I love my 50mmƒ1.4G

With no images, you should be spanked :razz:

Love your Flickr stuff, very sharp lens that! It's on my shopping list but may have to be transferred onto my Christmas list as i need to cover 17-40mm at some point. I'm not sure a 50mm prime will be enough for the wider stuff. Great lens though, BEST I HAVE SEEN! and that's from all examples of images and the 85mm 1.8 is a damn close 2nd. They are up there with the 'L' glass in my opinion.
 
Yes, you can't compare an ultra wide angle lens designed for digital cameras (no crop) with a standard prime lens. The effective focal length of the 35mm on a Nikon will be 52mm.
 
Yup, the good ole' fiddy
 
I'd love one of these but I have to make do with a mere 1.8 on my 50. I have a 30 1.4 to make up for it, absolutely love it and I only got it today! I've come a long way from the 'I won't need any other lens other than what comes with the kit' days of two months ago, this 'hobby' has cost me an absolute fortune already!

The 1.5x crop affects the 10-20mm as well. Both are designed for DX bodies.

not sure what you're trying to say here, Radiohead is right and you appear to be agreeing with him but saying you don't agree?

DC on Sigma means the same as DX in Nikon speak.

I don't think we agree :) DX is not the same as DC. DX works on film and digital (although cropped). DC only works on digital and is NOT cropped. At least that's my understanding and experience of the Sigma 10-20mm DC.
 
DX is the same as DC - it refers to the image circle projected by the lens onto the sensor and matches the smaller size crop sensors found in most DSLRs

from sigma for DC

DC (DC Lens)
These are special lenses designed so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus ! including compact and lightweight construction.

From Wiki for Nikon DX

The Nikon DX format is an image sensor format of approximately 24×16 mm. Its dimensions are about 2/3 those of the 35mm film format (29mm vs 43mm diagonal, approx.). The format was created by Nikon for its digital SLR cameras, many of which are equipped with DX-sized sensors. DX format is very similar in size to sensors referred to by other camera manufacturers (Canon, Pentax, and Sony) as APS-C, so the terms are sometimes used interchangeably.

Both will work on 35mm film - but both will cause vignetting. The image circle will be recorded if its projected onto film or sensor, but more modern lenses will be optimised for a digital sensor

Cheers

You are absolutely right. I just double-checked my EXIF. I was so convinced that the DC line was specifically to eliminated cropping! Sorry.
