anselsmyhero: So at 7 mm the zoom lens has 114° angle of coverage, And the 8 mm has 180° angle of coverage. Can anybody explain to me why the angles of coverage and the focal lengths are not proportional?

The 8mm fisheye angle of view is 180 deg across the diagonal (corner to corner) The zoom angle of view is measured across the width.

Was is correct, Lightroom is singular, were is used with plurals. For instance
The cat was sitting.

HowaboutRAW: So no Samsung NX1, or Panasonic LX100, or Canon G7X--all kind of interesting cameras--and IR has already posted some raws from the Canon.

Also Leica uses DNG, so unless the newest Leicas only use a very very new version of DNG, older versions of ACR should work with say the S2(type 700), so this Leica V-Lus seems odd.

Greybalanced is correct. In the past Nikon, for instance, would not release proprietry information to Adobe. The Sillypix (sorry Silkypix - I will keep making that mistake...) situation is that they are Japanese and seem to be willing to work with Japanese camera manufacturers to make bespoke manufacturer specific versions of their software. The Fuji version of Silkypix will only open Fuji files, the Nikon version (NX-D) only work with Nikon files.

Be warned the prices quoted in the press release do not include the 25% VAT you will be charged.

Since when did 11000 Euro equal £11400. Last time I looked there were 1.2637 Euro to the pound. On that basis the UK price should be £8700.

digitall: A Sea of Steps, Frederick Henry Evans: one of my favourite photographs. Wish Australia was closer to England!

They charge a few pounds for a photography licence that, amongst other things, allows you to use a tripod and place its feet in the same spot as Evens used; like hundreds if not thousands have since he took the original. ;-)

qianp2k: Will be free or you need to pay for a prod version when it's officially released?

What you are reading is clearly stated to be the original press release for the beta version so no contradiction.

Interesting here in the UK WEX have V3 in stock - does not appear to be a shortage. It is the AW1 that is awaiting deliveries.

On Adobe CC Announcements: What you need to know article (182 comments in total)

Holw do these iPad applications differ from Photoshop Touch that I have on my Nexus 7? For instance changes I make on the Nexus are synced with my CC cloud storage and hence with my desktop. BTW the Lightroom Queen says existing photography plan users will retain their existing 20 gig CC storage and not be downgraded to 2gig.

On Leica T (Typ 701) First Impressions Review preview (2251 comments in total)
In reply to:

skeen: DPR were not able to do a test/comparison with the 23mm prime - I have the T, and the 23mm ... I've uploaded an OOC JPG and a DNG here: https://mega.co.nz/#F!Fh4giBAC!FEXKN1zGyA5RhYz2TcxjoQ

I don't know whether Leica said they did no corrections or not, but I think that for any manufacturer (not just Leica), the likelihood of them lying about this when it will be naturally discovered otherwise seems rather unlikely.

People are saying, "I just don't understand how they thought they could get away with this", well...the most reasonable explanation then, surely, is that there's just been some kind of miscommunication. That is surely the only thing that makes sense at this point...?

Downloaded the DNG and compared it in RawDigger (which applies no correction and ignores any correction instructions in metadata) and Lightroom. Very definite difference, Lightroom version is cropped significantly compared with RawDigger output indicating noticable distortion correction.

peevee1: So, Nikon and Panasonic have the same software now... SilkyPix.

I keep calling it Silly Pix for some reason.

Direct link | Posted on Feb 25, 2014 at 16:44 UTC

Anyone any idea which lens/camera combinations are covered by lens distortion tool? D700/16-35 f/4 is but 12-24mm f/4 on D1H isn't which is hardly surprising I suppose but the lens is supported on the D2Hs.

Antony John: Downloaded earlier this morning. Not quite as clumsy as CNX-2 and, as some have already pointed out, missing 'U Point' and some other bits and bobs that were in CNX-2 but the basics are still there.
Have also compared the straight 'from NEF' rendition vs Lightroom 4 and NX-D shows greater image acuity and superior colour rendition - as one should expect being 'OEM' software.
So, yes, there are negatives but Nikon are asking for input (a first?) and I think people should take up this offer and let's see what the final version will be like in September (the time the beta software expires).
I've been using Lightroom for a year now but re-looking at Nikon's offering I can see what I've been missing having (almost totally) discarded CNX-2 during this period.
Now if Nikon will offer a route to using Nik Software via the 'open with' (which currently doesn't work on NX-D - one is routed to the preferences screen) then I doubt that too many will be dismayed.

I have set it up so that I can do straight into Photoshop CC and assume you can do the same with Nik plug in .exe. You have to set this up in preferences. (Preferences is Windows only for some reason)
BTW Nikon have already issued second version of beta - 2 in one day. ๐Ÿ˜ˆ๐Ÿ˜ˆ

Article is a bit behind the times. My year old Nexus 7 updated to 4.4.2 a couple of days ago.

I don't see a 10 pin connector - has that disappeared? Also though you can use a traditional cable release can you use a Nikon (Contax) type cable release - believe it or not I still have one.

On Hands-on with the retro Nikon Df article (230 comments in total)

What on earth induced Nikon UK to only sell this camera with a kit lens? Surely the target market for the camera already have standard 50mm lenses in their armoury (I have two 50mm f/1.4 of different vintage and certainly don't want another 50mm).
I thought this camera might be a D700 replacement but.....

On Adobe releases subscription-only Photoshop CC article (397 comments in total)
In reply to:

Chris2J: I have recently bought Photoshop CS6 after much deliberation. I bought it on my budget account over 24 months, as the full price would dent my cashflow. Can I now somehow upgrade to Photoshop CC, or will Adobe let owners of CS6 have a free upgrade for at least 24 months to compensate? If not, this is highly unfair to recent purchasers who still need to get value out of their investment.

Does anybody know?

There is a reduced price rental for the first 12 months for owners of CS6 perpetual licence. See the Creative Cloud web site.
If you go down the CC route your CS6 can sit alongside the CC version, if you abandon CC in the future your CS6 will be still there and working.
By the way I always thought the one off purchase price of Photoshop far to high to contemplate but the CC single application rental deal has tempted me into installing Photoshop.
