Non-Pentax old macro

Does anyone own or have used either an old m-type Sears or Promaster 135mm f2.8 macro lenses? The reason I ask is that I would like to try macro, but don't want to spend too much to see if I like it. Any opinions would be appreciated. Thanks in advance...........................................Paul

PM sent. I happen to have a Sears 135 macro that Ill let you have for a song!




There's also the Vivitar 55 2.8 macro in my sig (1-1 magnification!) - I'm going to sell that, because I never use it now that I went crazy & bought a FA 50 2.8 macro and a 35ltd macro in the last 60 days.

Oldschool, please realise that these 135mm "macros" don't normally go larger than 1:5. You'd get better results with a Tamron/Sigma 70-300mm. Or even cheaper, just get some extension tubes.

Yeah, the Sears only goes to 1:5. It's not really a macro, just a 'semi-close-focus.'

I think I agree that the $139 dollar tamron 70-300 might do better than the ones you mentioned. Also a 40 dollar raynox 250 on the front of any of your lenses will do a good job too. The raynox is pretty versitile and can give you a good sense if you are going to be interested long term in macro shooting

Here is a tamron 70-300 shot from monday...

And here is a shot with the raynox on a DA 50-200 at about 80mm zoom


good luck

Thanks everyone. One of my questions was the magnification factor. I appreciate your help. I may try extention tubes with my m50.

I would believe the greatest non-Pentax old macro would be Vit Series 1 105mmF2.5. An all around (1:1) great performer indeed. It used to be available at around $130. That has been increased since then and by quite a bit now (like 2x). Good old days.

Sears and Promaster 135mm aren't real macro lens. IIRC they do up to 1:5 close-up. For a cheap macro lens, you can consider Promaster/Cosina/Vivitar 100mm 1:2 macro which comes with a 1:1 macro adapter. Not the best of the macro lens, but they used to go for around US$100.

If you want something more than 1:1 macro, try reverse a lens. Look for cheap primes that's below US$50, and an adapter for <US$10. 50mm gives abt 1.1:1 or 2:1 macro, 35mm gives abt 1.6:1 macro, 28mm gives abt 2.2:1 macro, 24mm gives abt 2.5:1 macro and 20mm gives abt 3.4:1 macro. However, the magnification changed with diff lens.

IMHO best non-pentax macro are Tokina 90mm f2.5 (with 1:1 mout adapter), Kiron/Vivitar/Lester Dine 105mm f2.5/f2.8 macro, Tamron 90mm f2.8 macro.

I have an old sears 80mm-200mm lens which is macro, but I was adviced today that as it says KR on the lens it may well get jammed on the camera - the thread is 135mm takumar lens - a very helpful member suggested reading a web site that explains all this - the net result is do be careful to check if they are compatible

OK found the link from the other member..

Mark Roberts' fine site has this information about the Ricoh lenses and compatibility. Scroll down and there's an explicit warning to avoid KR lenses.
