I think my Tamron 35/2.8 is very similar to Tim’s. I’m keen on the APO 35, but I’ll keep my Tamron. Its macro ability is important to me and means like Tim I can baby the APO 35 more, having a cheap, but awesome 35/2.8 also.
I think the Tamron 35/2.8 is the best bang for buck landscape lens there is. But yes it ergonomics aren’t great.
