Hi everyone,

Thanx for your comments and pictures. Your input, along with reviews I've read elsewhere, have helped me make the decision to get this lens.

Hi everyone,

Hehe, i have decided to get this too. I was deciding between the tokina 11-16 or this. Both seems equally sharp to me. Im jus a newbie. But prefer this due to the affordability and the finishing of the lens.

Now saving up abit more before i plunge in. I have not seen portrait shots by this lens so far. I read that uwa lens gives a very funny perspective on portraits like the head will be super big if taken at close proximity.

Anyone has any sample to show?

I initially narrowed my choices to this lens and Canon's EF-S 10-22mm lens. The impression I gathered from reading several reviews is that they're pretty close, with the Canon lens having a slight edge in image quality and the Sigma coming out ahead in build quality. Looking at the pictures posted here (and elsewhere), the Sigma looks more than capable.

In the end, what swung it for me were two additional factors:
1. price - the Sigma costs about $300 less
2. warranty - I called Sigma and was told that local sets would come with a 2.5-year warranty (including the extra 6 months for registering online) vs Canon's 15-month warranty (including 3 extra months for registering online).

Few shots to share

Using Tianya ND filter with wide angle filter holder (and any P Cokin compatible), will give vignetting at 10mm

all taken at 10mm, f9

what a joy to use this lens

Nice fireworks~ #2 is great.

You can get the wide angle holder that has 1 slot. Otherwise can diy and cut off the 2 slots. Saw this from some forum about using the standard 3 slots for uwa lens. Otherwise, i think no vignetting at 12 or 13mm onwards.

Thanks azurebluee, mine is already the wide angle holder with 1 slot, and it still gives vignetting at 10mm. Anyone tried with 77mm b+w, will it give vignetting also?

Alternatively we can use cokin Z series. I hope Tianya will come out with its clone :bsmilie:

Thanks azurebluee, mine is already the wide angle holder with 1 slot, and it still gives vignetting at 10mm. - hmmm :think: The guys in the other forum removed the uv filter before mounting the p holder. So lens only holds 1 p series. I do not have the holder but this was what I have read so far.

Anyone tried with 77mm b+w, will it give vignetting also? - not obvious vignetting (I don't think there is any based on my untrained eyes). I used the b+w nd100 for the tyrsall house shot. If used with 2 standard filters, obvious vignetting.

Oops, I didn't remove my UV filter before mounting the p holder. Will try again later without UV filter.

Oceanpriest, Just take out your UV filter and you'll not get any vignetting. I am a pentax and 10-20 user, so I can tell you for sure. ;-)

10mm F11. Long exposure + blending with photomatix

 

[wrx_sti_22b]

I used to have one that was rather soft.

I used to have one that was rather soft.

Mine too when I first got it. Sent in for calibration and it was much sharper.

Any users here using the 77mm "normal" CPL filter not those slim ones? May i know if you get vignetting if shoot at 10mm?

Any ideas which brand to get? Hoya? B+W? Tianya?

And any ideas also how much the prices are btw any of the brands? I'm currently looking one for this lens...

Any users here using the 77mm "normal" CPL filter not those slim ones? May i know if you get vignetting if shoot at 10mm? --No vignetting if you are using only 1 normal (non slim) filter. For cpl on wide angle lens in particular, you may experience 'light fall off' or uneveness in the polarization of the sky. A short discussion here: http://www.flickr.com/groups/efs1022/discuss/72157604066637015/

Any ideas which brand to get? Hoya? B+W? Tianya? --I have used a basic tokina uv filter which gave me flare. I rarely use it now. B+W ND110 for long exposure. For Tianya GND which I will getting soon, from the contribution of hjbyeo and my research so far, with the wide angle holder (holds 1 filter only) no vignetting.

And any ideas also how much the prices are btw any of the brands? I'm currently looking one for this lens...--check from the shops or mass sellers which maybe more competitive than the shops.

HTH ;p

thanks azurebluee for your input,
right now don't know which one to invest in, either a tianya holder or screw-in CPL?

thanks azurebluee for your input,

While waiting for TS to revert, i've used both and prefer the P series holder (tian ya). I use screw in filters when on holiday- less accessories to carry around lah.

Pros for screw in
- no need to mount holder
- cpl turns much easier than P series
- you can use the filter with smaller diameter lens by getting additional step up rings. 62-77mm or XX to 77mm.

Cons for screw in
- additional cost for the rings as above
- additional cost incurred when you need ND 2, 4, 8 and others which do not come cheap especially for 77mm.
____________________

Pros for P series
- same mount can be used with other tian ya filters: Gradual ND, blue, red, ND 2, 4, 8 and other colored filters
- Like the screw in type, you can get additional rings for P holder for specific lens
- it will be cheaper in the long run if you get other P series filter

Cons for P series
- additional steps for the set up compared to just screw in.
- tian ya filters may chip at the edges if you are rough with it.
- additional cost for the rings to fit other lens.

These are my personal reviews after using these 2 kinds. Its your choice I guess.

Yeah, calibration is free during warranty period. I sold my copy months back. Tempted to get another one to play. :sticktong
