Kamox: Sure not the same thing, but 1/5 of the price:
if you attach this (Leica-expensive) TS lens (which has a usable area of 36x44mm) to a Canon 5DS R, you'll end up with 92 MP.

justmeMN: I suspect that the future of still photography is pulling still images out of short high resolution videos. It certainly would help in capturing a "decisive moment".

Spray & Pray with pre shutter capture in 2001 on Olympus E-100RS

Wonder how successful it was.
Sorry a bit off topic

Wonder if there is any chance of the "ancient" A7R picking this up? (missed out on shutter shock upgrade due to mechanical limitations )

Sports Shooter: all sounds great but why 72mm filter thread? why not standardize with 77mm ( 16-35, 24-105, 70-200)?

Yep, but can you still use the lens hood?

Mike Gerstner: Canon DPP........

It would be interesting to see a couple of the images processed in DPP to see if the native software deals with the shadow lifting any differently/better(?) than ACR........or supply the raws to allow a couple of the users to have a go at it.

Thanks, MIke

Agree. I think DPP should always include some images processed using the camera maker's software in addition to OOC JPEGS.

Thanks for posting this interesting article.
Would be very interesting to see a blog on how you actually get in and adjust a lens.

In reply to:

siggo: Am I the only one who thinks that a LENS test should test the LENS and it's optical properties? Then we can choose LENSES . These tests include the CAMERA as well. Sony offer adaptors for other lenses. How can we choose those lenses when their sharpness was determined on a different (possibly inferior) sensor. Sony will be delighted that their lenses appear fantastic here, in part due to their 36Mpix sensor.
Obviously as a Lens/camera combination checking sharpness etc these tests have an important role, but perhaps Sony has opened up the need for camera independent lens tests to be included on sites like this. Apologies for long post and maybe it belongs in forum section

Can't see edit button now.My comment may be wrong, need to check how MTF 50 is found. Apologies. However reviewer himself said good result partly due to sensor.

OBI656: Because of this update I purchased A7R and what a pleasant surprise ... If Zeiss optics will proof their reputation I will damp my CANON system.

Obviously your store is not in Hungary or you would be needing to get permission from the strangers....tears or no tears!!! 8-)

jhsymington: An update of my post two hours ago - I ran the update again on the A7R and it worked second time round. Ignore the fixed red light but otherwise dead camera and just try again - the update will start halfway through but the second time it concluded successfully. Not a great process Sony!

From posts on other forums there are a lot of users "making errors" some needing 5 or more tries...

Direct link | Posted on Mar 20, 2014 at 07:19 UTC

Barney, as so many are hopeful the "image improvements" will address some of the issues you highlighted in your review, does dpreview plan to check? eg selective noise reduction overshoot, does it now avoid worst shutter speeds for shake in auto ISO? , jpeg NR etc.

On article Nikon 1 V3: a quick summary (596 comments in total)
In reply to:

olyflyer: What a stupid idea those Nikon geniuses came up with...

Optional EVF, you have to chose to use a flash or an EVF... the same stupid idea Olympus implemented in their entry level mirrorless cameras. While the flip LCD is nice and useful, the removal of EVF is the craziest thing Nikon could do with this system. No future for me there, glad that I bought the V1 which is probably my last Nikon 1, unless Nikon makes one WITH an integrated EVF.

Yep, as the great philosopher Stephen Wright said "you can't have everything: Where would you put it?" Wanting a usaeable viewfinder in bright light and fill in flash is hardly wanting it all though, it's a given for anyone but the camera phone brigade IMHO.

In reply to:

Jogger: Seems ok for budget video folks.. but, why would anyone buy this for stills when the A7 is cheaper, much smaller, better built, and with 4x the sensor size... at this size and price, you might as well go for the D610.

???
This site gave brilliant results for 35 and 55 Sony A7R lenses.
Limited range yes, but 55 one of the sharpest they have tested.
