leica 28mm 1.4 is out and about on its own

No, it takes regular filters; I haven't figured out what the dummy filter is for. even looking at the accessories in the manual.
It sounds as if the lens shade works like the ones on the 21 and 24 Summiluxes, which screw in with an external thread that stops rotating just at the right point to make the edges of the shade line up horizontally or vertically. Those indicate the filter size on the outside: Series VIII for the 21 and Series VII for the 24. Does the new 28 indicate a filter series size on the outside of the lens?

What dummy filter are you referring to?

The dummy filter is a ring that you need to unscrew to expose the threads needed to fit a regular (49mm) filter. Outside it says E49.

Is the focus off because it has been sitting in a box, unused for a long time?

Any pics using it?

The same date (2014/08/11) appears on the labels of three copies of this lens which just arrived in California. So now we know when the boxes were printed.

jrp - There are two components. One is a hood. It screws to outer threads. The other is a simple ring. When not using the hood you screw the ring to the outer threads to protect the thin fragile outer threads. That ring is JUST to protect the threads when not using the hood.

A filter will screw into the the 28lux as any normal filter would screw into any lens.

It takes 49mm filters BTW. Some might not fit with the ring and hood. I'm sure though that the B+W MRC x-pro nano slim ones would. And so would the Leica ones.

BTW, you put the filter on, then put the hood on.
Or if you're using the thread protector ring.. You put the ring on, then you put the filter on.

Adam, this might be a new thing. They have a metal ring protecting the inner thread instead. Here is a couple of pictures from HK dealers.

There's no ring protecting the outer threads?
I just had a conversation with my friend yesterday about his new 28lux. He was telling me the same thing, but I thought he meant the outer ring. So I was explaining to him the same way I was explaining to JRP. WHOOPS, hope I didn't confuse him :D

He was trying to tell me he didn't know how the filter fit on.. I guess I need to call him up and tell him there's a way to unscrew the inside ring.. LOL :D

I like it - I've had one on and off since 2013 - here are some very short thoughts and a few snaps

Jono, thank you for sharing your hands-on experience and images, especially for DNGs.
I like 28/1.4 Lux performance a lot, bokeh at f/1.4 particularly! It seems to have the lowest distortion among 75° FOV lenses which is a significant advantage for me when shooting portraits.
What I'm also interested in is how well it's corrected for comatic aberration. An image of a scene with lots of light points shot wide open would be helpful in determining that.

Here's a sample shot with Distagon 28/2 ZE wide open:

I hope 28/1.4 Lux performs way better than 28/2 ZE in regards to coma.

Also, looking forward to comments in regards to field curvature.
I see a severe field curvature at f6.8 in the image of the tree (http://www.slack.co.uk/2015/summilux28/index.html#/view/ID255558) when examining the DNG file (MM044108.DNG). Crops in the left corner are way sharper than the grass on the right.

Folks who now have one of these, is the lens correctly recognized by the firmware? M240 firmware was last updated in November 2014, at which point the lens existed but was not released for sale. There is no mention of this lens in the "what the new firmware does for you" readme note, so I don't know what to expect. Maybe new firmware.

Re: leica 28mm 1.4 manufacturing dates

It looks like the select August 2014 batch has now been sold out. My own copy is on its way to me and is dated February 2015.
