed to autofocus so there is a bit of a learning and experimenting with them till you get the look that you want....each aperture ring gives you a slightly different look... so you have to know where to direct your focus.. and that has to be done manually....

Nope. The "S" in "EF-S" tells you it's for APSC cameras only not full frame. It's for SL-1, The Rebels, 7D, and the XXd series like the 70D. The STM version of this lens is very nice, quite sharp. Its silent operation is what you want for video.

I only use manual lenses with my E-620 and it works great. I use Nikon, Oly and Ziess lenses with adapters. You need to set the camera setting to MF, set the dial to M for manual controls. The E620 happily provides metering support for manual lenses regardless of Make. You would need to adjust the aperture manually on the lens and the Shutter Speed from the camera dial. Of course, you have to focus using the manual ring on the lens as well. That's it.

You will be able to mount your lenses, but you won't get autofocus or aperture control. They will essential be manual focus, fixed aperture lenses, so you will only be able to shoot them wide open. If you have a Canon body you can "trick" the lenses into stopping down before you mount them using the DOF preview button.

The lens has only electric drive for the focusing. You can use it only when it is powered by the body. I have a very simple extension tubes without any electrical connection and when I attaching this lens manual focus is not working

I use a Tamron pro 1.4 extender. Ability to use extender depends on the lens. Most of the EF-S lenses cannot mount on a converter. I use the extender with a 80-200L f4 lens. It will not auto focus on a f 5.6 lens. Hope this helps

These lens are compatible with EF-S and not with EF. It won't work on FF cameras like 1D as the size is small.

Indeed you can, the electronic pass-through works perfectly well even when stacked, so EF and EF-S lenses still retail full functionality for auto-focus.With that said, I would like to add that even though the pass-through works, and auto-focus still functions, the camera has a hard time focusing at that close of a range and I recommend using manual focus. Either way, your exif information on the photos will still show the proper lens setup, but does NOT include any information about the EF 12 or EF 25 attachments. :)
