Nice collection!

Nice collection!

Neatly organised too!

Considering you intend to use said lens(es) on your KP, I imagine you want to keep things relatively compact and light. The Voigtlander range would fit the bill. But trying to get one in K mount is problematic. Quite a few 40mm SL 2 Ultrons available from Japan, but in other focal lengths the choice is rare and expensive. I own an original 40mm SL and 75mm in m42, but unless you have the auto aperture removed, they can only operate at max aperture on k mount cameras.
I would also consider the original k mount lenses, especially the 28mm f3.5 or 30mm f2. 8 or the FA Ltd range of lenses.

I'll recommend: SMC/SuperTak 150mm f4

K150/4 is same lens as SMC 150/4.

Great collection, but please tell us what they are. I can take a few guesses but they will be just that, guesses.

If I could see f-numbers and minimum focus distances Iwould be able to do better, but that is not possible. Nobody stores a lens at its minimum focus distance, so I can't blame you.

Which of the macros would you recommend getting first?

[pschlute]

Which of the macros would you recommend getting first?

I don't do any macro work so i could not comment. One of them (I cannot recall which at present) has a bit of cloudiness due to I think balsam separation. If you are looking for one I suggest you check that out carefully as it is not an easy fix.

[iheiramo]

Which of the macros would you recommend getting first?

Probably M50/4. It's great from wide open, works well from macro to landscapes and focal length is more flexibel. If serious about macro, I'd go for modern macro that gives 1:1 magnification. M series macros only give half of that and you need extension tubes to go for 1:1.

[photoptimist]

Which of the macros would you recommend getting first?

The choice depends on your macro goals:

Go for a long focal length macro (100 mm and up) if you want to shoot insects and other skittish creatures. A longer lens lets you be further from the subject.

Go for a short focal length macro (50, 35, or shorter) if you want to go much higher than 1:1. A shorter lens needs less additional extension/bellows distance to get to high magnification.

For some reason I've happen to acquire many macros (50s mostly)... This is just some notes:


M42s:

-Preset Macro-Takumar will do 1:1 at 50mm and it is a beauty. Slow at f4 wide open.

-Vivitar (Komine) 55mm will also do 1:1 and it is faster at f2.8 (sorry, not a pentax brand)


K mount (my experience is limited to 1:2 macros here):
-K 50/4 - lovely and sharp, but slow at f4
-A 50/2.8 - really nice and faster.

-A 100/4 = it is a good lens, but be aware that the A series suffers from haziness in the front group due likely to the cement holding the elements together.

If I had to keep 2 of the bunch = the A 50/2.8 and the macro-tak preset 50/4.

Note - Sigma EX line has some good macros (Pepperberry's got great examples on these) - but again OP was looking at Pentax glass.

he did mention some other brands (at the tail end of the OP)...

I only have the Sigma 70mm macro, but several other macro lenses from 35 to 90mm....
