I have the following lenses that I received from a friend:

SMC Takumar 1:3.5/28

Super-Macro-Takumar 1:4/50

SMC Takumar 1:2.8/105

SMC Takumar 1:4/150

All in excellent condition, with cases, etc.

My question is:

I have the two kit lenses (50-200 f4-5.6 and 18-55 f3.5-5.6) that came with my K100, plus the adapter.

Aside from the 1:4/50 super macro, is there any benefit to holding on to the other lenses, or should I e-Bay them and apply the proceeds to a new 300 prime?

All recommendations VERY welcome.

IMO you might as well sell the 3 takumars- screw-mount lenses are not very practical when used on a bayonet-mount camera...

I'd be happy to take the 105mm off your hands!
Just kidding, keep it and use your K mount adapter for it.
It's a great lens.

The macro is a good lens too, but at f/4 only it is somewhat difficult to focus when doing macro work.

The 28/3.5 is one of the best 28mm lenses Pentax has ever made.

The 150/4 isn't that great - expel it.

YIKES, Mo! No way! I love my screw mounts! (I just replied to another post - if you remove the locking pin you can use the M42 lenses just like bayonet ones.)

The SMC Takumar 28/3.5 is one of my favorite lenses, period. It is sharp at all apertures, free from distortions, and has very nice color/texture reproduction. I spent some time in New York City and I alternated days between this lens and the ($800) 31mm Limited. I was not unhappy with either lens!
The 50/4 Macro is interesting. I'm sure it is a great lens, but it is going to be darn near impossible to focus with it stopped down. Usually for macro work I shoot at f/8 or smaller, and there isn't much light coming in at those apertures.
The 105/2.8 is a really sharp lens. The bokeh is so-so at f/4 or wider, but if you want a *sharp* mid-telephoto lens, this is a good choice.
The 150/4 (I have one) is an odd focal length for me - I seem to always want more or less when I have it on the camera, and the f/4 maximum aperture is not very bright. It is one of my lesser-used lenses.

If you were selling on eBay, you should get a good amount for the 50 Macro and 105/2.8. I'd cry if you sold the 28mm so I won't hypothesize on its value. I think the 150 gets you the least, but still a decent amount. These are all good lenses!

Hi,
Would you mind pointing me to a link that explains what you mean by removing the locking pin?

Thanks,

Ken

I don't think I have any pictures off hand, but it is pretty straightforward. On one side of the adapter there is a little metal hinge that is screwed into the adapter. This allows the adapter to firmly 'click' into place when bayonetted onto the camera. If you simply unscrew this hinge, the lens will no longer lock onto the camera.

With the lenses mentioned in this thread, there is still plenty of friction that keeps the lenses in place - there is no risk of them unscrewing and falling off. I've been using mine like this for the last year or so. YMMV.

clm - Sean means the locking pin on the m42 - K adaptor not the aperture pin on the M42 lens. If you buy enough adaptors then all the M42 lenses have kmounts and the practical issues of juggling a single adaptor vanishes. you could go the whle way and locktite the adaptor on the lens base. That would have an effect on the re-sale value though I guess.

That lens pin should only be removed on some Ricoh lenses that stick in the auto focus drive shaft hole in the mounting plate on the camera.

Any update, Tom? Which ones did you keep?
