Hi there,

I was wondering if anyone can advise me on this: I have the Tamron 90mm macro lens on my Canon450d but I`m trying to go even "beyond" 1:1 magnification without having to spend a fortune.Has anyone used this lens with extension tubes if so was there a great deal when comparing the images?Any advice is more than welcome.
Thanks.

I use the Canon 100mm 2.8 (old version) and have recently bought a Raynox DCR250. The results are really good, and it's a very affordable addition. Tubes have both pros and cons (for example the loss of light); the Raynox has only pros IMHO, taking into account it gives a very high quality.
I have a few photos here:

But "the queen" of Raynox is Marta :-)

I'd recommend trying it, no doubt!

I did use extension tubes in the past. I think it is sort of fun (and they are cheap). Not very handy but fun. One good thing with extension tube is that they do not affect the lens quality (it is empty, no additional glass). So if you are using it with a very good and sharp prime you will get very good results. Now the macro lenses are optimized for macro shots and they generally provide a specific sharpness relevant for macro (and also they generally can be stopped down more than regular lenses). So I think the result with extension tube is kind of softer if used with non-macro prime, but if the prime is good I would say it is softer in a nice way (FYI I did use extension tubes with Nikon AI 50 and 135 primes which are very good lenses).

Note that extension tubes are more relevant for static subject matters (flowers, macro close-up, document reproduction ...). With moving bugs it can be tricky.

Yes i use it frequently and never got a better one in hand for such price! I use it on Nikon and try it out on many models and the result are very good. The details and sharpness is awesome! The only disadvantage is the autofocus which drives me sometimes crazy. I have used this lens also on my film camera and the results are even good. For the small wallets it is the best you can find! This Raynox magnifier have also a very good quality!

Thanks for suggestions guys!

Sorry for butting into your thread Dan. I have question for Raynox users, can it be used wth micro nikkor 200mm f4 to go beyond 1:1 magnification? Thank you.

I have a Canon 250D Close-up Lens, it works great with my EF-S f/2,8 60mm. Macro.

Thanks guys.Anyone is welcome to share their views on this matter.

I have sometimes used Kenko extension tubes with my Tamron 90mm.

Since the formula for the magnification is (ext. tube mm + lens mm) / lens mm, the tubes would be more effective with shorter macro lenses.
The three rings in the Kenko set gives 1.75 magnification when all used.

The loss og light I have never given much thought, since I always use a flash when shooting macro.

A couple of examples where I have used extension tubes:

Thanks Jens but I have just purchased the Raynox DCR250.At the moment I`m experimenting to see how it works...first attempts are disapointing though(it`s me not the glass).More work required!
