I have a question about the 3rd party lenses on Pentax k100D or k10D (waiting on body to arrive still).
From what I read in the online PDF manual on SR system of these two cameras, it requres for the lens to let camera know the focal lenght the lens is at a the moment of the shot.
I know most later model lenses from Tamron and Sigma (such as 17-70, 70-300 etc) do convey the focal lenght information, at least to my Canon 350D (as I can see it in the exif data)... At least that is how I understand what is says in the manual (pages 69-71 of the document
http://www.pentaximaging.com/files/product/K10D_Manual.pdf )
In the real world, if you have any AF third party lenses, does SR work automatically or are you prompted every time to enter the focal length manually into the camera?
Thanks for your time!
Regards,
D
EDIT - I was not sure to post here or in the lens section (since it involves the body and SR of the DSLR...)
