I would definitely be in the market for the 85mm f1.4L IS but not at the expense of my 100mm f2.8L Macro. That lens is great for insects on plants & distance to get enough light, plus its a super sharp 100mm regular lens. Different tools for different jobs.
Count me in! But I hope that it's not heavier than the current 85L, and priced around the Nikon/Sony rivals, filter isn't larger than 77mm 6mm filter and with reproduction ratio of 1:8 or better. Then, my 100L will be for sale.
Now THIS is exciting!!! 85mm (best focal distance ever for portraits - the 135mm), F1.4 (good enough for me), and with IS! With currently used systems for improved focus motor and build quality and improved optics, it'll smash the third party lenses! Hopefully it'll have weathersealing! me 2
Have a thorough look at the Zeiss 100 f2.0, a full stop brighter than your 100 L and does 1:2 mag ratio and is EPIC image quality. I've thought selling mine since it's manual focus only, but there is nothing good to replace it with, and when I try it "for one last time" it's just too good to get rid of.
