David, apologies for taking your thread off topic. My recommendation for your OP is the O75-300II. For a casual long lens, it has very good IQ and is lighter and cheaper. I used it for wildlife, sports and sundry other stuff on my E-M10 with great results. My recommendation would be for you to get it and try it on your GX85 looking at ergonomics and IS. For wildlife and sports, you are looking at high shutter speeds in any case, so the IS may well be good enough. On my E-M10, I found that using the grip really improved handling for that lens.....
No need to apologize, it's just equivalency debates can often take on a life of there own.
I really think if I were to go down the 75-300 road I should swap the body. I'd probably look at the E-M10 mkII if I do. The Oly grip for then is great, I prefer tilting screens, and having owned an E-P5/E-M1 mkI/E-M5 mkII they all have more features than I really use.
This is something i have been pondering too, i think while the 400 fills every GAS nook n cranny possible it is a kilo in weight and quite large. The 100-300 with the new ois and sealing is the sensible choice for my GX8. Now i have to figure out whether i can justify the PL12-60 over my 14-45 & 14-140!
I would love to get the PL12-60 and PL50-200 f/2.8-4.0. I might someday.
.....Barry, I think that 150mm is too short unless they are shooting young kids (<10y). FWIW, I have shot my son's lacrosse games with the O40-150R and the O14-150II and found both of them lacking on the long end. No issues with S-AF or burst performance on my E-M10, though.
I have to agree 140/150 is just not enough. It's the issue I have with my 14-140, it's "just" not long enough. The 45-200 probably would be, the 45-175? Not sure.
I have done more or less what op is considering. I sold the 40-150 f2.8 two weeks ago because I never brought it along. Late last year I sold a Nikon 200-500 for the same reason. If I am bringing the big lenses, I take my Nikon DX or FX with the f2.8 trinity lenses depending on what I intend to shoot, mostly landscape, soccer (outdoor and indoor), handball (indoor) and equestrian. My low weight or vaction kit now consists of a Fujifilm X100F, which serves my focal need between 35-70, and an EM5ii with 9-18, 40-150R and 100-300 II. Another reason I picked up the X100F is the leaf shutter. I was debating whether to get the 100-300 or 100-400, but I know that the 100-400 will be used way less than the smaller 100-300. And I probably end up selling it as I did with the 40-150 f2.8, which btw is a great lense. But for my use the 40-150R suffices and I expect the 100-300 will do as well.
Yes, very similar. With the X70 I have a 28 / 35 / 50 thanks to the built in TC. I've been reasonably happy with the TC results from the 35 so far. I could also add the WCL-X70 Wide Converter for a 21mm. So my X70 paired with the GX85 & P7-14 or GX85 & P35-100 f/4-5.6 would cover a lot of situations. The thought of that has me considering selling the P14-140 and getting both the P35-100 and P45-175 along with the P20mm I was already planning on.
What I have now GX85 & X70:
P7-14mm
P12-32mm
P14-140mm (f/3.5-5.6)
O17mm (f/1.8) - just sold
O25mm (f/1.8) - for sale
P42.5mm (f/1.7
O9mm BCL
So my kit would be GX85 & X70:
P7-14mm
P12-32mm
P35-100mm (f/4.0-5.6)
P45-175mm
P20mm (f/1.7)
P42.5mm (f/1.7)
O9mm BCL
Have to decide it that's enough reach for now.
