Any chance that there is a AF confirm chip that works with the T4i/650d? From all the places I've looked everyone seems to have problems with this camera and the AF chips that work on previous modles (i.e. T3i, T2i, etc).

Hi TIA.
I had no issues at all with my EOS af confirm adapters. Theys come from big-is eBay store.
I used them on 400D, 40D, 5DMk2.
I dont know why they're would have a problem with the 650D.
Cheers.

I have a question about focus confirm chips and manual lenses.
So I have purchased a few manual focus lenses along with some mounts that have af-confirm chips on them, like the M42 and Pentacon six to canon mounts.
So my question is do focal lengths matter? Most of the adapters are programmed with 50mm f1.4, so If I use, say a 80mm CZJ, does the AF register this as a 50mm therefore giving false AF readings? |

Hi.
No problems at all in both cases :
AF confirm works for 50mm as well as 200mm, or any other fcal length.
and no issues for 500D.

I'm not sure which thread to use for this little "adventure" of mine, since it's more about my stupidity than any real DSLR issues 
Yesterday I took my good old Canon for a walk after a real long break. I started focusing on something, but the picture in the viewfinder was blurry all the time. I also noticed that the exposure indicator is blurry and hardly visible, so I assumed it could be some battery issue after a few months of not using the camera. It also crossed my mind that the veiwfinder might be failing.
I took some pictures "blindly", going for the least blurry image in the viewfinder while focusing. Back home I asked google what the problem might be and came across a thread where someone pointed out that this might occur due to the diopter adjustment being wrongly set. I never ever touched mine on either camera, since I shoot in glasses, so I didn't consider that a possible explanation at the beginning, but went to check just in case. It came out that it was exactly the reason for the issue - once turned to the right position, all was back to normal... Miraculously I still managed to get some in focus shots from the morning.
Well, I'm glad that the camera is fine, but I it was so stupid of me not to think about it in the first place. Women and electronic devices...

I changed my screen on Eos 40D and 5DMkII.

For 5D MkII, it's the Eg- series.
Very easy to change.
Canon official guide :
file:///C:/Users/FANAL/AppData/Local/Microsoft/Windows/INetCache/IE/NJZIJ4N7/CDLC_FocusingScreens_QuickGuide.pdf
Personnaly, no need for calibration.
Beware, the ebay link shows a very bad way of handling the focusing screen as it is very fragile and it's very easy to scratch it.
Screens must be held by their sides.
Don't even try to touch them.

Welcome mkopec1
Lens focal length and focal length reported to camera by AF confirm chip do not have to agree for AF system to work proper.

I see one here :
http://www.focusingscreen.com/work/5d2en.htm
http://www.focusingscreen.com/product_info.php?currency=USD&cPath=21_98&products_id=761
Maybe there is a cheaper one elsewhere.
Ask B&H if this one is ok for 5DMkII.

I can buy Ec-B locally for only 30 euros, I think I'll grind it myself.
