Latest Review Posted | SMC Pentax-FA 31mm F1.8 AL Limited First of all, I like the focal length a lot, 28mm is a bit wide and 35mm sometimes is not wide enough for me. 31mm is perfect on the FF for me.
Not razor sharp below f2, but still pretty good, perfect for portrait. Once you step down to 2.8 the sharpness jumps to a different level.
Rendering of this lens is just special,not as contrasty as the ZK 35 but the overall feeling is slightly better than the ZK .Another great thing about this lens is that it's sharp at all distant,so you can use it for landscape, street shooting and portrait, not like my M28mm f2 , which is great at close distant but not so good at infinity.
Last but not least, the bokeh. IMHO the 31mm produces the best bokeh I've seen from a wide angle lens, the transition from in focus area to OOF area is so smooth.
Cons:it's not cheap and I wish it can be a little smaller just like the 43&77, it would be great to add WR in the future.
Overall, this is probably my favorite Pentax lens. https://c5.staticflickr.com/6/5475/30709727052_9fcb7c494d_c.jpg https://c4.staticflickr.com/8/7453/27602813235_bc2c3e8a71_c.jpg https://c5.staticflickr.com/8/7732/27907072284_b0a9761095_c.jpg |
