90, 100, 105 macros not "constant f/2.8"?

THANK YOU Class A for mentioning that. You sent me back to Amazon for reviews on that lens and I discovered the source of the statement that I was struggling to remember when I started this thread. That statement is here:

Amazon.com: Peter Chenoweth's review of Sigma 70mm F/2.8 EX DG Macro Lens for Niko...

It was made NOT in connection with the 90/100/105 macros but apropos the Sigma 70. I'm glad that I found it because it was driving me crazy!

To reconfirm: When you use a macro in non-macro situations, it will behave just like a regular lens and the images will look the same.

Great, thanks!

Tried to find the thread, but no luck.

Is this for (pre K-7) Pentax cameras only?
