hi all,
i've tried CY 100/f2 and 85/1.4 on 400D canon body but find that the AE mode cannot function properly (either over or under) when aperature is down from f2.8 to f2 / f1.4.
THEN
I used M mode and adjust the aperature and shutter time by way of 測光表. I find that the image is also under when f2 and f1.4.
i think it may be the problem of the design of APS body using FF lens like CY. do you have such experience??? also anyone tried canon lens on 400D or other APS body encountering the same problem like CY lens???
Have try that with CY 50/1.4 & 35/1.4 before, you need to set exp compensation.....
