I recently saw and "felt" the Fuji's 16-55 and 50-140. One needs to use the battery grip for balance. I did not do an exact size/weight comparison but I guess it's pretty close to a DSLR setup. I can see the need for fast, pro-grade zoom lenses for wedding photography, etc. but it made me think why a pro (or anyone else) would accept the performance disadvantage of mirrorless (primarily AF-speed, refresh rate) to shoot with Fuji (I will leave the FF vs APS-C debate aside). Is it the retro-feeling? Is it the possibility to set ISO, shutter speed and aperture via external controls? Personally I decided to stick to the primes to be able to travel light and select 3 lenses to bring with me depending on the purpose. The upcoming 140-400 and 120mm lenses (that I really want) made me think again why I should not switch to Nikon Df/750 (D810 is too big for my taste), 24mm, 50/58mm, 135mm and 300mm lenses and keep the X100T as a "pocket" camera. I like the FF-look in certain situations better, it handles considerably faster (I swapped cameras with someone and we both agreed), and I bet it does not weigh much more, if one selects the lenses carefully. Is it indeed nostalgia? investment protection? Or are these 2.8 zooms work horses for assignments, enabling the photographer to travel light when needed? I am curious what your current thoughts are!
