I have been doing research and I have been told the Kiron 105 macro lens. Produced by Kino Precision (Japan) from 1984-1987 is a great Macro Lens the down side of course is the lens is a FD mount so I would need a Adapter most of the cause a loss of a f-stop this would be used mainly for photographing my and other fish tanks corals so I was looking for thoughts on a this lens plus a good adapter mount it was either this or I was getting the Tamron 90mm :scratch
Camera 40D (sweet) Yes I am still trying to learn to use it! Father,Dog Lover,Computers,Aquariums And loving life! :barb

    There are 2 types of FD-EOS adaptors - ones with optics to maintain infinity focus - and ones without, which essentially end up doing the same job as a thin extention tube (as well as being a mount converter)

    Canon themselves only made a limited number (I've seen 500 mentioned, but dunno how accurate this) - these are very good optically - but rather expensive (if you can find one) - and you'd have to check whether they'd work with a particular lens - because of protruding elements (similar situation as with current Canon EF extenders)

    Third party converters (with optics) vary a lot in quality and if being used with a macro lens then this aspect (IQ degradation) should be considered.

    Depending on the field of view / working distances you're after - a basic converter (without optics) would probably be the best bet imo (as well as being cheaper) for your purpose.

    If you're taking pics of static objects, then the downsides of using a (manual) lens system that doesn't let you use the full capabilities of your dslr (esp. flash) are fewer than if you're chasing insects or similar around :)

    Whilst I've used both a Tamron SP90 and a Canon 200mm macro FD lenses (with home-made, non-optical converter) on D30 / 10D for a couple of years and got some reasonable pics - I'd strongly suggest considering buying a macro lens with an EF mount ... and get all of the benefits (esp. for flash based work) that this combo (40D) will provide.

    Having used both, I know which I prefer - others may well have different experience.
