Only thing wrong with this statement is the Fact I have never suggested that you shoot at F11. Never not ever … in fact my lens rarely if ever moves off of F6.3 wide open and never fails to get sharp shots …does that throw a spanner in the works hmmmmmmmIN reply to Alby, Jeff and Robin,
Yes, I understand what you are saying but in response there's a few things I'd like to say (if I can remember them......) :
Weight of the lens is an issue for me and the Zuiko is about 5 oz heavier, also longer and wider.
I had the Zuiko lens long enough to try it out (I've still actually got it) and was able to send some files to the Olympus techie. He/they examined them and came to the conclusion that I need to send my EM1.2 for checking/repair. He wouldn't suggest that the lens needed checking because it was brand new and I was getting +/- the same problems as with the Panny. he couldn't say for sure that it wasn't a "settings" problem. Perhaps I should press him a bit further on this?
Apparently the Zuiko lens was designed by Sigma so in some ways it isn't an "Olympus" lens.
Following your instructions, Jeff, I changed the settings in my EM1.2. I still got some bum results with the Panny lens, but there was one set which may be a clue to what the problem is. While I was sitting near a peregrine eyrie a juvenile came and perched in a tree right in front of me. It sat there for about 5 minutes. So I was able to take some pictures in a very relaxed and non-hurried situation. The first few were at 1/320 second and f11. (ISO 1000) and they were pretty sharp. At least good enough to put them through DXOLab and get an excellent result, enabling me to crop down well into the file and still get a sharp image. Then I changed to 1/1250 sec at f5.8 and it was back to the old mushy mess. This suggests that :
1. The IS is working well with my current settings as recommended by Jeff. 1/320 @ f11 at 318 mm - it has to be working well!
2. Something is not right at wider apertures.
3. It's all well and good knowing that but won't help me with birds in flight or in lower light conditions..
Some people have posted images using the Panny lens which are absolutely brilliant!
The EM1.2 is still under guarantee thanks to HDEW; I just hope it will be possible to get hold of a OM1 at a reasonable price in the next few months!
There's no reason why I shouldn't get the Zuiko lens some time in the future if I need to.
So it's all still a work in progress, decisions are still to be made but I'm starting to get there. Thanks for taking the time to comment on my problems!
