Makmut - my understanding of the physics of optics is that a faster 100-500 would have to also be
larger (diameter). That means it will be both heavier and a lot more expensive. When I got the R5m2
I didn't understand how much importance the extra dynamic range of the sensor would be. As in -
the R5m2 made my RF 100-500 better. Perhaps "better glass" might mean "better tech in the body"?
How many birders would opt for a R6 I/II over the R7? How many will opt for a R6 III or wait for the R7 II? I am in the wait crowd, as my current travel combo now is the R1 & R5 II.
Have been using the R6 ii over the R7 ever since i purchased an R6ii in mid December of 2023.
It easily outperforms the R7 in every way. In addition to its stellar low light performance. Still mulling over replacing the R7, likely selling to a friend for a straight grand, but could also use it towards store credit towards an R6iii which I'll likely pick up more than the R7 or even an R5 ii with those tempting 45 megapixels.
Am I the only one who doesn't understand the "hype" about the Sony 4,5/100-400?
The EF 4,5-5,6 100-400 cost half, was lighter and at longer focals about 1/2 aperture slower...
The Sony is certainly a brillant lens, but I still don't get it.
The advantages (IMO) are: 1) internal zoom, 2) ⅔ stop faster at 400 mm, 3) with TC you can get out to 560 mm @ f6.3, 4) reasonably lightweight at ~ 4.4 lbs (with the hood). In contrast, my Canon RF 100-300 mm f2.8 with 2x TC (600 mm f5.6) weighs in at almost 7 lbs. Ideally, for me I would love to have a RF 100-400 mm f4.5 DO with 1.4x TC built in with a weight of less than 5 lbs. One can always dream.
Any rumors to complete the f2.8 stm trinity? A light 50-150 or even a 70-150 would be a perfect complement to a wide angle(i use the 14-35mm and 20mm but i miss something between that and my 100-500mm)
I agree that sonys 100-400 seem like a good compromise between a 100-400/500 and a more exotic 100-300

Disadvantages, compared to the "old" EF:
-Weight (+300g)
-Price (X 2,5...)
-Size (longer, wider)
-It's a Sony
Advantages: internal zoom, 2/3 opener
Sorry, but I still don't get the excitement.
