Maybe you should mention that this app only works on a Nexus device since ie. Samsung hasn't implemented the API.

So my Galaxy S5 with the Lollipop update can't shoot RAW even though it's running Lollipop.

Come on Samsung!!

On Opinion: The myth of the upgrade path article (1304 comments in total)
In reply to:

TheEulerID: It's simply untrue that FF focal lengths aren't useful on APS-C. Firstly, the so called "classic" focal lengths are semi-arbitrary anyway. OK, a standard lens might approximate to a human field of view, but mostly it's a bit arbitrary. After all, who uses zooms only at what are recognised as "classic" prime focal lengths.

A 50mm lens still makes a decent portrait lens on an APS-C for instance. I you want a slight flatter perspective on the face, stand back a little and crop. (Perspective is defined only by camera/subject distance).

A 35mm prime provides for a useful WA on APS-C. A 70-200mm f2.8 works very well on an APS-C in my experience.

Yes, might want some special APS-C lenses (especially at the wide end), but only 2 of my 9 lenses are APS-C specific. Those APS-C lenses are still useful on FF when you want something more compact to carry as you can always work in crop mode.

+1 I started with KonicaMinolta and aps-c and ended with Sony FF. I am glad I had full frame lenses so I didn't have to buy any lenses when I bought the a900. We are some people who have to think about the costs too!!!

In reply to:

Tom Goodman: An opinion piece that could only appear on a site devoted to the myth that the camera makes the picture.

You could boil this down to one sentence: the best camera you have is the one that took the picture you wanted to take.

Completely true. I have made Great shots with my Samsung Galaxy smartphone.

On Ten things you need to know about the Sony Alpha 7 II article (270 comments in total)
In reply to:

Serious Sam: It wouldn’t be a Sony thread if people are not complaining about the lens line up.

In my opinion it is likely there is not enough finance resource to develop a new FF body and high quality optics hence they leave the job to Zeiss. Then there is the challenge of keeping the lens small. People already complain the size of the F4 70-200, imagine that lens at 2.8

One would argue that the others are doing it ok.

Lets start with Fuji, they have been making lens for 80 year so optics is not a problem for them, they just have to work out the sensor. Which is X-trans and its working out quite well for them.

Then there is M43. Well they have two and a half company work on this system. Panasonic, Olympus and the half is Leica. Therefore the system evolution is much easier. Just look at the two 2.8 zoom from Panasonic...remarkable engineering.

Actually the Sony a-mount 70-200 f/2.8 G SSM is not much bigger than the E-mount 70-200 f/4 G. The only real difference is the weight!

I think you need to review the Alpha 77 II before you make any photos with this camera!

On Canon PowerShot G7 X Review preview (435 comments in total)
In reply to:

Donnie G: I was convinced that I wasn't among the consumers that Canon's G7 X was made for because I have never been interested in owning any compact camera. Boy was I wrong. Although I have no interest in owning compact cameras, my teens are very interested in the category, and I am their "deep pockets". So I wound up buying 2 G7 X cameras, one for him and one for her. Between the 2 of them, they were able to setup the cameras without any input from "the broke old guy". After about 10 days, my gorgeous gal pal, Brandi, and I were able to decipher enough teen slang to learn that the camera features they worship the most are the programable click wheel around the lens collar, the articulated touch screen, and the ability to upload images to social media via Canon's Image Gateway service. I don't think that these kids are even aware of the other features, such as sensor size, lens speed, focal length, or even IQ. It takes better photos than their smartphones and their friends think its cool. :)

Why buy a product just because of the brand name. It only tells that one are driven by commercials and brand recognition rather than the quality and performance of a product.

As much as I think Sony makes great products I don't buy any of their products if I find them worse than a competing product from an other company.

In reply to:

tabloid: I think apple does a pro service…but you have to pay for it.

I use a A65 and as a full time professional photographer…Its more than ample for what I need.

There is no such thing as a "pro camera" .There is a simply camera that a professional photographer find adequate for the job.

I completely agree with you!. Also some Pros only have one body!! Lets see how the pro support will be in Europe. Hope it will be better!!

Greetings from a poor semi pro who only owns one FF body.

On Canon announces EOS C100 Mark II article (278 comments in total)
In reply to:

Bhima78: This looks good for professionals that are already shooting with lots of Canon glass... to the budding professional, this price point puts it squarely against the A7S with the 4K addon. Pretty sure the A7S with that addon will absolutely mop the floor with this though. Of course, maybe the A7S has more rolling shutter and this has none. Someone that is actually a videographer, chime in as to why you would buy this other than owning Canon glass already, over the alternatives (especially the A7S with the add-on).

Here in Denmark the national TV DR tv they use mostly Sony cams with fujinon or canon lenses.
Sony is a big player in the TV industry. Several movies are shot with Sony too....

To all the guys claiming they have a lens mounts that has wiggle. It's rotational wiggle you have. If it were axial it would ruin your photos because of a massive lightleak made by the axial play. The rotational wiggle is there also on a-mount and dosent mean a thing unless the tolerances are exceeded.

