A 200mm zoom would,give me greater framing opportunities when out doing landscapes, is nice to capture a more relaxed picture when doing street, and allows me a bit of leeway when trying to take wildlife shots. I see it very much as an extension to general propose lens set rather than a specialist long telephoto that dedicated birders and wildlife photographers use. If I want to go longer then I’d go with scoping these days because decent dedicated telephoto lenses are shockingly expensive.
I’d probably go with a f2.8 70-200 zoom if I was going to get a longer lens for the Nikon. I know from experience that 200mm is ok handheld for sensible ISO and the 64000 ISO and in lens stabilisation with the Nikon set up I could shoot some really grainy but stable low light shots. But that lens is a BIG chunk of glass and carrying that around with the f2.8 24-70 and 14-35 it’s a major weight. Lovely pics though
Obviously with the Oly 4:3 I’d get more bang for my grams, but it’s a smaller sensor and daft as it sounds the cameras are physically just a bit small in my hands for comfortable handling. Again, good pics.
If I decided to,go with the 4:3 system, I’d want a decent 24-70 equivalent lens as well and probably another body. I’ve got a Pen F which is a fantastic carry around camera, especially with the 17mm pancake lens, and the f2 70mm is a superb portrait lens if you’ve got enough room. But the 24-70 on the Nikon is the one I’d take out for a landscape session and the 14-35 lets me go wider when I need to.
Pixel count isn’t really an issue these days, the 36Mpix on the full frame and 24Mpix on the 4:3 are plenty enough and if I did change my system, then getting a similar pixel density isn’t going to push me into exotic territory. And to be honest computational sensors are only going to improve and proliferate.
It’s an interesting subject because there’s as much emotional investment in the decision as there is technical consideration. It’s one ive been pondering for a year or two now, and with technology marching ever onward, I very time I come back to it, I have to do a lot of extra research to catch up again.
