Would my Sigma 70-300 APO DG MACRO f4-5.6 work with a 1.4x or 2x TC?

So then would my Would my Sigma 70-300 APO DG MACRO f4-5.6 work with a 1.4x or 2x TC?

IT is much cheaper than buying a bigger lens Plus it will keep me going until I get the 100-400 L lens

Thanks

Unlikely, the Canon AF system will shut off after f/5.6. A Kenko TC might still AF.

IQ will not be good.

 

[Matt Sayle]

Thank you Puddleduck I will keep my cash and save up for the 100-400

It won't work or if it does you'll hate it, use it once and never use it again.

If you want a stop gap get a Sigma 100-300 f4 EX. FL is about right for most circuits and its a stop faster than the Canon.

I want more length andrew. I am getting into Bird photography atm and I want a bigger lens for that!

 

[andrewc]

the 100-300 will take a t/c turning it into a 140-420 f5.6 but AF is a bit slower and there is some IQ degredation

 

[Matt Sayle]

Ah I get ya

The question is, is it worth buying that lot or keeping my money and getting a 100-400?

No it will not. I have the same camera and lens, and tried the lens with it. No af, but also in manual focus, you do not even get the little green light to help you focus.

Although a great lens remember that with the TC you will lose AF with the 100-400, you need to focus manually

I am not buying a TC. I am going to save up for a 100-400 instead of

Matt I have Kenko x2 con, my advice save up for a longer lens, their useless, no af on my 70-300mm, so manual focus only, by time youve focused youll have missed your shot,IQ is not that good in my opinion
