Tamron 17 - 50mm..... To me its pretty sharp, totally satisfied.....
here a sample of 17-50mm tamron wide open at f2.8 colours are as they are no PP only resize!
i must say its a sharp and need glass.
It's something about the background bokeh.. Just seems a little.. I don't know how to put it.. wierd? harsh? :dunno: My 18-200VR has a similar kind of bokeh also.. It's just not pleasant. The background bokeh of the Nikkor 17-55 seems more pleasant but the price hurts.
It's all about "Expectations". When we pay less to get the Tamron, do we really expect to get IQ on par with the Nikkor? Personally, Hell NO! If it really is the case, Nikon's version would have been out of the market long ago.
I am suspecting that Nikon kit lenses have some part to play in this. Nikon kit lenses are pretty decent and produces reasonable images at the widest aperture throughout the entire range. I believe Nikon deliberately made it a point to do so. So for someone moving from using kit lenses to the Tamron, he would have expected the Tamron to produce 'tack sharp' images at f2.8. Unfortunately, that's not the case. I own the Tamron and acknowledge that at f2.8, the images can be a little soft but the images are still usable by my standards.
Then the whole argument about paying more to get the Tamron only to use it at smaller aperatures ie f4, f5.6 comes in. Well, personally, i paid the extra to have the added option to shoot at f2.8 when there is a need and i know (and accept) that the IQ may not be on par with the Nikon's equivalent. Frankly, if i didnt want the extra option, i would have stuck to the kit lenses which are known to be value for money.
Just my 2 cents..
No offence, but I think the Nikkor 17-55DX is capable of getting something much sharper than that at f/5.6.
My opinion of 3rd party lenses has never been good because they are usually only good after stopping down a couple of stops. My opinion is that if I buy a f/2.8 lens, I want to be able to get good images at f/2.8, otherwise what's the difference between a 18-55 kit lens and the f/2.8 lens other than getting a brighter view in the VF? ;p

Hi
Your 2 cents make a lot of sense ... :thumbsup::thumbsup: .. I totally agree.

Yes. The Nikkor 17-55 is not something I would like to carry if I'm travelling light. For the bokeh, I think it's pretty much the optical design and should not have anything to do with the lighting condition. ;pyeah.. i get what you mean. maybe was the lighted condition? I aint carrying the 1755 with my S5 overseas haha way too heavy !!
however, i was wrong about the nikkor's compatibility with FF. apparently it can be used from 26mm-55mm. not bad! the tamron completely does not work on FF
yeah.. i get what you mean. maybe was the lighted condition? I aint carrying the 1755 with my S5 overseas haha way too heavy !!
The Nikkor 17-55mm is arguably the best walkabout Nikon lens for DX cameras. But, the price is very high and bros who had bought it new from the shops will lose a lot of money (about $1,000) when they decide to sell this lens in future. For the Tamron 17-50mm, most users have nothing but praise on the image quality, and sellers only lose about $100 selling it later. Image quality wise, Nikkor is the winner. Value for money wise, Tamron is the winner.
