Good lens........2007-04-19

The lens appears to be well made and finished and comes with a hood and HSM which is fast and quiet and allows manual override in auto focus mode. The 30mm designation equates to 48mm on an APS-C Canon DSLR with a "crop" factor of x1.6 and this makes it roughly the equivalent of a 50mm lens on a full frame camera. The aperture range is f1.4 to f16 and in my opinion the f1.4 is useable and comes in handy for indoor low light situations (I recently took some shots of a new baby and I didn't want to use flash and I'm happy with the results) as well as for shallow depth of field use.

All in all I'm very happy with this lens.

Note though that this is a DC lens and that it's suitable for APS-C sensor cameras only.

Can't recommend this enough.......2007-05-18

I have a family and do lots of low light indoor shooting and spent many months trying to track down a suitable f2.0 level lens. There's no zoom on the market that's really right, I considered the nikon 17-55 f2.8 but at £900 its expensive and F2.8 is less than a full stop better than my kit 18-135 wide open. So not much gain there really.

So I bought this, never had a non zoom before so was very hessitant, but I shouldn't have worried. 30mm is a really good compromise focal length, and I can frame shots exactly how I want (okay, I sometimes step back/forward for it, but who cares).

The benefits are enourmous. I can shoot my nikon D80 on auto iso at max 800 and with a really nice narrow DOF, I get just fantastic shots. Shooting at 1600 for me degrates the image quality far too much, 800 is way way superior.

Images are ever so slightly softer at 1.4 than 2.0, so I do find myself shooting on ap priority at F2.0, images are sharper and I still get great shutter speed. if Light is really how, I cut down to 1.4, but really, F2.0 is just great.

Images are sharp, good contrast and colour is very good too.
At 250 odd quid its very very cheap.

>>> Update to this review...
When I first wrote this review I stated that at 1.4 its softer than 2.0. Subsequently, I realised this isn't exactly true, its just that at f1.4, you get such a narrow depth of field, the camera does struggle to focus. Its not the cameras fault, if you set your camera to central zone focussing, even this small area can be over a wide depth of field, so no wonder the camer has a problem.

What I've found is, I do need to take a few shots to get eyes exactly in focus, so its not too much of a problem.

I don't use my 18-135 anymore - even in bright sunny days (when it's not raining ;-) I still get much better shots on this lens.

Great indoor low light portrait lens for Digital SLRs.......2007-01-08

I have a Canon 400D (and before that a Canon 300D) and use this lens as my primary low light indoor portrait lens for snaps of the family / events etc. The 30mm x 1.6 = 48mm (due to small sensor on digital SLR cameras) makes this an ideal standard lens. The optics are amazing with sharpness, colour tone and auto-focus speed are all highly impressive. Highly recommended.