In reply to:

ChiTown1200: My A7 that was purchased right at the release time most certainly has a lot of wiggle in the mount with the 24-70 lens on it. I double checked all the fasteners on the camera and lens, nothing loose.
It doesn't seem to effect the excellent images this combo makes, but it is kind of annoying.
I very well might buy this product, just for piece of mind of fixing a problem that's not really a problem.

The wiggle you see are rotational and is there because of the tolerance on the lock nut. There is nothing wrong with that. But if you had any axial wiggle you would not be able to take photos without light leaking into the kamera and it would ruin your photos.

In reply to:

rwbaron: Appears to be a really poor design by Sony especially on a camera in this price range. What were they thinking?

It's not true that the lens mount can flex because of the plastic shim between the outer mount flange and the body. The plastic shim is so thin and the weight distribution so big that in no way the shim will flex. I am a Technical Designer so I hope I know what I talk about.

If it does flex it's less than 0.01mm.

Andy Dan: DXO test, that's what the reporter was refering to. I agree with Maeda regarding DR. Few people use a camera at ISO 100/200 only. Sony sensors have an advantage in the ISO 100-400 range. From ISO 400 to 3200 no one has a big advantage (better results for Sony at ISO 400 and better results for Canon at ISO 3200). From ISO 3200 Canon sensors have a big advantage. So overall sensors are evenly matched.

So, for landscape Sony sensors are the best right now. For various genres of photography at various ISO settings (architecture, travel, portraiture, macro, street) and low-light work Canon sensors are the best. Also Canon is better for sports and most professional sport shooters are using Canon because of the speed. Considering Canon outsells both Nikon and Sony it seems that even from an financial pov mr. Maeda is right.

You forget the ugly pattern noise of the canon and that the Sony have much better DR at low ISO and not much worse at high ISO. In a fact I think you can push the high ISO files from Sony more than a canon file.

I think most people usually shoots at 100-800 ISO or even 100-400. P.S. my 5 year old a900 has better shadow noise at low ISO than 5D MkIII when you push the shadows!

In reply to:

kevin_r: I'm just getting this definite impression that Amazon/Dpreview is at loggerheads with Sony.
They seem to be sending a message that Sony will be treated with scorn and contempt unless Sony ponies up some moolla somewhere.
Why do I say this?
Look at the treatment the Sony A77 mark II is getting even though it has been out on the market since August already.
Then, this specific article is clearly sending the message -
"Oh, sorry, we didn't see you there - your cubicle was so small and unnoticeable....!"

Great way to go, guys. Keep it up. Sony will soon cave in and spend some moolla as required.

Imaging-resource has just now posted a shooters report part 1 about the a77 MkII. But they don't have a review either. The writer of the shooters report found the A77 MkII to be a worthy upgrade of his guess what Canon 7D ;-)

IMHO I find the a77 MkII to be more exciting than the Canon 7D MkII but I bet we will see a 7D MkII review before we see an A77 MkII review. Isen't it right?

In reply to:

ozturert: Sony's head is so mixed that he cannot summarize their strategy in one sentence. Tell me about Alpha, NEX, E, EF, A cameras. How can I tell the difference between A77 and A7R, or will A mount be supported in the future, and if we see curved sensor in A cameras (ex-NEX) will we have to buy new lenses and adapters (as we had to when A7's came out), etc..
Sony needs to make-up their mind and stay consistent for 3 consecutive years to make their users fell comfortable. Right now Sony is all around the place and I cannot understand their long-term strategy.
"Trying to be the best" is not a strategy.

They are not all over. They are starting a new system with the FE mount which is identical to the E-mount, and then they have the A-mount. And adapters makes use of A-mount lenses on FE-mount possible.

In reply to:

Markol: So much better than the Nikon guy. Sony might not have the reputation yet but it seems they are doing a lot of things right in the imaging industry, contrary to some other areas like consumer electronics.
At any rate, it's good to have another serious contender in the game. Some other companies really have their heads in their behinds, like Nikon or Olympus.

Completely right. Sony are innovative and has a passion for photography!! And he was very honest too.

Direct link | Posted on Sep 24, 2014 at 13:46 UTC

This interview shows the lack of innovative spirit at Nikon. But maybe they have something up their sleeve. I interesting that say mirrorless has grown thanks to Sony.

You should review the Sony A77 MkII instead of a small boring news post about the 7D MkII. The A77 MkII is a close competitor to the 7D MkII and has an advanced AF system to. Actually it has more AF points than the 7D MkII. IQ wise i think the Sony wins because of a superior sensor.

But anyway it would be nice to compare those two cameras.

Hi Faisal.

Great to hear they solved the problem. I had 3 in about 2 months and they diden't manage to solve the overheating along with other issues while I had it. I now have the Galaxy S5 and it works great.

I shoot with Sony Alpha cameras A900 and A700 and have Sony Stereo and TV and they never let me down except for the a700 once.
