FA31ltd wide open pics please

Hi everybody,
can the owners of FA31ltd post some examples of f1.8 here?
The reason I ask is that frequently I don't get what I'd like to get (in terms of sharpness) if I'm shooting f1.8 on distances bigger than 1-1.5m. Now I'd just like to see if I expect too much, or it's my bad focusing techinque, or it's my lens...
thank you

I find that my 31mm back focusses a bit on AF, but I use a split prism focus screen and always switch to manual focus with the 31mm.

Here is one at f1.8

thank you.
My copy seems to be ok in terms of AF precision but at bigger distances- above 2m - the images appear rather soft if shot at wider than f2.8

Hmmm, I started looking at my photos taken at f/1.8 and realized that I really don't use the 31 much for distances over 1.5 meters. Because of my "style," where I like to have one item as the subject, almost everything far away was taken with a much longer lens ("much longer" for me meaning 77mm).

I did have these:

(Taken in a locker room with one (!) overhead fluorescent light, handheld at some ungodly ISO):


You can see the light bleeding through here, although I think I actually upped the highlights in post-processing (I liked the effect). Another taken handheld @ 1/15 and ISO 800:


I am more impressed with the 31's performance within that 1.5 meter range, I think, but then I really have few photos beyond to compare to the MANY within the range.

This one is part of a series of the Bonn subway, but I like the color in this one the best. 31mm was just perfect for the composition I wanted. Handheld at 1/125 and ISO 400:


I think I'm more impressed with the 31's performance within the 1.5 meter range, but then I have so many more photos within that range that it's really not a fair comparison.

Almost: I used the FA 31, the FA 43, the FA 70, and the D-FA 100 Macro. I was/am pretty good friends with the bride, and I told her in no uncertain terms that I wasn't comfortable using flash and that I wanted to experiment with things during the shoot. She was really laid-back and agreeable, so I went with it. Generally I hate shooting weddings and the idea that you *have* to get certain shots.

I think all my 31ltd shots in my flickr set were wide open (exif is available just in case). All available in high res for pixel peeping pleasure.

This one in particular was shot wide open and quite close - in full view you can see the tiny details in the focus zone

i did a test once to see the difference from f1.8 to f4 and the difference in visual sharpness was not very substantial, however there was a jump in contrast

Using purely primes, kudos to you Keitha!

I currently "dual-shoot" with Nikon and Pentax for weddings, and I quite often take the majority of shots with just primes - but I find I have to fall back on my nasty Nikon 18-70 for the wide group shots. Other than the groups, I usually put the DA70 on the K20 and a Sigma 30 1.4 on my D80 - I must say that my purchasing of the DA21 hasn't stopped the FA43 lust, it just depends on whether I can get in there before the go up (they have doubled at 90% of online retailers

this is the kind of picture I was after, and thanks for the link to original Gooshin.
I will compare it to my findings.

anybody else has similar kind of shot at 1.8?

ohh and that was off a K20, therefore pixel peeping would be off-setting, if you DL the original, i would suggest re-sizing it to the K10 specs.

Well, I went through my 'archives' and I finally found this one:





Original size.


I have some indoor shots at f1.8 (churches) but this was the only one I found resembling anything simular to what you asked for.
And this one is with K10D.

Why did I use f1.8 here? Simple mistake



ps it would seem that Zenfolio is somewhat slow on my side of the world, lately
