just want to try it out see what happens for now. 200L and the 300 2.8 II are the two best IQ lenses canon has right now and after shooting my friends 400 2.8 IS v1 I realize that I was limiting myself in sports to 300mm so I'm leaving that option open for the end of the year. I really really really want to try the 200L + 1.4xIII and compare it to the sigma 120-300 I have now. The sigma has been good to me. I want ultimate IQ now. the 200L is it.
It's all about focal length and your end desire. The 200L is too short imho for sports and using a 1.4x would only be a bandaid BUT I shoot my kids and there would be alot of times the 200L would be great... especially on stage that extra stop to get me from a 12,800 ISO down to a 6400 would really help out too.
The look you get from the 300 2.8 is similar to the 200L you just get a different FOV
Well, if i didn't have 300L and/or 135L then i may dream about 200L, also i always want to have many L as i can, even 400 and 600, but i know i can't have anything else much more by now, and i let that 200L pass in my dreams, my only dream now is to get more medium format, and this time with 100mp if possible, i think i don't need to have so many gear from Canon anymore, and if i will do definitely will not be 200L unless i let that 135L go first and something else such as 100-400 mk1 for example.
Sony took my interest these years, and i have kids grown up so i don't need many or lenses, i do have Canon 70-200 2.8 mkII, this will be a good one instead of 200L even not in same IQ class, so that i asked you if you have Canon 70-200 mkII and 300L and 135L then why you will think about 200L if you were in my place? can't do that kids photography with 135L for example? 300L is heavy, but to me, the look from 300 is better than 200L even at f2, i saw photos from 400 f2.8, it is way better than 300 at f2.8, so it is not about only how wide is the aperture, i prefer longer FL and good enough aperture than so fast wide aperture and less FL, for example i will never sacrifice 300L or even 135L just to have 85 1.2 or even 100 f1.0, bokeh so so much isn;t always the best even it is fun, but i do have 135L and i saw how incredible amazing photos out of it and i don't use the lens already.
