What is a good zoom lens for reverse lens macro?

I've been shooting a lot of macro lately and I find myself bringing both my 28mm and 50mm lenses plus tubes to get a decent range of magnification. It's a major POS to modify my set up on the fly when i only have precious seconds with a subject.

I currently shoot with a Pentax-M 28/2.8, and a super Takumar 50/1.4. So i feel a zoom lens that basically spanned that range of focal lengths would do me quite well.

Id rather it be an old lens as it is more my budget.

Any suggestions?

Cheers, and thanks!

I'll give you a little eye candy for clicking
Shot today with my k-r and a 28mm reversed lens on a 28mm tube:

Nice shot! very much like Thomas one. I believe Thomas use the kit lens in reverse (in one of the video interview he mentioned the lens he use). Thomas: Flickr: Thomas Shahan's Photostream

Thanks LFLee.. Yea he is kind of an inspiration to me. I would love to produce images at that level of quality someday.

I think he has used a variety of methods but from what i have read I believe he uses predominantly prime lenses.

Since you mentioned a zoom lens in the 28 - 50mm range consider the Tamron Adaptall-2 SP 35-80/2.8-3.8 (01A). It has a good reputation as a close-up lens (to 1:2.5 -- MFD 10.6") and I just tried it with a reversed SMC-M 50/1.4 which appeared to offer better than 1:1 simply by holding the lenses together beak-to-beak. It does have a 62mm filter thread so using a step-down reversing ring would be necessary; however, I imagine that would be the case with any fast zoom lens.

The 01A also performs well with extension tubes and with a Tamron 1.4x TC. Although it's not quite as capable as the 90/2.5 (52BB) in the pure macro mode, it's very versatile as a general nature-hunt lens and useable as a portrait tool.

Should be available with a PK adapter for about $100, or $160 with a PK/A adapter for auto exposure mode.

Speaking generally, you will get better results with primes. Zoom lenses can also be quite unpredictable in their working distance when set on tubes, sometimes with the focal plane ending up inside the lens, making it useless. You have a good pair of lenses right now for working with tubes. Another option would be reverse lens stacking, which would get some higher magnifications quite easily. If you picked up something like a 135mm, and reversed either of your current lenses on it, you should get some good stuff (as long as the host lens is decently sharp, too). Your 28mm reversed on a 135mm will be a bit shy of 5:1 magnification (too much for handheld, really, but it can be pretty wild on a tripod with a rail), while your 50mm will attain a little better than 2:1, which should be good handheld, too.

If you really want to try macro with a zoom lens, I'd suggest getting a Raynox or Opteka addon lens. This will keep your working distance constant, while your zoom will affect magnification. Both of these are better than simple +dioptre lenses, in that they use multiple elements to correct for chromatic aberrations, and are generally much sharper, too. The Opteka one is both stronger and cheaper than the Raynox, while still giving pretty good image quality. If you use too long a focal length, it really brings out the worst in your host lens, with some pretty wild distortions around the edges if the host lens isn't flat field sharp. Still, it's plenty usable at the 1:1 through maybe 3:1 range, which is all you should be doing handheld. This is the lens I'm talking about. Below is an example of it in use on my cheap Sigma 70-300mm.

You can find setup references in this thread :
https://www.pentaxforums.com/forums/lens-clubs/143202-macro-any-means-necessary-club.html


The best results seem to be coming from a 135mm + reversed 50mm or 28mm, so you might want to try something like it.
You may also get results with a Good Zoom + reversed 50mm (eg. DA 50-200; DA55-300)
