p.1 #1 · Canon 2x v3 vs sigma apo 2x


Anyone ever use both? I'm using a sigma 120-300os and I really like the 2x sigma, but was wondering if I could sqweek out more detail with the new 2x from canon.

Thanks!

You can try my 2x III, if you visit Halifax.

I have both and also the Canon 2X v2. I would say the Canon 2X v2 used to be the only game in town for 2X TC, and the V3 is even better. You will see a clear improvement in contrast and sharpness.

But you shouldn't believe me, you should meet up with Jim and try

I am not sure if it can be mounted on your lens, it cannot be mounted on the 150 macro, but the Sigma tc can.

Yes sir, and we can do the great 509 shootout at the same time! Maybe next weekend?

Maybe, next weekend. That would be 20-12 July. I'm sold out for 13-14 July.

Yes, the EF Extender 2x III can be mounted on the EX 120-300/2.8 OS.

I posted example photos of this lens with the Extender 1.4x III last year,

http://www.fredmiranda.com/forum/topic/1157717/0

Unfortunately, I can't find any examples of the 120-300/2.8 OS with 2x III, and I don't have the lens, anymore.

OTOH, I can say this - IQ from the Extender 2x III is a lot better than from the 2x Mk II.

I figure if the 2x III is better that the Sigma APO 2x, then lowa2 owes me two beers. Afterall, "APO" is supposed to be way better than "III". Otherwise, we're even. He buys the first one.

Did you test the Canon 2x III vs Sigma 2x APO EX in the end? Verdict?

I do have both on a EF300/2.8 IS L. I initially bought the Canon 2x III, because this lens deserves the best. However, I discovered "too much" softness with Canon 2x III. Now I tested both next to each other, The Sigma is clearly sharper. W.r.t. color/saturation I have no measurements or opinion yet.

Hi imcor,

Welcome to FM.

lowa2 and I haven't had a chance to meet up, yet.

Charles, do you still have that Sigma 2x TC ?

Are you saying that on the 300 f.2.8 that the Sigma is getting you better results than the Canon Mark III? I will respect your opinion because I've never used the Sigma TC. However, from all the research and forum reading I've done, I've never seen anyone even try to claim that any TC at 2.0 level is better than the Canon 2.0III. Especially when paired with a Canon prime lens.

Have you done MFA on the TC/lens combo? The TC/lens combos always need some MA in my findings and the 2.0 usually needs more than the 1.4. I've MA'd the Canon 1.4 and 2.0 IIIs on my 100-400, 300II, 600II and 70-200II and all of them needed the most MA when the 2.0 was attached. If you have done this then disregard. If you haven't then it would be worth a try because I truly believe your original assumption was the correct one.

Hey Jim,

I don't have the sigma 120-300 anymore. I regret selling it, but our baby just showed up last night and priorities change quickly!

I do however still have the sigma 2x!

I have to say that I was surprised myself. I was disapppinted about the Canon 2xIII. I got at the point that I doubted that going from 1.4x to 2x was adding anything beyond image scaling (no futher detail). I already did micro adjustment for the normal AF and the Canon2x. I have to say that the pictures I compared were taken with the live view and its AF. I will do some further tests.

Not using this to brag or show off my images as these have all been posted very recently on the forum but are you getting results like these with the Canon/Canon combo or the Canon/Sigma combo?
