I think one of my questions is hidden somewhere in the Forums but as sure as hell I can't find it
Q1...As a lens to slot in between a 17-35 & a 70-300 which of the following would be appropriate
Sigma 28-105 f/2.8-4
Sigma 28-135 f/3.8-5.6 Aspherical
Q2...Sigma converter for 70-300 APO DG macro
1.4 EX DG
All of the above are on the EPZ shop site

Q1 - Any of the two lenses would be appropriate, I suppose it depends whether you need the extra length, ot the wider aperture.
Q2 - I wouldn't recommend using a teleconverter with that lens at all.
With the 1.4x your max aperture at the long end will be f/8
With the 2x your max aperture at the lon end will be f/11
Hope this helps.

i find the forun search function not nearly as good as it used to be, and while i'm griping, the search function in the readers gallery still limits the results to about 20 still.
Q1. Neither, get a canon 50mm f1.8, you don't need another zoom between the other 2, just use your legs. It's cheeper and image quality is vastly superior in everyway.
Q2. Can't recommend any to go with the 70-300, you will strugle with having to use MF, and loss of quality will be significant.
Ill second that ! a bit of shoe zooming, the 50mm is well worth the hassle of no zoom, so sharp and so fast
nice to see someone on here knows what they are talking about

Please take a look at my portfolio, theres plenty of shoe zooming going on there!

Thanks all for the info...
Looks like it's going to be the 50mm f1.8
Wonder if the EPZ shop has them in stock?
Q2. None. They don't fit!
I would recomened a new one because if some burk leaves the end cap off they can attract a lot of dust that gets trapped inside, so caps on at all times when not in use and it will last years and years!
Should have no problem getting one, but if you can try and lay your hands on the older Mk 1. Optically the same, but better build and better MF ring. Second hand Mk 1's are more expensive than new Mk2's (around 100)
This one on e bay finishing in just over an hour.
Would you please clarify something for me Ian
On a previous thread you stated
Quote: Many of Sigma's lenses don't work properly on converters other than their own. Having said that, I have a 120-300 with an EF11 1.4x on and it works fine on a 300D and 1D!
Is it the particular lens I have that is the problem ?
Yes, your lens is an APO 70-300 which is not on Sigma's list of compatible lenses. The converters will not physically fit on the lens.
Hope it helps.
Thanks for the info Ian....It was only a thought...
i am using a Tamron 2X converter with the siggy 70-200 APO if that helps?
Q1. I'd go for the 28-105 because of the extra stops. Better in low light & more control.
Q2. None will fit. I have a x2 and a 70-300mm. At 70mm the back of the lens hits the front of the converter. Other than this you will only get manual focus.
If you want a longer lens, you'll need to buy one.
