Sigma 15mm fisheye

[torags]

Does anybody know what afd means for a Sigma 15mm fisheye EX

My guess is af=auto focus; d=?

I have a serial number anywhere I can check the date of birth?

Thanks

Digital?

Well...the "D" on a Nikon lens means distance. It's got something to do with measuring the distance to the subject for flash purposes. I'm reasonably sure it means the same thing on a Sigma as well.

It could mean "diagonal" (rather than circular), since it's a fisheye (just guessing)

I just picked up a 15mm 1:2.8 D EX ser. 1015XXX.

Seems to be the version right before the latest DG(Sigma labels this as Digital with improved coatings).

I picked my copy up from a local fellow who said he bought it new six years ago and never used it once. :smile:

My version/copy seems to do quite well into the sun and has nice contrast/color as well as sharpness - even without the newest coatings.

Missed your comment there Mark. I'd have to agree.

Was yours rechipped?

I have a D700 and I've seem some mentions of canon bodies needing rechipping no mention of Nikons (that I have seen)

No. Although I had a Sigma 24-60 that worked perfectly on my D700 but not on my son's D7000.
