Okay then a personal challenge. I need to do the following:
find my own cult lens ( I swear it's here somewhere)
dig out my 200mm len, a vivitar autofocus with matching 1.4 converter
and a tamron adaptal 200mm lens
start using my pentax macro lens again
For a list of some of the "cult" lenses see these archived pages. The pages on the original site appear to have gone missing but live on in the Wayback Machine.
My adapter arrived today for the gen 3 version..... wow, is it sharp.... but on a downside, they gave up some of the macro abilities in exchange for sharpness in normal operation.
unless Im doing somethign wrong, min macro focal distance for gen 1 is about 3" whereas the gen 3 is about 30"
so basically, they gave up macro in gen 3.... but my goodness is she pretty elsewhere
No, the gen 1 has a better macro mode, the optics actually shift around inside. I'd have to look up the specs (I gave you a link to a scan of the manual) but as I recall it gives a better magnification ratio than the later generations.
Have copies of all 3 pdf files stored on laptop
The difference in macro minimum focus distance was the big surprise though.... (confirmed by the manuals, so Im using it correctly)
Around 3 inches for the Gen 1, over 20 something for the Gen 3
(Macro mode by definition only I think LOL)
For our use, If i had to choose just one.... it would be gen 1.... what an amazingly versatile lens.
Having said that, no regrets in buying the G3, man.... is it nice at doing everything else.
and I do have my lil ol macro lens for when the need arises
This thread makes me want one. For so cheap, I feel like it's not worth NOT having one, especially since it's obviously extremely versatile. Gotta start lookin' into this... ^.^
Back in the 80's lens manufacturers started designing their zoom lenses so the minimum focus was under 1 meter and started etching "Macro" on the focus ring. Technically it should be "Close Focus" not macro because the magnification was seldom equal to or better than 1:2 (0.5x). However "Macro" fits better on the focus ring and sounds better as a sales point.
So if you're looking for good macro performance skip the zoom "macros" except a couple of the early Vivitar Series 1 zooms.

Here is my contribution for today. These were taken with a Vivitar 28mm f2.8 Wide Angle Close Focus. This one seems a little rarer than the Vivitar Series 1 70-210mm. This is a tiny little lens compared to the 70-210 as well. Not my picture, but shows what it looks like: http://2.bp.blogspot.com/_wkkNFjEoM...AnA/s1600/Vivitar_28mm_f2-8_CloseFocus_01.jpg. Composition is not the best. These were just some quick handheld shots I took tonight.
I'd also like to add that the focusing distance on this lens is about 6-8", so certainly not a true macro (hence 'close focusing').
