Right, I need some help. I currently have a Nikon D850 and various decent lenses. I also have an Olympus EM1 mk2 and a couple of decent lenses. I also have a sore back, bad eyes and am (unusually) getting older. The Nikon is perfect in almost every way, but a trip out the other day with a Sigma 150-600, 70-200 f2.8 and an 24-120 was exhausting. The only 'complaint' that I have about the D850 body is that to adjust the exposure compensation I need to press a button and twiddle a knob. Not a biggie really. The Olympus was bought as a holiday camera with a 14-150 travel lens, but I've added a 12-40 pro and a 40-150 pro with T/C to the list. I need something longer if I'm going to keep it, and so far the Panasonic 100-400 seems to be the only option. Size wise it is amazing, but I struggle with the complexity and hate having to pull out my glasses to read the menu every time I want to change things. However, I love that exposure compensation is so easy via a twiddly knob, but am just not getting on with it as much as I'd hoped. I popped into a camera shop yesterday and had a quick look at a Fuji XT2 and XH1, which both have proper knobs to twiddle, and along with the Fuji lenses they seem to be some sort of ideal compromise between the Nikon and Olympus physically. The Sony A7iii doesn't look like it'll weigh in at much less than the Nikon once a few lenses are added, and I do like the idea of a bit more reach that an APS-C sensor (that the Fuji's have) could offer, as I do find even my 150-600 is a little short at times. The XT2 has knobs for everything so looks ideal in many ways, but the XH1 has built in stabilization - not sure if that matters too much as most of the lenses I might buy have it built in, but it felt better in my hand than the XT2 as it is slightly bigger. Battery life might mean a grip will be needed on either.. As far as lenses are concerned, I use zooms almost without exception. I guess my question is what other makes should I be looking at that are fairly simple to use, as in loads of knobs rather than loads of menus and weigh in at noticeably less than the Nikon ? Also, if anyone has gone from either a D850 or a EM1mk2 to something in between I'd love to hear what and why... Many thanks in advance !
