Lens test?

[Lostkat]

I've just bought a Tamron SP AF 17-35mm Tamron F2.8/4 LD with part of my yearly bonus to replace my Canon 300D kit lens. Ideally, I would have liked the Canon 17-40L, but I just couldn't justify the cost, so I went for this one instead.

I've read many excellent reviews. It's supposed to be a vast improvement on the kit lens, and an all round sharp lens. The only issue seems to be Tamron's variable quality, which means that getting a sharp one is a bit hit and miss. I spoke to the guy in the shop about my concerns, and as long as I return the lens in perfect condition, I can get a refund.

Anyway, I would like some advice on how to put this lens through its paces and compare it to the kit lens. I've taken a few shots indoors, but the lighting is so poor that the photos look terrible on both lenses. I'll probably need to do it outside. Any suggestions/links on what shots I can take to test various aspects of the lenses - sharpness/CA etc.?

Thanks in advance

If you really have to do the test tonight then setup some good indoor lighting and photograph real objects at F2.8, F4, F5.6 and F8. But they are wide angle lenses so ideally I would until tomorrow and test with landscape shots

Also, as you are testing sharpness you should be using a tripod, mirror lockup with self timer.

Yeah, I knew this was the best solution, but was just being impatient Just going to have to wait for daylight. I can't be bothered to set up the studio lights just for a test, and I will be using it for outdoors shots most, so I should test it as such. Mirror lock-up, tripod etc. goes without saying. Thanks for talking sense

Will also test on the chart dod linked to.

Thanks for the comments/advice guys.

Thanks for the tips

I was trying to think of things I could photograph in the garden with sufficient detail. There's not really much in the immediate area that I can do though. I might have to venture further afield. Perhaps down to the canal where there are the barges which have signwriting etc. on.

Trees against a light sky was already in my plan, as it's what I've had issues on with the kit lens before.

OK, enough of the bickering please.

mods I think we need a beginners FAQ which gives answers to regular basic questions.

What an excellent idea. It would add on nicely to the SLR buyers guide in the FAQ. I take it that you're volunteering yourself as composer for this?

we toyed with the idea of a beginners guide, but that would take away a lot from the forum IMHO, i think it would here too. No question is a stupid question if someone learns something from it!

I agree with you matty. I would hate to be on a forum where you get flack and rolleyes for asking a "silly" question.

I also disagree with the comment that these forums are going downhill. I have always found this forum to be populated by a huge mix of helpful people. Never before have I seen someone roll their eyes at a genuine question regarding lens testing until now. It saddens me somewhat.

Then submit to the FAQ. I would be only too happy to add stuff to the wealth of already useful information on there
