I just came across a little something that has me a little perplexed.
When I take a shot with my 50-200 SWD zoomed to 200mm (as it reads on the lens scale), the photo data (on the camera screen and in the ORF file when viewed in Olympus Master 2) says the focal length is only at 158mm. The other "index" marks (50, 70, 100, and 150) seem to give the right report.
(I just noticed this as I was taking some shots this week using the 50-200 with the EC-14 and it was only reporting 224mm max for the focal length.) This happens on both my E-3 and my E-500.
I also checked my 12-60 and 35-100 by themselves, and both seem to match the index marks on the lens. The 35-100 with the EC-14 reports 141.0mm -- close enough for my taste! Certainly seems to be a lens issue -- although everything else about the lens seems fine. (Although I am a little disappointed with the focus on the 35-100 -- I will probably post some images later and ask about that one in another thread.)
I checked the contacts and everything seems to be OK there -- no crud, scratches, or bending/denting.
I have had the lens and cameras for several years. I have taken a look back at a number of shots over the years, it looks like I sometimes get 158mm reported, and sometimes 200mm.
My firmware for the E-3 is version 1.4, the E-500 is version 1.2, and the version for the lens is 1.1. Olympus Master tells me that I am running the most recent versions of each.
Any help with this issue would be appreciated!!
