My old 70-200 EX (not DG, not macro, not HSM) reports correctly. Seems silly if they dropped this.

I have the old DG non-macro model.

**Lowell Goudge** · 11-03-2008, 08:30 PM

my APO 70-200 F2.8 EX (non DG non macro) also reports correctly, but as I said, my 10-20 does not. caught me by surprise, when I saw it, but really who cares. when you see the focal length correctly you know (usually) what you shot.

My new 70-200 has very little give - it seems to be as tight a mount as any of my other lenses.

It reports correct focal length.

krypticide · 11-04-2008, 12:59 AM

Does it report the name of the lens?

bonovox · 11-04-2008, 04:55 AM

Where do I look to see if lens name is reported correctly?

I use Kuso EXIF viewer, there are tons of EXIF viewers and editors out there for free

I've got CS3, and PhotoME - but don't know where to find this info in either program. I'd prefer not to download another one, since I have no real use for it.

Just to clarify something: a lens does not send its name to the camera, only a numeric ID. That is all that is recorded in the EXIF data. How that ID is translated to a name is up to the EXIF-reading software.

There have been many reports, for a long time, of Sigma lenses being loose when mounted on the camera. I have a 70-300mm APO that fits snugly, but I had a 400mm f/5.6 that had quite a bit of play.

I've never heard these complaints about other brands, just Sigma...

I only have one Sigma lens, the 24-60 f/2.8 EX--and in the latest lightroom it reports "SIGMA" for the lens name. I didn't note any special looseness in the mount. Most of my autofocus Pentax lenses have better names though the new DA 55-300 doesn't return a lens name. I'm inclined to believe that as RBellavance said that a future LR update may fix this, at least for the 55-300. It may be that Pentax only reserved one ID for Sigma to use for all of their lenses, which seems someone sensible if you're the owner of the mount and have a finite # of IDs available (I'm just guessing, this may not be the case).

I have the sigma 70-200 HSM version and found I do have some play but when munted in the monopod via the collar it seems less.put it doen to the glass weighting 1.3kgs compared the the K10D and battery grip approx 1kg

cheers

In case I forgot to reply, I now know that a little looseness is normal and that Lightroom has problems identifying the lens, but PhotoME reports it correctly.
