FA 31/1.8 Vs FA 35/2 Vs DAL 35/2.4 Shootout (Two Picture Sets)

See: http://pentax.org.pl/viewtopic.php?p=765767

(or Google-translated English Page Here)

All posted images are 100% crops of the original photos, which were taken with a K-7. For (much) easier viewing and for better measurbation, I've tabulated the results as below. Just click to open each of the full crops in a new window/tab:-

Aperture (f-number)
FA 31mm F1.8 Limited
FA 35mm F2
DA(L) 35mm F2.4
1.8

2.5/2.4

I have two quick observations from the above:-

1. The FA31 Limited has the worst focusing accuracy. It has a great tendency of out focusing at larger apertures but yet at 2.4 and beyond, the focusing errors can still be seen;

2. The FA35 particularly has a cooler tone than the other two.

You take now for other findings! Just feel free to give your inputs by writing a comment here, to this Blog entry, if you really have some to add. :-)
