- Macro lens choice for APS-C - PentaxForums. com
The Tamron macro lenses - even from the 1980's - have been simply stellar throughout all of their iterations, even on digital If your macro interests include insects, spiders, etc the greater working distance of a 90mm macro will generally be more useful than the DA 35 Macro, although that is an outstanding lens
- Starting Macro - PentaxForums. com
My main macro lens is a Tamron SP Adaptall-2 90mm f 2 8 (model 72B): Tamron SP MF MACRO 1:1 (72B) 90mm F2 8 Lens Reviews - Tamron Adaptall Lenses - Pentax Lens Review Database This 1:1 manual-focus lens was introduced in the mid 1990s, so it's not a modern lens
- Pentax Lens Disassembly Database - PentaxForums. com
This is a great lens in many ways: great optical quality, excellent macro capability, and cheap and commonly available The DAL plastic mount version has the exact same optics, and even has quick shift with the release-button trick!
- Sigma APO 300mm F4 - Pentax Forums
The IQ, bokeh and abilities to absorb light are no less than those of 400 5 6 APO Macro, which I appreciate very much Compared to my latest addition, Sigma 100-300 F4 APO EX, its images look slightly less sharp wide open - in exchange for more dreamy rendering and retaining noticeably more layers of light as your eyes can observe
- Soligor MC Access hanimex. . . 35-70mm F2. 5-3. 5 - Pentax Forums
This soligor 35-70mm lens looked interesting so I picked it up cheaply It is a rather typical ?early 1980's metal 'n glass zoom lens with quite a high spec: fast at f2 5, built in macro mode which is a built in extension tube, rather like the tamron adaptall zooms 28A (28-135mm), 40A (35-135mm) etc thus giving closer focus at all focal lengths, max repro at 35mm

- Tamron Adaptall (QZ-35M) 35-80mm F2. 8-3. 5 - Pentax Forums
The Macro Mode Button allows a ring to be rotated to the Macro setting, whereupon sliding the zoom moves the whole optical assembly forward, acting therefore like an extension ring (the SP 60-300mm 23A and the 35-135mm 40A , for example, are similar, this is a mode tamron used a number of times)
- KP and a manual focus macro lens - PentaxForums. com
I have a KP and a couple of macro lenses (Sigma 50 2 8 manual focus and Tamron 90 2 8 autofocus, both 1:1), even though I don't do that much macro One of my lenses is autofocus, but I use both in manual focus When I shoot macro 99% of the time I am using a tripod, therefore I am also using 2 sec delay, live view, focus peaking, and magnification
