On Canon PowerShot G1 X Mark II Review preview (328 comments in total)

Well, it looks to me Canon is still kinda lost...! When you see the mirrorless cameras by Sony, Olympus, Fuji,... For example, the Sony RX100 II has been around for a while now and Canon shows nothing new over it. Quite sad.

On Pentax K-3 Review preview (443 comments in total)

Seems a great camera, at a good price! I thought the K-3 had a FF sensor, though. My bad!

On Sony Cyber-shot DSC-RX10 Review preview (423 comments in total)
In reply to:

Just another Canon shooter: "... with its 24-200mm F2.8 lens". No, it has an 8.8-73.3mm, f/2.8 lens, as it can be seen from the picture. If you want to convert the FL into 35mm equivalent (but not the f-stop?), this should be made clear. The casual visitor to this site would be very confused.

IMHO, for all practical aspects the RX10 has a 24-200mm f2.8 "equivalent" lens! ( Actually, that's the same equivalent f.l. the good old Minolta Dimage A1 had on a 2/3" sensor - I still have one in excellent condition ).
Anything else is academic in the most.

Fredy Ross: Surprised no mention of how heavy it is

IMHO it's not heavy considering all its features and the fantastic lens! Besides, you may cover most general photo needs without having to carry any accessory ( maybe just an extra battery )!

On Samsung NX mini First Impressions Review preview (524 comments in total)

The Nikon 1 as launched was ridiculous, it took Sony's RX100/100II/10 to make the 1" sensor show its value, when made right and put in great worthy bodies. It's good to see Nikon has reacted well and is getting it's act together now, in spite of a still ridiculous price. I hope this Samsung is just the first iteration of others to come, it shows a very nicely simple concept.

On Olympus OM-D E-M10 Review preview (270 comments in total)

I still don't get it, the Oly OM-D E-M10 seems pretty nice, but how can it get a "gold" and the Sony A7 FF a "silver"? IQ, AF, ergonomics, technology, don't matter any more, only a retro look and lower price? Whatever... DPR is really not to be considered serious on their conclusions/ratings any more!

You should also check the Sony RX10 ( regardless it has a 1" sensor only..! )

On Nikon 1 V3: a quick summary article (581 comments in total)

I'm starting to like this camera a bit more, but IMO it should've also kept the model with on-camera EVF. Anyway, Nikon has to do a big cut on its price for it to be considered instead of a Sony A6000 or even an RX10.

On Nikon 1 V3: a quick summary article (581 comments in total)
In reply to:

pwilly: Comparing Apples to Apples, the tiny sensor comments are just uninformed. A tiny sensor like a 1/3.6” has a 5mm diagonal. 35mm has a 43.3 diagonal, APS-C is 30mm 4/3 is 22.5mm and 1’ is 16mm. Micro 4/3 folks frequently claim that there is little advantage to FF vs. 4/3 in most photos and that is true. Unless you are looking for extreme low light, or very narrow DOF an equivalent photo can be taken with 4/3. So with just about half the diagonal 4/3 is sufficient.
The Nikon 1 sensor has 71% of the diagonal of 4/3. Once again if we are talking equivalent photos the Nikon 1 sensor can take the same photo, but then add the stunning AF tracking and for action there is nothing like it.

One great advantage of an FF sensor over any other smaller size is to allow deep cropping without losing image detail ( provided enough pixels are available ). That means you don't really have to have big/heavy lenses ( typical for FF ) to shoot smaller and/or farther away subjects. That was my main reason to totally move to FF. Of course, the shallow DOF and cleaner Hi ISO are also major.

In reply to:

Lucas_: IMHO it's outrageous to give a Gold Award and an 87% note to this camera and Silver with 80% to the fantastically innovative Sony A7 ( not to mention the A7R, which is clearly at another level and got Gold / 82%! ). It's about time DPR realizes that their reviews "conclusions" have actually become a joke! I can appreciate the level of camera features/controls details and specs they cover ( which IMO is the good value of the review ), but I've learned to just don't care at all about their final conclusions ( sometimes hilarious ) and rating!

I take it that all of you have already spent some time with the A7, right? If not, I'd advise you to do that and while you're at it, also try a 7R! Don't just rely on reviews and "nay sayers"..! As for lenses, that's a non-issue, you can also use most lenses you like from Nikon, Canon, Pentax, Leica, Contax, Voigtlander, etc, even Minolta and Sony...!

On Sigma to pay Nikon $14.5 million for VR patent infringement news story (200 comments in total)
In reply to:

expressivecanvas: If Sigma dropped all Nikon mount lenses over this nonsense by Nikon, who would be hurt the most? It would not be Sigma...

Sigma should put more effort into m4/3, Pentax, Fuji X and maybe one or two others. Significant numbers of annoyed Nikon users would be annoyed that Nikon forced Sigma to drop development of their mount and probably drop their Nikon gear for greener pastures with more options available.

In the end, Sigma could garner more sales... along with more users of m4/3, Pentax, Fuji X...

If Nikon wants to stand alone and push away all third party development, let them play with themselves...

I believe Nikon is isolating themselves which just may be corporate suicide in such a small world.

I'm sure Sigma will continue building lenses with the Nikon mount, they'd be crazy if they lost that market! Anyway, I hope now they will be giving a bit more attention to others, especially Sony, who have excellent lenses but at very high prices. Sony is relentlessly investing in its imaging division ( in spite of their Corp. financial troubles ) and slowly becoming a sizeable threat to Canon and Nikon.

Langusta: Good job Nikon! Finally you found something where you can be successful...

I believe the Nikon DXOMark champ is the D800, which uses a Sony sensor.

The Pentax K-3 also has a Sony sensor.

On Panasonic Lumix DMC-GH4: a quick summary article (456 comments in total)
In reply to:

ClearVid: The GH4 does not maintain the bit-rate to resolution ratio quality at 4k resolutions that it does at 1080p resolutions. That is a disappointment and means it is not going to be until the GH5 that we get full quality 4k. SD cards can't handle the bit-rate needed for 4k full quality right now and without HEVC the data size is quite large. If the GH5 uses HEVC-IPB and HEVC-ALL-I then that might help. UHS-3 and UHS-6 SD cards should also help.

Was a GH5 already announced?

Scottelly: I think I'll still get a Sony A77 first, but this thing looks amazing! I want one of these now too. Until this thing, I really wasn't interested in m4/3 cameras.

I'd wait a bit more for the A77 successor ( to be launched sometime this May ). I wonder what features Sony will have in it, since currently the A77 is quite well loaded already, but why not 4k video...?
