Tokina lens question: I have a Tokina lens that I used a lot with my Pentax K10D, especially for macro work. It is a zoom, maxing out at 200mm and 2.8. I have now joined the Nikonites...

I have a Tokina lens that I used a lot with my Pentax K10D, especially for macro work. It is a zoom, maxing out at 200mm and 2.8. I have now joined the Nikonites and my question is, can a lens be factory "retooled" to fit another camera? I would like to keep the Tokina if I can use it on my new D7100. Any thoughts?

If your Tokina is a zoom lens, then it is not a true macro, as it cannot capture 1:1 magnification (life-size). Tokina makes the same lens in 'F' mount (Nikon), so converting your Pentax-mount lens could be expensive, because this is not common.

I advise you to consider one of the following true macro lenses: Tamron 90-mm; Tokina 100-mm; Sigma 105-mm; or Nikkor 105-mm.

I agree entirely, this is NOT a macro lens.
You can purchase custom made adapters from several companies, but as you are in hiding it would be pointless me recommending one.

As he's docTexas then I guess that's where he's from! But I agree with your sentiment regarding members in hiding

Thanks, y'all for the responses. As for the "in hiding" entry (and any negative connotations here), it was apparently added to my name, and not my doing. My apologies as a newbie to the forum; I will try to rectify it. BTW, I am from Central Texas: Georgetown, just north of Austin.

Did not wish to sound negative, my apologizes.

Apparently the zoom has been used for close up work and he is happy with it. Technically its not a macro but so what.

I agree that retooling would be impractical.

Thanks again. Yes, I used it as a macro, but also as a regular zoom lens. I like the way it is built (metal!), and also the fact that it is a 2.8. I checked out the adapters suggested and they are quite expensive. So, I am still stuck with a lens that sells for $450-500 but one that I can't use on the d7100.

Most macro-photographers take good care of their macro lenses. That means most used macro lenses are in great shape. Consider buying a used lens. My first true macro lens was a used but immaculate Nikkor 105D (A-F but no VR) that I purchased for $400. 2-years later, I sold it for $400, when I purchased a used Nikkor 105G (A-F + VR) for $800. Still using that lens.

Now that's clarity! Borderlining digiscoping for Pete's sake.

Hi, I have read elsewhere on the Hog that Nikon are to make third party lenses un usable with their cameras, so you may wish to seek further advice on your choice of lens.

If I were in your situation, I would sell the lens on ebay and buy a new one.

Anything can be done given enough time and money. In this case though getting a proper model will be faster and probably less expensive overall.

Good luck.

Hokey smokes. What would that look like with a D5100 (16.mp)? I have not ventured into macro yet. Still trying to master the kit lenses for the D5100. That is an amazing photo folks. I hope you take the time to download this if you have not looked closely at a true macro photo! You make me want to sell my equip. and try and find another hobby.
