guys any info regarding 18-250?
which is better, sony or tamron?

Someone.. I forgot who told me not to buy 18250. The fella says its soft. He said for best IQ use 1855 and 55200 rather than 18250

Sony better. Looks better - more sexy and focusing speed a little faster. I should know, I owned that lens for about 1 year plus.

k thanks.. if like that.. maybe i should funding for UWA..
since it's not in my line up range.. but still can't decide which to hunt..
hearing about gear stripping.. takutnye..

I'm the fella, just sold the lens...

if quality of photo is not a concern, 18250 giv great travel lens, no need change lens often..
if quality is important, don't consider buy lens with zoom factor greater than 3x

18250 was my first lens. loved the af and lens lock. i think it's a very good multipurpose or travelling lens. it's quite sharp, i'd say. it's an all in one lens, kind of.

anyone is into fisheye here? it's a fun lens for less serious images and really tempted. i would need a lot more advice on them distortion-beauties.

Pros and cons of the Sigma 17-70mm OS HSM

Pros:

1.HSM - silent focus, really useful in capturing video as AF noise will not be recorded as it is not present.

2.Very short MFD (Minimum focus distance) - 22cm. So you could practically take close-ups of pics and be creative. (p.s. Its a really good camwhore lens LOL!) Tamron 17-50mm has a MFD of 27mm and the Carl Zeiss 1680z has MFD of 35cm.
Albnok also refered to it as Sigma 17-70mm OS HSM "Macro" due to the short MFD and the long zoom which enables amazing close ups!

3.Built in OS - According to some reviews by people, the built in OS in the lens offers 1-2 stop extra image stabilization compared to the SSS in the Alpha bodies. It also offers stabilization in the view finder

Cons:

1.No constant aperature

2.Price (if compared to the Tamron 17-50mm)

yup thinking of 1 lens on the go.. for casual btw..
but if suffer IQ.. casual also no fun..

actually when they say the IQ is bad...if you are not pixel peeping all the way..it isn't much of an issue la...

there you have it the answer yourself. which other alternative do you have aside from the tamrom counterpart? sony is tad better than tammy's as shootkk mentioned, quality wise and if not mistaken the af speed as well.

i dont get what 18250 IQ suffering talks is all about? can anyone care to fill me in?

i recommend the 16-105 a budget full walk around lens...... but now I am walking with 10-24.....uwa is poisoning, but some of my shots too much at 10mm, feel so dizzy now

Ps: I think iq suffering is more referred to things like softness at full open aperture, blurred sides, etc (purple firinging/ca counted??).... normally happen at full open aperture, but i think it can be solved with stopping down but of course u need slower shutter speed if ur in a not so good lighting which can cause handshake issues

the pictures from the 18-250 is definitely usable la...otherwise sony/tamron won't be manufacturing these lenses liao...

oohh.. yes, softer at max optical zoom at hinges. but hey this is from 18250 @ 30mm f4

ahtiven, looks ok without pixel peep, center sharpness on the net thingy looks spot-on.... but i guess softness can only be detected if someone used wide open aperture and group shot (u can see the ppl at the sides all soft-ing out.,... but softness happen to all lens though, even my 24-70 also same, i have to step down 1 stop

worst on my 10-24 now i constantly use around f4.5-5 (unless i need the wider aperture)

soft tak??

I also want....

"WTF you looking at?! "

zstan : most probably will go

eddybeh :my hands tremble pretty bad also , this 2 pic is the best i could get out of 100+ pics . better use support stabilizer (tripod , monopod)

hiansitt : yup no crop

Codyx : if u wait and wait , more will come (a77, etc) , then more tougher choice to make . so buy buy buy now

yuhi : if im not mistaken, u need to turn off SSS to get better output with OS lenses.

The Tamron lens really sucks at Video with AF....even the motor sound was recorded....perhaps MF?
