Gosh, Steve, IBIS? a 50/1.2 with literally ten times the resolution of the previous model? The R5's ability to nail focus on humans to birds? Or just another several stops of DR and ISO speed improvement?
I'll meet you half-way. I like shooting landscapes and cityscapes and want maximum detail in my shots and don't need AF or IBIS to do those, just a tripod. And I'd LOVE 100MP, but I wonder if the lenses for the camera line mentioned can actually resolve that finely? The Canon 50/1.2 can, I believe. If not, then we get a high-resolution photo of a poorly focused detail, and that's not compelling to me.
I have very little use for a 50mm prime. I think I have used my f/1.4 on one occasion since I got the 6D2, when I knew I’d be taking a picture of a small group in available light. If I take anything in that focal length range, my kit zoom works fine otherwise. All my pictures of humans or birds appear sharp. One guy in the small group shot appeared slightly fuzzy because he was a bit farther away than others. The cure for that would have been to stop down slightly more, not having the camera focus on somebody else’s eye or focusing on one of his eyes and making everybody else fuzzy. As it was, when I resized for use in the neighborhood newsletter and for the web, he didn’t look fuzzy, at least not so anybody would notice.
All the things you list are nice, and I am happy they are available for people who want or need them. I have not perceived the need. Hence the lack of temptation. I am thinking of my own picture taking, which is not the same as that of a lot of folks here, apparently.
The reviews I have seen of the Fuji GX lenses tend to rave about them, some more so than others, but all really good. I would do more reading up before I decided on the two lenses I would buy, with usefulness for what I want to do the main concern. The kinds of things I would shoot with the 100S would not need IBIS or fast autofocus or birds’ eyes, just a tripod and some patience, not much unlike you.
Yesterday may be instructive. Yesterday was beautiful. The 7.8 acres of woods behind my house are looking very nice now with increasing fall colors. It has been a very busy weekend, so when I got home after lunch yesterday, I was bushed and just sat down and dozed off rather than taking the camera out into the woods. If I had had another $10,000+ of gear, I still would have sat down and dozed off. I think Wednesday will still be nice, so maybe that will be a good day to go out and shoot pictures with what I have now. If lunch with a friend tomorrow doesn’t go on too long, I could start scoping out a trail in the afternoon. I’ll put the battery on to charge tonight, just in case.
The moral of all that is that if I don’t go out to shoot over the next couple days or if it turns out to be not that much fun, then I can reasonably conclude that I’m not really that interested in expanding my landscape photography, and the temptation for that equipment will be significantly attenuated. OTOH, if my reaction is “Gee, I wish I had another 75 megapixels for this great shot,” my credit card could take a good hit before Friday.
