Tamron 70-300 or Beercan?

Yes
I have a Tamron 70-300 which I bought thinking I needed it for low level miitary aircraft in the Loop and for animal close ups at the zoo / wildlife.

Having spent last Monday at the Loop and seen some great activity but missed several shots due to the woefully slow focus action of the Tamron, I'm wondering if the Beercan may be the better option.

I'd miss the extra length for animals but now realise 200mm is adequate for the jets.

I gather the quality of the optics on the Minolta is superior

Question (for Beercan aficionados) - is the focus action fast enough for a jet at 500 knots?

Thanks.

focus speed is a 2-part equation - 1 is the AF speed of the body & 1 is the speed that the lens can change focus at.
Neither the A300 or the Tamron 70-300 LD Di are stellar for AF speed.

In your case if you can afford £300-350 I would be looking at the Tamron SP 70-300 USD.
If you can only afford £100-150 then the beercan is worth looking at.

The Tamron 70-300 VC USD is a superb lens, you should be able to pick it up for £280
 
Lowfly aviation photography is challenging at best, yes on a good day where the light is wall to wall, you could even get away with canon's dreaded 75-300mm, but conditions are rarely like that and a fast lens is the order of the day to keep those shutter speeds high without maxing out on the higher ISOs

The problem is due to the light and shadow, achieving the fast enough shutter speeds you need a minimum of an f4 lens to continued to get images when conditions start to fall off. As 300mm is standard for most locations, unless you get swamped by the F15s a sigma 100-300mm f4 or 300mm f4 prime would be better suited to you needs.

So in answer to your question, neither lens is really suited
 
Thanks for the replies. Food for thought.

I had a 28-200 which I used previously. I had a reasonable image of a Tornado which led me to think a 200mm might suffice, particularly as I was having to reduce the focal length on some passes.

Still wondering about the Beercan though

The F15s and Tonka's will fill you lens in certain locations, however most of the locations especially for the typhoons and hawks require 300mm.

Whats your budget, I assume as you're talking about the beercan, your budget is less than £300?

Correct. Any purchases need to be below my wife's radar, hence me considering the beercan!
