I have owned every limited, FA and DA, except the 20-40mm and 31mm (and the 31mm is in the mail
).
Here is my rundown:
DA 15mm: Great little lens. If you like to include the sun in your landscapes, this is the ultimate lens. Perfect complement for the 18-135mm, can easily fit in your pocket when you are hiking. Wide, but not "obnoxiously" so.
DA 21mm: Small enough that there isn't an excuse to ever not have it with you. But I really didn't click with the focal length. Kind of wide, but not dramatically so. Would probably be great for stitched panoramas and street shooting (nice for environmental portraiture, not my cup o' tea, but if it is yours, I would look strongly at this lens).
DA 35mm Macro: Nice and starting sharp wide open. Great versatile focal length for an APS-C camera. This is the ultimate flower lens. I sometimes wish it were a stop faster for indoor use, but of course that would make it bigger. I personally would prefer the bigger size, but cannot fault them at all for making that trade. All in all, a solid lens.
FA 43mm: Very underrated, maybe because it isn't a typical FL for APS-C lenses....but I think it adds to the charm. You get a little more intimate with your subject than with a "normal" lens. I LOVE it's rendering.
DA 70mm: Very compact. It is very sharp, but kind of a "meh" lens to me. I am not particularly enamored with its rendering.
FA 77mm: Now this is a lens whose rendering I am very enamored with
When you nail focus wide open (not necessarily easy), and you have good lighting, it can turn the most mundane subject into a work of art. Is prone to purple fringing, so watch your background. I just love this lens.
DFA 100mm Macro WR: I know, not technically a limited...but it should be
I had a Canon 100mm Macro L, and the size differential between these 2 lenses (both of which are full frame lenses) is just mind boggling. It also doubles as a great portrait lens.
No thoughts on the 31mm yet...I cant wait to get it into my grubby hands
If I could only choose 2....idk. My starting point would be 15, 31, 43, 77 and 100mm. They all perform different missions, definitely not apples-to-apples (how does one compare a wide angle to a portrait lens to a macro??)
