Hey Guys, I lately purchases an old (over 15 years) 70-200mm 2.8 L, the glass is perfect with no scratches but I was concerned after a shooting that I had that I couldn't get sharp pictures (Little blurry) and I don't know if it's cause by the weight and the shakes or does the aging affect the lens quality.
So I know it's been a while, but did you ever test it on a tripod? I am 72 and been a photographer since age 13, but now I much prefer lenses with IS. I can hand hold my 7D (crop sensor) EF 24-105 IS STM down to 1/20 sec in dim light and ISO 3200. When I pick up my 50mm it looks so shakey in the viewfinder. LOL
Yes I did, Now I strongly believe it's a calibration issue
