Okay guys... i'm about to pull the trigger on a new lens for my portrait work, the Canon 85 1.8. Cheap, excellent sharpness, fast... And then my boss (wife) asks me... what can this lens do that our 100 2.8 CANT do. I've done a lot of self research and i'm sold. While I would love to get the 85 1.2, that's just not in our cards and budget at this moment. I often shoot in tight places and to be able to blur the background just a smidge more (less photoshop work for me) is very attractive as to reduce our downtime, plus it will give us more wiggle room with framing not being AS tight. Now here is where I need your help guys... those who have both lenses, had both lenses, or similar lenses, what i'm looking for is kind of a side by side portrait showing the 85 at 1.8-2 and the 100 at 2.8... a nearer background 2-3 feet is ideal for this purpose... help me sell this lens to my wife... Yeah yeah i know the common answer will be to rent one and let her see, but to be honest, the nearest place i can rent a lens is a few hours away and to have one shipped out, well lets just say i'm hoping you guys can help first... Ok... Ready... Go!
