Canon TC on Sigma lens?

[andyjayh]

May be a stupid question but I thought I would ask anyway I have a Canon 1.4x TC and I am thinking about buying a Sigma 120-300 2.8, sooo, will the Canon TC be alright on this lens or will I need to use a Sigma TC?

Ta,
Andy

Canon TC's are only suitable for certain Canon L lenses, Sigma TC's will fit certain Sigma lenses, see if yours is on this list ---> http://www.sigmaphoto.com/lenses/lenses_tele.asp

A quick bit of googling pulled up this result on page 1 ...

I think (but can't be 100% certain) that anything that will take the Sigma TC will also take the Canon.

Thanks guys. Still uncertain about the compatibility between the Sigma and Canon TC's but I know the lens will work with a TC.

My Canon 35-350L was not meant to work with a TC but when I tried it out it was fine. The only issue is when extended out to the far end of the focal range the lens stopped down to f/6.3 and the AF got a little less accurate and searched around before locking on.

Hi, just checked with my gear: 120-300 + canon 1.4x TC works fine on a 40D. Not sure if there is any difference in image quality though, as I tend to use my sigma TC with sigma lens, and canon TC with my canon lens.

I don't know if you have "played" with a 120-300 yet, but if you are ever in Norfolk before you buy one, you are welcome to try mine.

The canon 1.4 TC won't fit my sigma 7-200 F2.8

Thanks for doing that little test for me Good to know that it does work then.

Haven't had my mitts on one yet, might go and try one out at Park Cameras next week. Probably a dangerous thing to do :bonk: Very kind offer though and I will bear that in mind, thank you

I use a Canon converter on my Sigma 300 f/2.8 and it works fine. I prefer the pictures with it to the Sigma one and will probably sell the Siggy soon.

I believe the 120-300 is based on the 300 prime so that is as good a recomendation as possible, thanks
