Just ordered 19mm and 30mm from digital rev for $378 total (with free shipping). The lenses (especially 30mm) got some great reviews. This is will breath some life into my 5n which I stopped using for a while due to lack of reasonable priced quality primes. Getting two nice prime lenses for this price is awesome, 2.8 minimum aperture doesn't really bother me, 5n has great high iso plus being a mirrorless I can get away with slightly lower shutter speeds.

Please post back later with how you like the 19mm! I wasn't considering one because it's a focal length I've never really grown to love, but I do admit it would be a nice pairing with the 30mm.

I agree with you about the f/2.8 minimum aperture not being a bother, especially as it seems the 30mm performs quite well wide open.

So far so good with the 30. The first two I've processed:

Nice shots.

How do you like the handling. Given my earlier comments, should Is end mine back as defective?

Focus may be marginally slower than the kit zoom. I haven't noticed any aperture wackiness - as a matter of fact, I've never seen the aperture open and close like you describe with either the 30 or my kit lens. The NEX views at the taking aperture, not in stop down mode - unless you have something enabled in your camera's setup that I don't?

The closest I can come to what you describe is in P or S mode by waving the camera around with the shutter half depressed so the aperture constantly changes. It does make noise when I do this, but it isn't objectionable.

Thank you. I shall persevere, as I like the focal length and the lens itself is very good.

I'm not 100% sure, but there is an option that might affect this...

MENU -> [Setup] -[Live View Display]

Setting Effect ON (Default) will show live changes to exposure, WB, etc on the display.

Setting Effect OFF might operate the camera in stop-down mode, if I read the manual correctly.

Check to see what you have set, and try the other option to see if it helps.

I have just received the 30mm. It's nice and seems to take sharp pictures wide open.

But do others hear the same rattling noise in the lens when the camera's off and rocked back and forth?

I don't have the lens (yet?) but I've seen this described so many times it seems to be a feature, not a bug.

It's mentioned in the manual. Nothing to worry about.

It depends on the light that you're in. If the light is low, the lens will briefly open up when you AF and then quickly close before taking the picture.

I'll have to try that! It would make sense, though - it might be a response from the camera to ensure enough light on the sensor for accurate focusing. If that's the case I would expect the same with the kit lens, and more frequently.

Just got my 30mm and 19mm in the mail today. Didn't get a chance to take any "proper" photos but first impressions are all positive. The lenses are so nicely built, small and light and seem to suit my nex 5n perfectly. I reckon 30mm will be on most of the time, and 19mm is small and light and will fit in jacket pocket easily.
However, I wont be selling my 18-55 kit lens or 16mm as they can do some things sigma's can't.

This lens is amazing!!

The AF is fast and spot-on (if the right AF-setting is chosen in the NEX-7).
The image quality is astonishing (esp. for a lens at the price!)
It looks great in black on the NEX-7.
Even with the "diva"-sensor of the NEX-7 is works together extremely well.

The Sigma EX 2.8/30 EN is a definite recommendation for every NEX user!!

Still very happy with the Sigma 30/2.8...

Welcome.


No attachments showing. Some shots from the 19mm would be interesting.

I got the images to embed now and have included a couple from the 19mm, nothing to great but I've only had them for a week and now I'm busy at work with overtime for a few weeks so my schedule is limited.

I made a few comparisons of the two lenses side by side, I'll post one and if you would like to see a few more I will include them other wise I don't want to spam the post. These are straight jpeg files out of the camera, nex 5n. I usually shoot raw if its something I want to keep but for general purpose jpeg is fine.

Hi, just got my copy this week...iīm happy with it!

I wished it was smaller butīs almost ok...itīs very sharp and the focal length allows me to play with dof.

When set on manual focus the ring must be moved very gently if not the mechanism jams, i guess the ring is too thin...

Itīs slower than my sony 16mm lens to achieve focus, but itīs ok since the focal length is larger...

Iīm pretty happy with this alternative since itīs not expensive and grants me a great service being 45mm fov...the 30 mm length iquite "normal" and donīt show the wides erspective distortions...

Bye

has any one got a link to a good impartial comparison between either of these lenses and the 18-55 zoom?

elmer, I've seen a few comments about the focus ring but I can't get mine to bind unless I grab it like I'm choking it hard. How are you trying to use yours?

So, does the 30mm and Nex7 combo offer blazing fast AF?

I'd say good AF for a CDAF system, but not great. I'm surprised how relatively good manual focusing is with the Sigma. Despite being focus by wire, it is pretty responsive. Not M lens good, but certainly better than Contax G with adapter.

Not blazing fast IMO, but plenty fast enough for my uses.
