So I've been out today with the Olly test and wow equipment I'd reserved (EM1-II, 300mm f4, 40-150mm f2.8 + 1.4 TC) and I have to say I'm impressed, more so than I thought. With both lenses AF-C was noticeably better than my D850 and Tamron 150-600mm, and so is IQ. Now I know we're not comparing apples with apples here and I've been using two pro lenses today vs my 'budget' super tele zoom lens, but I was skeptical that the Olympus would even be as good on either account. I've got to say that 300mm f4 is one hell of a lens, I wish I could afford one. The 40-150mm f2.8 almost felt cheap in comparison (it doesn't feel cheap at all obviously as it's a cracking lens, but the 300mm is THAT good imo).
The only two annoying things with the EM1-II is that you can't review images until the buffer has cleared (which takes a long time) and I found this very annoying, and also that it doesn't appear to be able to store AF point by orientation. This is a feature I find extremely useful as I chop and change between portrait and landscape orientation and would like the AF point to 'save' in each orientation.
I'll got loads of photos to sift through (got a bit carried away trying out the 10fps and seeing if I could fill the buffer
) but will hopefully post some images in the next couple of days.
