    Posted: 11 July 2007 at 22:21
I have just picked up this lens to use on my a100 after previously owning 2x 7xi camera with xi lenses.

I hope to get some great shots with this lens but have 2 questions if any owners of this lens can help.

1. How is depth of field adjusted as I have heard that results are better a step or two down from f2.8 but cannot see this adjustment on the lens. I only got it today and there was no manual with it.

2. Is the Kenko 300 DG Pro a good addition in either 1.4x or 2x ? I was originally thinking of getting a Tamron 200-500 or Bigma but thought this Tokina with a Teleconverter would be of more use.

Hope some people on here may be able to help.

Thanks in advance,

Matty

Same as on your 7xi; rotate the dial on the A100 to adjust shutter speed & aperture. Of course, you pay good money and tote a large lens to have f/2.8 in the first place; if you want to shoot stopped down, you could have bought a beercan (70-210/4). Stop down when you can but don't hesitate to shoot wide open when shots will benefit from faster shutter or lower ISO; they may not be as sharp as with the Min 80-200G but go for it anyway.

If either, I'd try the 1.4X ... but if you're stopping down to f/4 or so for good sharpness, you're getting f/5.6 at best with the TC (or f/8 with the 2X) and softer results. It would be great to try one out; if you compare shots with the TC to shots without the TC, cropped to match, then upsized, you might find it a close enough contest to not bother with the TC. Matched APO TCs for top notch lenses work; TCs on consumer lenses not so well ... you're in the middle with a 3rd party APO lens and a mismatched 3rd party APO TC ... hard to say.

Thanks.

I only really used my 7xi on Auto but now I have a good lens and quicker/easier viewing of results on the a100 I can experiment. Not used it properly yet.

I did take some good photos with the 7xi and its 100-300 xi lens on Safari in Masai Mara. Was thinking about getting a Bigma or 200-500 Tamron for my next trip but hoping the Tokina with 2x TC can acheive similar results, less lens to carry that way.

Nice to see another new poster (quite a few recently..)

It is a good point that working with digital encourages you to expreriment (which I think is a good thing), Welcome to Dyxum!

Thankyou.

Found the website very helpful and always wondered when I was on Safari why my little 100-300 xi lens was so much smaller that other peoples 300mm lenses. A little reading goes a long way.

And with ease of Digital I cannot wait to see instant results and a higher learning curve.

Loving the Tokina lens which I picked up on ebay for L250. Quite chuffed compared to Sony Minolta 80-200 f2.8 lenses being considerably more expensive and quality cannot be increased by the same factor cost is.

Now just need to find a wide angle lens to compliment the Tokina. Zeiss 16-80 seems to be getting mixed reviews for its cost, which is L395 in UK cheapest I have found. Sigma EX Macro 18-50 f2.8 seems to be quite new and although it is getting favourable magazine reviews, I always wonder if advertising has anything to do with those and the Tamron 17-50 f2.8 is another option. Unless I can live with a 24-70 f2.8.

And then for Safari I am looking at a 2x Kenko PRO DG TC which seems to be the best match for the Tokina on reading the TC article, or maybe a Tamron 200-500. TC is certainly a lighter option !!!!

And I thought my Sony would utilise my old xi lenses. Now I know more about them I am flogging those with all my other old Minolta 7xi bodies and accessories. Hopefully get some money towards some nice new stuff !!!!

Welcome.

There's a Sigma going here and if you look at the review mentioned with a link it seems to test extremely well.

If I needed a lens in that range I would give it serious consideration and it fits your needs well with a gap of 20mm -- but that can be a matter of a few steps.

I would like to know if anyone has tried out this lens on a KM 7D?
If so any comments would be appreciated!
How does it work with 2x and 1.5x converters? Hows the focus speed and accuracy? Does it maintain sharpness with the converters?

What would be a normal price on this lens, in USD? I've seen suggested as low as 500-600 USD.

Thanx!

I've the older version, the non-pro: Tokina AT-X 828 AF 80-200mm F2.8.
Focus speed of the Tokina is slow on the 7D compared to the 7, so a A700 would be a bit improvement.
The Tokina is soft until +/- F/4. I've used the lens with a 1.7x TC, but i broke the AF in the TC. TC makes the lens AF slower.
I think around 500 USD would be a normal price, I paid 370 euro.

you got a great bargain!
tokina makes fine optics with tank like build quality. be warned, good built lenses are very addictive!

as a outdoor travel companion, i'd suggest the CZ 16-80. for more mixed type of shooting (street, social, some lowlight, indoors) tamron 17-50/2.8 is quite well regarded and its speed matches your f2.8 telephoto.

apart from those, sigma made a (rather bulky) 24-70/2.8 zoom, a little less wide but goes up to 70mm. finally there is KM/Tamron 28-75/2.8, very well regarded but not wide enough for wide angle shooting.

Consider your shooting preferences before making your choice:)
