Tamron AF18-250mm F/3.5-6.3 Di II LD Aspherical (IF)

[calebk]

...
The latest digital camera mag had a review of wide lenses 11-18.
And they put Sigma and Tamrons 11-18 better than most of the original lenses, only Canons wide has a slight edge on image quality.
Sonys own 11-18 actually ranked as one of the worst.

...

Sigma has no 11-18.

Best distortion handling for a UWA zoom: Sigma 12-24
Best sharpness: Tokina 12-24, Sigma 10-20, Nikkor 12-24, Canon 10-22 (very close fight. all the above models perform very well here.)
Most solid build: Tokina 12-24
Lightest weight: Tamron 11-18

Highest CA levels: Tokina 12-24
Highest chance of getting a copy that's soft: Tamron 11-18 (some copies of this lens have been found soft, even at f/8)

Haven't read much about the Sony 11-18...

My take on the third-party vs. original:

If the original manufacturer produces a lens that either exhibits far-superior performance or has no equivalent within the third-party manufacturer's catalogue, then get the original.

Should the third-party manufacturer come up with a lens that the original manufacturer does not produce, or produces to a mediocre standard, then I would go for the third-party product.

dont buy a third party lens...such a waste of money. save up and get the original.

Care to elaborate on your statement, that you make with such conviction?

checked with mscolor...
they selling @$710 but i guess it's not the best price yet.....

wondering if getting either 50mm f1.4 or 28mm f2.8 (both by sony) and maybe 75mm-300mm lens will be a better investment...:think:

For that price might as well get sigma 18-200 OS... the OS is much much much more useful than the extra 50mm...

250mm @ max aperture of f/6.3 is too limiting for my liking. Need to maintain high enough shutter speed to prevent motion blur and having a small max aperture.

Sony have SSS (anti-shake sensor built in), so don't need the OS

If you don't mind changing lens, prefer more portrait or low light shots and look more into better quality of the image, then probably. 50mm f/1.7 will be a cheaper option compare to f/1.4.

however if you are looking into a all in one lens, 18-250mm is the way to go. Or add on a 50mm lens just for portrait and low light shots.

50mm f/1.7? any brand? any idea of the cost?

minolta lo.. haa. cheap

minolta, 2nd price range from S$140-200 depend on condition, can be found in B&S.

mmm.....sounds a lot cheaper than a new 50mm f/1.4 but what is the difference in the max shutter speed between the 50mm f/1.4 and 50mm f/1.7?

that is a lot deeper...haha....

but the difference in shutter speed is really just one stop, rite?

hmm.. that i not too sure le... i know its a faster lens n sharper iirc. but then have to ask our pro bro

f/1.4 and f/1.7 are about a third of a stop apart.

Full f/stops are as follows:

f/1, f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22, f/32

f/1, f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22, f/32

so that means the impact on the achievable shutter speed between the two prime lens are like a third of a stop difference (if shutter speed got 1/3 stop diff?) :think:

Actually it's 2/3 stop, between f/1.4 & f/1.7, there's another step of f/1.6, don't know how they count one :sweat:

mmmm.....ok....all these calculations are giving me sweaty palms...:sweat:

now i am considering between this lens and the tamron AF17-50mm F/2.8 (i think it starts from 17). both abt same price and dec is coming = bonus coming......

wondering if i should get the travel lens or the "fast" zoom lens first?:dunno:
