Sooo I think I’ve eventually decided to give the 85GM a try. I’ve always previously owned an 85 and find I like shooting 35/85 (and 135 when I feel like carrying all 3). Been going round in circles with the 85GM vs the sigma 85 DG DN for months now and almost bought the sigma this week but I had a think today about what is most important to me and got to the conclusion that it’s the rendering above all else and the GM wins in that regard. I find that I take my most pleasing shots when it’s a lens with good rendering ahead of sharpness etc. I purchased the 135GM trying to find the 135L magic I miss so much but if I’m honest with myself the 135GM simply doesn’t have it. It’s great in so many other ways, and I do love it, but just doesn’t do what the 135L does.
So thinking I should try the 85GM and see if the focus speed is actually an issue or not for what I shoot and if it is good then I will consider selling the 135. If it’s not I’ll likely sell it and try the sigma. That’s the plan anyway, will see how it pans out when something else catches my eye 



I may have to look into a tracker someday.
