The Rikenon 105mm 2.8 Macro. As in all macros image IQ is great but there is a bit of art thrown in with the Rikenon. It is my go to up against the A 50 2.8 a Tamron 90 sp and a stack of other macros.

I like the Sigma 10-20 f/4-5.6 lens. It has its weaknesses compared to the more expensive UWA lenses, but it can produce landscapes that I like anyway. It's just a really fun lens to use, when the right light is around. The only thing I really wish this lens had was better sunstars. And, maybe a bit better corner performance in the 10-12mm range.

Have you ever come across a macro prime that wasn't really sharp?

I mean a real macro prime...not one of those 1:4 - 1:6 28mm lenses the resellers called macro...

no no no no no

not the point - I misstated my point; I was looking for the overall IQ of the lens; the bokeh, color rendition, and (of course) how very sharp it is, but the overall quality is so hugely underrated....

I'm a bokehaholic. The following Leitax adapted third-party lenses have incredible bokeh on my K-1 -

1. Zeiss ZF Milvus 85/1.4
2. Leica R Summilux 80/1.4
3. Zeiss ZF 35mm f/1.4

I feel the same way about my Tamron 52BB. But Tamron slapped a SP on it, so it isn't surprising And the SP 35-80 01A. I never thought I would consider a manual focus zoom from the 1970s one of my best lenses...A lens that costs about $40 these days...(depending on if it has an adapter, or what kind of adapter...)

agreed - the 72B should be amazing (it is), but that Vivitar should be just.... average?

No, it should be amazing. Macro lenses were usually the best lens produced by a company. Would you be surprised if it was made by Kiron?

What's really amazing is that almost nothing is known about Komine Co. Ltd. Two different addresses published in the 1980s, gone by 1993...

Having used Osawa and Tamron (and a little bit of Tokina) over the past 35 years, I tend to stick to "smc Pentax-XX" or "HD Pentax-DXX" whenever I can. There are 3 exceptions:
  • APS-C: Sigma 8-16mmm
  • 24x36mm: Sigma 12-24mm
  • 24x36mm:Tamron 28-300mm (model A61)
Out of these 3 exceptions the Sigma 8-16 certainly is the best, but since my main camera is the K-1, I'd say the winner is Sigma 12-24mm 1:4.5-5.6 DG EX, simply because it is the widest AF lens in the Pentax K-mount universe.

I have one of the 28/2s. I've never been able to use it on a DSLR because it has the long aperture shield and one of the screws is stripped... Actually the 28 is a Kiron...

Great Vivitar 28mm Bestiary: Details

I do have a Komine Vivitar 28/2.8 in Minolta MD mount that I paid $15 for...

I also have a 90mm F2.5 macro labeled as a Rokunar. Haven't really used it because 1. It's kind of heavy, 2. The focus ring is very stiff (and it has to be turned really far), and 3. I have 3 other macro lenses...

Vivitar (Komine) 90mm f2.5 or f2.8 Macro Lens Reviews - Vivitar Lenses - Pentax Lens Review Database

Mine seems to be a late version with the A setting, but no A setting lock. (I had a 28mm Gemini that didn't have the A lock either).

And of course don't forget the third version of the Series 1 70-210...

I only have three third party lenses - Samyang 12/2.8 Fisheye, Sigma 35/1.4 Art and Lomography Daguerreotype Achromat 64/2.9 - each one fills a niche which Pentax currently can not.

Which one do I treasure the most? The Daguerreotype - because it's beautiful, brassy, quirky and relatively rare. But it's not my favourite by a long shot.
