How are you finding the 35 IS? I hope I didn't talk it up too much
I honestly don't use it.. I knew that going in 35mm was not a 'prime' focal length for me, I spend most of my time shooting wide angle with the 24L. I also picked up the 24L/50L/85L within the span on a few weeks, so the 35IS was more of an afterthought, I just picked it up due to the great price.
From the limited use it's really good, just not one I reach for that often. Though, I was walking home today from the train and shooting a bit and I had the 50ZE on the A7R and was feeling a bit constrained.. Normally I pack the 24L and 50ZE, but had a heavy laptop load in the other bag so just took the 50. I might turn it into a work-commute lens for a bit and swap it out with the 24L and see how it goes.
