A couple of attempts that were rightly rejected( I wanted a decond opinion). Has anyone ever had success when using a teleconverter?

Thanks,

Dave

Sure! But you question is a bit vague. Big difference between a off-brand teleconverter on the front of a digicam vs. a Canon 1.4x teleconverter on the front of an L-quality lens.

I used a converter on a digicam (Canon A80) often back in the day (2 years ago :) ) and it could work well if everything was perfect. Lots of trouble, however, although masked a bit because of the limitations of the A80 itself.

I would happily use a 1.4x (Canon, Kenko) on my 20d if I had one, with suitable lenses (i.e., not to extend my walk-around lens but yes to extend my tele).

It's a Phenix 2X that I got for nothing on the internet. I know Sigma makes one as well as Sony, but Sony's is $900. For that I might as well by a 500mm zoom lense, which I'm also considering. The camera is a Minolta 5D from which I've had some pretty good results. Have you heard anything one way or the other about Sigma' 50-500 zoom?

Not to be harsh, but you got what you paid for ;)

I often use a Canon 2X converter with a 70-200 2.8L with great success.

I don't have any personal experience with the offerings from Sigma, Tamron or Tokina. Some of the online photo stores such as B&H photo & video have user comments which can be helpful.
Edited to add:
When using a converter it is almost mandatory to at least use a monopod, and preferably a tripod.

CheersThis lens is often referred to as the "Bigma" and is well liked by most that use it. I can only go on what I have read as I don't personally own one. This lens is a serious bit of kit. It's big and heavy so I hope you've got the stamina to lug it plus a sturdy tripod around all day.

I just wonder if you would be better off with a 70-300 lens and a 2x teleconverter for the times you do need that extra bit of reach.

Here are a couple of links to some reviews.

Thanks for the links Christine. Still debating what to do.

Phoenix products will always be available cheap on Ebay because people try them once & then sell them instantly. They're junk.

Regarding a long zoom, I opted for the Sigma 80-400 with Image-stablilization over the 50-500. Unless you plan to use a tripod exclusively at the long end of the zoom, I'd highly recommend getting a lens with IS.

With that said, I should mention that the 80-400 is a bit of a slow lens, so it's not always an ideal train lens. It's fine for slow moving steam engines, but I put it away when shooting Amtrak trains.

Good luck,
Bill

thanks Bill. I've got a Minolta 5D so the stabilization is built into the camera rather then the lens. I also plan to use it on aircraft, and the extra 100mm might come in handy. I've heard a lot of good things about the 50-500.

Cheers
