This afternoon I bought a new lens. It's the replacement for the Sigma 18-200mm zoom that I already have. The new one is the 18-200mm f3.5-6.3 DC OS. "OS" stands for optical stabilizer, and with this lens it's possible to shoot with a shutter speed 3 times lower than normal for any particular focal length.
Note that this is 154mm in the 18-200mm range, which equals 246.4mm in 35mm format. Shutter speed 1/40th of a second! I was a lot further away from them than it appears.
The lens is actually totally redesigned, and is a bit longer and heavier than the old model. The unfortunate part is that I had to buy a new UV filter as the diameter is larger, too, because the front element is now wider.
Now my "all in one carry around lens" is even suitable for very low light shooting, as shown in this shot, which is one of a series I took tonight while I was still in the city centre.
There's always a lot of activity there on Thursdays because it's late night shopping till 9pm. This is in Pitt St Mall, (which is closed off to traffic), and I've seen this guy around a few times before, but have no idea what's behind all of this. I did see one girl go up and get a quick hug. I, myself, kept my distance and started shooting. The guy on the right (the actual "hugger") became aware of my presence, and obviously didn't mind at all, so I guess you could call this a semi candid.

Cool 'semi-candid' shot Andrew, seems like I could try that lens as well, I will take it into consideration, =)

@Alfredo J. Martiz J.: Thanks, Alfredo. For me, it does an excellent job -- as did its predecessor -- but it's taken things to a whole new level with the optical stabiliser. In reviews on the Internet, it comes off very well for a zoom with such a tremendous range (11 times).
very funny shot ... nice B&W too

@Me 2: Thanks!
Really nice candid shot Andrew! Congrats on the new lens! I really love my Sigma 55-200 mm D. I guess I could have done with the OS version this evening when I went outside to shoot the rising full moon. What I wanted was a shot with the sky (still not quite dark) and framed with a tree branch. But on the lower shutter speed required for the latter shot my hands/arms would just not stay quite still enough tonight. So I ended up with a spot metered shot of the moon (detail on the moon) but nothing else visible. Sure could have used the OS. Your photo has a great tonal range for the time of night, and very little grain with that ISO!! :-)

@Anne: Thanks for your comments, Anne. I'm not at all surprised that you enjoy your Sigma lens, after my experiences with this brand. As far as my photo's concerned, I put the tonal range down to the fairly good lighting in the scene, the lens itself and the use of the highlights/shadow filter in Photoshop, followed by the channel mixer for the black and white conversion.
My little trick for getting almost totally rid of noise at 1600 ISO, is to convert from RAW using BreezeBrowser Pro, with the noise reduction filter on high. This is not the most convenient converter to use, because if you want to batch convert, making individual adjustments to each file, you can't do it. You have to adjust one file, wait while it converts, then do the next one. You can only batch convert if you use exactly the same setting for all files. For the moment, then, it's a very useful tool for high ISO shots, but due to the above limitations, I unfortunately cannot recommend it without reservations.
PREVIEW ONLY
