Sold my 135 F2 and regret it everyday
I have the 85 F1.8 but have yet to use it on my 6D, but will soon and anticipate great results as it's done beautifully on my 60D and 5D2.
As for the 100 macro, i finally picked up the L version after owning the non L for ages. It's almost terrifying how sharp it is no matter what camera you mount it to. It's definitely an awesome multipurpose lens.
As far as the 100 f2 goes...i've never had the pleasure of testing this lens but have heard great things about it and that it is a highly underrated lens.
Difficult choices are difficult. I almost feel focal length wise the 135 may give you the range you're aiming for, but my opinion is 1 and 7.5 billion. I'm sure many others on here will give you better advice
Well, I've been thinking about it a lot and I think I am going to go with the 85mm since when doing my first studio shoot the other night with my 24-105 I stuck around 85mm the whole shoot, and the 85mm will effectively become a 135(136)mm lens when used on my EOS M. That and as I said, I know almost without a doubt I want the 135L within the next couple of years. Now I'm adding another variable though since I can get the Bower (Samyang) 85mm for $250 new, which is over $100 less than the EF 85/1.8 and pretty much every review says it's a (far) better lens... idk though, I have zero issues with MF, but my 35mm is my only other AF prime so having a 2 prime combo with AF could be useful...
I've posted this question in other threads already and I know it's a dead horse... but if anyone has experience with both and can give me an honest opinion between the EF 85/1.8 and Samyang 85/1.4 that'd be awesome I'm beating my brain with this...
