I was playing around with my newly acquired Minolta 300mm f/4 and 1.4x teleconverter-II with my Maxxum 7 film camera and noticed that the AF assist lamp doesn't work with this combo. Mounted a 3600 HS(D) flash to see if its AF assist lamp would work but it also didn't. Can anyone please confirm that this is normal behavior? Can't seem to find any documentation about this on the internet. I don't have a manual for the teleconverter.

Anxiously waiting for my 7D to come back and TIA,

Nevermind, I found the answer in the film 7 manual:
"The AF illuminator may not operate with 300mm or longer single focal length lenses." - page 59 of the Maxxum 7 (english) manual.

That's what I was going to suggest having looked at an 8000i manual which says 210 max.

A little OT. At one point I lost a Minolta lens cap and almost immediately found a Canon or the same diameter. Which elicited more than a few comments questions from some folks about using a Canon lens on a Minolta camera. I can imagine the reactions of those few sharp enough eyed folks that will spot a Canon lens on a Minolta. (Tell them it's a secret test-bed camera?)

   I want to thank you ECCL. I recently purchased an 80-200 HS lens and had no clue as to what teleconverter to purchase. After reading your review I went out and found a Kenko 300 2X and it works flawlessly. Thanks.

You got it. I just came back from Point Reyes Nat. Seashore in Northern California. I figure I'll read up as to how to post on Dyxum.

    What a great source of information!

Will the Minolta TCs work with the old 80-200G lens? I thought I had seen it listed somewhere, but now I can't find it anymore.

Thanks for your help.

Picking up on Ballfresno's thread regarding body/lens converters I have just got a Maxxum / PK converter for some of my old lenses.

So far I've been pretty gobsmacked with the results - much better than I was expecting!!!

Will post more details soon.

quick question, what would be my best bet for a TC that'll work for both Sigma 70-200 EX DG and Minolta 300/4 G? With decent quality?

You can use Sigma EX or EX DG converter (1.4X or 2X) or you can use Kenko Pro 300/Pro 300 DG or Tamron SP 1.4X or 2X.

I'm not sure whether the orignal Minolta TC will fit the Sigma but it will fit Minolta APO 300/4 G for sure but it is much more expensive than Sigma/Kenko/Tamron.

for tc's without rom chips, do they compromise AS? AS needs focal length to properly shift the CCD, so wont having the wrong number mess things about
there's nothing worse than a sharp picture of a fuzzy concept. -a. adams

If a TC does not have rom chips, it is basically a pass through, the camera just ignore the TC and just get the information from the original lens.

AS will still work but probably not as effective since the camera does not know the resulting focal length. I believe Kenko Pro 300/Tamron SP/Sigma EX 1.4X TC are just pass through but the resulting images from 70-200F2.8 or 70-210/4 + 1.4X TC seems to be fine.
