Use of Canon 100 macro with 1.4 teleconverter

[JAB1]

:shock: I tried to place my Canon 1.4 teleconverter on my Canon 100 macro lens and it would not fit....I had read on an earlier forum somewhere that it would work?...Has anyone had any experience with this?.....I would like to use this combination for more closeup capability if it will work....AB

What can we tell you,. you have the parts so you can see.. it won't work.

Canon has a list of all the lenses the T-cons will work with. Perhaps whoever steered you wrog was NOT using a Canon T-con? There are third party T-cons that are designed so that you can use them with more lenses,. but the quality may not be as good.

I'm just curious...why would you want to use a teleconverter with a Macro lens?

Because 1.4:1 is way cooler than 1:1. :)

Check out the Macro World forum over at FredMiranda.com - some of those guys do some amazing things past 1:1.

What you want to use on a macro lens is an extension tube. There are various sizes available. Different animal altogether.

Don't forget diopters - preferably the 2-element ones like the 250D.

Actually, the nice thing about the TC is that it doesn't change the minimum focus distance. Both tubes and diopters mess up the focus distance.

Kenko makes TCs that should fit the lens. I've heard good things about them, but I've also heard that they have some quirks.

Yeah, it makes sense, but I would think the loss of light and image quality from Teleconverters would really show in Macro. Maybe not...I've just never tried it. I've just always used converters with telephoto lenses and extension tubes with Macro. Maybe it's time to try something different.

Sounds like you should try a high-quality diopter like a 250D. If you're using a 10D you won't see any image quality loss on the edges. Very little light loss if any, fairly high magnification.

You can put a 12mm extension tube between your 100mm and your 1.4x and then it will fit.

Oh yeah! I had forgotten about that trick. And I'm due to get my Kenko set tomorrow... Thanks!

I've been pretty happy so far just shooting 1:1 with my 90mm Macro lens. I may try putting my converter behind it and see what happens.

What about those wacky mounts that allow the lens to be mounted backwards? Those are some wild looking gadgets with mounting receptical for both ends and wires running to the connectors to maintain electronic operability.

Anyone actually used one? the concept is interesting at least.

Yeah, I used reversing rings 30 years ago...but the cameras were not autofocus at that time and were full manual.

I am considering a buy on the Canon 7-0-200 2.8 lens.

B and H has a teleconvertor that says it is for EOS with 90mm and larger. Is this due to the mounts? Has anyone used this on the 70-200?

You can use the Canon 1.4 on the 100 macro if you put an extension tube (like the 12 mm) between the 1.4 and the lens.
