Default Trying new lens

Just got Tamron 17-50mm f2.8 recently so I took some photos of my wife and kid. First impressions are positive. Even at f2.8 it's sharp if you get focus right, at 3.5 to 5.6 it's just brilliant. Don't have too many f2.8 photos because DOF is very shallow and my kid is too fast to catch him in focus .
From few photos I've taken at f8 and higher it seems it's not so good for landscapes, it get quite soft over that aperture.

RAW f4.0 1/500 50mm external flash. Some exposure and curves adjustment. Resized in IrfanView with sharpening. I know the background is distracting but I haven't finished my garden yet

Ps: Going for two weeks holiday to Greece so you can expect some ladscapes when I'm back and have some time to process them

Great photo! Thanks for sharing it. You mentioned "external flash"!! Always glad to see someone making "good use" of their flash! Really neat work here.

I always use external flash when shooting portraits outside, that's why I asked my mum to buy it for me for birthday . It makes a world of difference.

That's a lovely family shot Greg. Have fun in Greece - wonderful country.

Interested to hear about the 17-50 and I'm debating that, the older Tamron 28-75 2.8 or one of the Sigmas 17-70 2.8 - 4 macro, 24-70 2.8 macro or the older 28-70 2.8). Difficult decision, the Tamron 17-50 seems to get the nod for portraits but the Sigma range seems more usable (I have the lower end covered by two other lenses).

Glad you are enjoying the lens. At f8 there shouldn't be an issue, and after f8 it would be expected that a lens on an APS-C body would get softer. If you have unusable results at f8 then I would look at getting it changed.

Forgfish, if you don't need the wide angle then I've been happy with the Sigma 24-70mm f2.8 (original), well I wasn't happy with the first copy but when I changed it the 2nd was good. I really don't use it much, actually I've never shot with it in anger as it is my backup to the Canon 24-105mm f4 L so I like to have it ready to go on a body at weddings. I take test shots from time to time to ensure there are no issues. I really should give it a good run at some point when I'm back in the UK to put it really through its paces.

I agree with mark here. My main product photography lens is the Sigma 24-60 2.8 ex lens. It has very close focus, about four to six inches off glass so is perfect for small products, but wide enough that its great for large products as well.

I read reviews upon reviews deeming the 24-60 was much sharper at corners than the 24-70 version and was also sharper at long end (although not as long) but and they were both sharper than the tamron 17-70.

I was ready and willing to purchase the sigma 24-60 or 24-70 but I found the sigma 24-60 first and fir a nice price.

Im extremely happy with it, if you are interested I can post some pics I took with it.

Edit: it also make a gorgeous portrait lens, and excellent landscapes, but I do prefer my primes with landscaping, not really so much for the sharpness because this lens is incredibly sharp, just mainly because of the unrivaled coloring Ive seen out of my CZ glass. although the sigma comes extremely close, which says alot for a zoom lens to hang in there with the big boy primes! Also, My favorite portrait lens is my cz 200 2.8, but I interchange between the 200 and the sigma 24 60 depending on whether im shooting close or far. 24mm is wider than you think, especially when it close focuses, youd be surprised. for example, I can stand about 6-10 feet back from a car and get the whole thing in frame, (a classic pontiac grand prix full size sedan for example) with pretty much no distortions, I cant see why youd want anything wider unless you're looking for that sigma 10-20mm look

I do have sigma 10-20mm which I use for landscapes, I just wanted something to replace kit lens for taking photos of my kid. This Tamron is great for that, much better than the old kit lens which came with my DL2.
I didn't say it was terrible at f8, it's just a bit softer than my sigma 10-20. But since I intend to use it mainly as portrait lens that's not a big deal.

That's good, and sounds like you have a good 10-20 as well, some are not the best, mine is OK but not great, however I allow for it as I like the angles.

When I got my sigma 10-20 it wasn't good at all, one side of the photo was blurry while other was fine, like it was decentered. Sent it to Sigma UK but as it was gray import they had to send it to Japan for calibrating. Came back after 5 weeks with letter saying that there's nothing wrong with it, they just reset the chip or something, didn't charge me anything. Funny enough photos were OK after that, strange.

Yes, I think I'm definitely veering towards the Sigma 24-70 2.8 (the macro version). Seen it on-line here and will check it out at my usual dealer next week.
