I borrowed a friends Nikon lens to use with my t3i, but it has no manual aperture control, is there a way to change the f/stop?

Unfortunately not- there is no way to change aperture on this lens adapter.

I'm not familiar with that lens so I'm not sure. If you were using it on your Nikon camera, it should work. No autofocus or f-stop info though. All will be manual.

You have to take the camera out of Automatic mode. You can only use the lens in manual mode.

Hi Beth, yes, you can change the aperture settings as well as the shutter speed, ISO level and exposure compensation in Manual mode. Thanks_Mitch

Here is a REALLY obvious one. You can switch between manual and autofocus on this lense by pushing and pulling the autofocus ring in or out. It reads AF (autofocus) when pulled out, MF when pulled back in. This is distinct to Tokina, so not intuitive if you're used to other lenses. This lens autofocuses extremely well on my D7000 - it's my sharpest lens.

the "G" lenses don't have an aperture ring . f stop is selected with thumbwheel on camera

It will only work in Manual mode only. all other modes require the connection to the lens to change f-stop and ISO.

Hi Shaun! The lens has no electric functions so it can't talk to the camera like more advanced/expensive/modern lenses do. If you can continue shooting you're good to go, you'll just have to adjust your iris and focus manually, as opposed to those functions being camera controlled. Most cameras should just let you say "okay" and keep shooting though. Have fun! The lens has a really unique and beautiful flare, so make sure you check that out. Cheers, Colin.

Yes. Ring controls aperture on both newer G lens and my older AI lenses. Takes some getting used to. You'll have no f stop data displayed anywhere.

Yonnattan,Simply stated you can use the adapter in manual mode if the lens has an aperture ring as well as aperture priority if the lens has an aperture ring. I hope this answers your question. Regards Dennis Dellis

the aperture setting would have to be electronic and done with your setting on camera controls. There is not a manual setting ring on the lens. On my sony A700 I can get f3.5 to f22 by using a manual setting.

Hello, the lens is manual, works manually only. Please put your camera into "no lens attached" mode and continue to shoot manually on in Aperture priority mode.Thank you.

Yes you can adjust the aperture... It goes from f/2.8 to f/22. It's a great piece of glass!

there is no way that I am aware of to change the lens system. it is all self contained.I have had very good luck with mine as is. I hope this helps answer your question

I shoot with a Nikon that has options to trigger a remote flash. Not familiar with Canon T3i.

Hi! you can use any FD to EOS adaptors. Of course you have to set the F/stop and focus yourself. Some of these adaptors work better than others. The adaptors from Fotodiox are much better made. They cost a little more but you will get no play with the lens on the adaptor. Hint, Mount the adaptor to the lens then the whole unit to the body. Make sure you have the index marks lined correctly or they lens or the adaptor will get stuck.. A little practice any they will be as sharp as the autofocus lenses...

I haven't owned this lens for very long but I've had very good results with it so far. I mainly shoot with automatic settings and the camera adjusts the aperture for each picture of course. It is not always on f/2.8. It varies, depending on the light conditions, etc. if you shoot manually you can keep it on f/2.8 if you want. That is simply the largest aperture setting you can use on this lens. You CAN change it to a smaller aperture if you want.
