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 | Nil | Nil | |
| 2 | Nil | ||
| 2.5/2.4 | |||
| 2.8 | |||
| 4 | |||
| 1.8 | Nil | Nil | |
| 2 | Nil | ||
| 2.5/2.4 | |||
| 2.8 | |||
| 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. :-)
