sigma 1.4 converter & 70-300 apo Q.

[Dead Dog]

I'd like a sigma 1.4 converter to go with my sigma 70-300 APO DG macro, does this work with it? i've checked compatibility but it doesn't show that lens

anyone here use that combo. do i have to make sure it's the APO converter, as opposed to maybe older versions?

also do you loose too much quality using a 2x?

I have a 2x TC and I beleive any lens will work with it, potentially.

I coudl be wrong of course, but i think you may just lose autofocus, and a stop or so light and some sharpness

If you can wait till later, i will take a pic with and without the TC today while I am out anbd let you decide yourself

Ok i have taken a quick pic in my kitchen for you.

I am sure you coudl get better results in the correct situation, but I think this will do for this "test"

Please note, my lens is an old sigma II 4-5.6 that has the aperature ring on the lens itself. and I lose autofocus with the TC

both shots were from the same place, which was abotu 7 foot away from the subject and both with the lens at 300mm.

Neither picture has had anything done in PP other than resizing for the posting


NO TC

and with TC

I hope that helps, I am sure the light could be sorted with a simple levels adjustement

thanks for that
it'd mainly be used up santa pod, so light would be a lot better anyway, but then i guess 99% of anyones use with a 2x tc would be out side
