Summary: This lens is great as all others in XF line. Auto focus has improved with latest FW but still gets lost in poor-light conditions. As portrait lens, this is a true winner. It just can't get much better than this considering price level. I use this lens also as macro lens with Raynox M-250. Perfect for flowers and small creatures. Now I need to wait for prices drop of new Fujinon primes(56, 23, 14 and 10-24) but until then, I'm very happy with this one.
Summary: First of all, I absolutely LOVE this lens for its image quality. The bokeh it produces is dreamy. The subject in focus is sharp with vivid details. Unfortunately, I can't say it's perfect (I won't bore you with too many details -- just google the lens and you will find far better reviews than a few lines on Amazon): -- it's not 1:1 macro. Bummer and I don't understand why it's so hard for Fuji to produce a true macro, since it's done by every other company out there.
Summary: Like a shallow depth of field no matter the f stop? This lens is for you. Granted there are many factors for getting a smooth creamy background but this lens, for me, seems to always give the smooth out-of-focus background. It's touted as a portrait lens but works great for landscape, cityscape, and street photography at a distance. It's a mid range prime. I like utilizing the zoom function, i.e., moving my feet. It forces one to think and pre-visualize. All good points.
Excerpt: I read a great deal about how slow the lens focuses. While not a DSLR speed demon, it was quite fast. B&H's exemplary customer support and return policy gave me the confidence to purchase it but it is a keeper. Bitingly sharp from wide open til diffraction. 2.4 may not meet some folks narrow depth of field requirements but I found it sufficient for my needs YMMV on that. Highly recommended.
