From what I can gather, extension tubes work fine with the 100/2 ZE but you cant normally use the canon TCs as there is a risk of the rear lens element hitting the TC when focussed to infinity.

Presumably though, you could get around this by sitting an extension tube (12 or 25mm) in between the 100/2 and the TC.

Wondering if anyone has tried this combo? (either for macro or standard shots) - Any comments?

Given that its quite possible to stop down past f2.8 (1.4X) or f4 (2X), do you lose much in IQ?

The front baffle on my EF2XII will just contact the Z100's rear element but the EF2XIII baffle is 0.5mm shorter and just misses.

I've used the EF Life-Size-Converter with the Z100 and it works well for macro shots....0.85x at MFD.

Wondering if you have you tried putting an extension tube between the 2X TC and the 100/2?

I haven't but I'll give it a try and get back to you tomorrow (or maybe tonight in Melbourne)

With a 12mm tube and 2x, you'll get 1.15x magnification with 185mm working distance at MFD. Infinity focus occurs at around 650mm WD.

thanks Bob. Much appreciated

Seems as if the 100/2+2XTC+ tube combo is viable.

Was also quite interested in your comments on the life sized converter as had never considered it previously. Is there any advantage that the LS-C offers that you couldnt get with the 1.4X TC (or 2X) +tubes? Read up on it and it seems as if it might be a good option/alternative to the 1.4X TC (appears to be approx 1.2X), advantages possibly being AF speed? IQ? vs decreased max focussing distance

Now to work out what combination to get - I've got about 1800 in store credit atm, of which 1300 will go to a fuji x100s (need a walk around) -> leaves $500 odd for spending (+ potential for a bit more)

options seem to be
1. life sized converter + extension tubes (12, 25 or both)
2. 1.4 X TC + extension tubes (12, 25 or both)
3. 2X TC + extension tubes (12, 25 or both)

The main advantage of the TCs would be that it could also be used on a 70-200/2.8 IS II at sporting events (stadium limit 200mm lens) and potentially to dabble in wild life/bird photography.

For sports, I *think* I might be able to get away with IQ issues by stopping down 1 extra stop at a night game (happy with SOOC raw conversion images taken via aperture priority hovering around 1/6400 @ f2.8 and 1/2500 @ f4 (ISO 10,000) -> I'm thinking that becomes 1/1250 @ f5.6 with 2X TC -> 1/1000 @ f8, ISO 12000+ for further stopping down (with PP)

or perhaps I should not be greedy and just stick with the 1.4X TC + tubes combo (better IQ with 1.4X TC)

Which combo would you recommend to start off with? (for macro + longer shots)


1DX, x100S, 24-70 II L, 100L, 1.4X TC III, 25/2 ZE, 35/2 ZE, 50/2 ZE, 100/2 ZE, 120-300/2.8 OS S :)

Sorry for the delay....

The longer shots aren't viable with any of the combinations mentioned due to the maximum focus distance being less than 1 metre. I think something like a Kenko 1.4x or 2x DG will possibly serve you best for flexibility (I haven't got one to offer a firm opinion about it though).

Your assessment of 1.2x with the Life-Size Converter is very much based on the lens it's attached to and the method of focussing employed by the lens.
It acts as a 2x when used on the EF50/2.5 but has less potential increase with longer FL lenses.

I have used the Kenko 1.4x TC successfully with the 100MP many times. I believe the 2x will work, but I do not own it so I cannot test that combo.

thanks heaps for the responses.

Just checked prices for australian stock of canon teleconverters and tubes are about 60-80% more than grey pricing :( - means I will buy grey and use the approx $500 credit post x100s for other things

Just an update - ended up getting the canon 1.4X III afterall - only been using it on the 70-200 II atm and loving it.

Now just to get some extension tubes before trying the 1.4X TC with the 100/2 ZE :)
