I need something shorter than my 35-100 zoom. Occasionally as I still do most shoots with 35-100, 45mm and 75mm. I shoot portrait only, so there is nothing else. Natural light 90% of the time. I consider: 14mm for its size and price. But may be too dark and too wide 17mm just as I like 35mm on FF. Hear some negative reviews 25mm as I had one and like it. Nothing bad except its close to my 35mm zoom. As an alternative I can take: 12-35 to cover all range + good friend to my 35-100. The issue is that I will not use it a lot. Would be this zoom IQ close to primes above? I need AF. Lets imagine, what would you take? And what would be your choose if money is not a factor.
