In France current price for ordinary 4/100 macro is 150 €. 95 for Dental version is a good price ! Michel

However, I've never really heard of a whole lot of "excitement" over collecting them... > What is a good price to pay for one?

There are (from my experience) no poor Pentax macro lens designs. And there seem to be (from my experience) no poor 90mm, 100mm, or 105mm macro designs from any of the 3rd-party companies, either. My wife uses the A 100/4 Macro (optically the same as the M and the dental), and it's a good lens (although my favorite is the A 100/2.8 Macro). My only negatives about the Pentax 100/4 Macro design are that f/4 is sometimes a little slow, and that the bokeh is a little harsh (but this is not an uncommon macro trait). Fred, K1FW
RE: Some technical questions (dental macros)
Some of the specialized Dental or Medical lenses I have seen, are in fact just like an 100 mm macro lens optically. However, many have a built in flash that surrounds the lens to allow flat lighting for the subject. This would be like buying a regular 100 macro lens and an AF 140C flash that has a circular flash head that clips on the the front of the lens. ...cheers! -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: May 30, 2003 3:30 PM To: [EMAIL PROTECTED] Subject: Re: Some technical questions (dental macros) Just a plain old 100mm macro lens...

Re: "Dental" macros
Boz I have the Dental macro and the "dental macro kit" that is quite rare... They also use the colouring system you talk about...

"Dental" macros
Hi all, We know that the M100/4 and A100/4 "dental" macro lenses are mechanically and optically identical to the "non-dental" macros, and that the only difference are the magnification ratios in yellow and and red. But now I am not sure if the word "DENTAL" is part of the name enscriben on the ring around the front element. Does anyone own one of the two dental lenses? Can you please tell me the exact lens name? Thanks a lot and Happy New Year! Boz
