I can't understand your adoration for the 100-200, considering my OP and Kasson's link to his review.
I don't adore the lens but I do like it very much.
I respect the tests and don't deny them, but I just don't see the problems at the long end when I pixel peep my images. Maybe I have a really good copy, or maybe I'm just engaging n some subconscious wishhul thinking..... But to me the lens is really good for what it is and I was always amazed by it on the 50r and now with the GFX 100 I think it is very sharp.
I could be wrong and maybe it is just a matter of degrees of quality. Jim said it was a good lens for the price.
I need 100-200, so maybe I'm just happy we have that zoom for GFX.
I will say that when I'm traveling with my GFX gear (which is always now), I rarely take the 250. Yet when I have a shot at 200 with the 100-200, I always say to myself, "Man I wish I had brought the 250."
You know I had the 70-200 L lenses (F4 and 2.8) for years and shot them on the 5D cameras. Jow I look at those images and they can't hold a candle to the GFX with 100-200. But that is just a subjective and very general opinion. It is certainly not scientific. Just an impression.
Hey Jim ... you said the 100-200 is better on the short end. I read an article the other day that says all zooms are better at the wide end abd it explained the optical science of why that is so. Is that true? Have you reviewed or know of any zooms that are better at the long end then the short end? Just curious in terms of general photography knowledge.
