The Nokia is still surprisingly good and for posting online purposes more than sufficient. If you only carry a mobile phone then using the Nokia is much better than having no point and shoot with you. That the quality of a mobile is coming even close to the S120 is no small feet and is impressive nonetheless.

If you consider that most people take most pictures in the focal range of 24 ... 50 mm focal length, where the Nokia even exhibits an edge this becomes even more darn amazing! If I would own both devices, I/d probably sell the S120 :-)

Thanks to the connect team for this comparison!

On Pentax K-3 real-world samples gallery news story (150 comments in total)

Interesting pictures with appropriate post processing in different lightning, different focus / bokeh and different types of composition will be much more informative. Barney Britton wrote today that dpreview staff should live with a camera for a month and shoot with it every day in real life. I admire the goal, I can not see it executed here.

On a 16 MP APSC you also need better lenses than the ones used to judge of what the sensor is capable off. Shooting RAW and processing in Lightroom would also be advised. Most people who spends this much money on a Camera will not use the images unprocessed. Besides that I found the images uninspiring. Executed such as this with no commitment to the effort I would be fine there is no sample gallery, as I can not find information in this one.

Better lenses:
FA 35 mm F/2 AL. Superb @ f/2.8 ... f/5.6
DA 77 mm F/2.4. Superb @ f/2.8 ... f/5.6
These lenses are relatively low cost and optically good enough to really use this sensor.

On Tamron to develop 150-600mm F5-6.3 ultra-telephoto zoom news story (193 comments in total)

I have a Tamron SP 300 mm f/2.8. It is bitingly sharp wide open and remains very sharp with the x2 tele converter. That lens best the 80-200 f/2.8 L from Canon of my friend. So Tamron has shown they know how to do it and chances are this lens will be very sharp. Can't wait to see a detailed review. For me this would be ideal for dragon boat races, he he.

In reply to:

maxola67: So, if it's optically better than my 16-50 the latter would be sold.
I'm rather annoyed by the vignette produced when using pop-up flash(some pics went to the trash because of that).

If it works for maxola67, why make it sour for him? Different people photograph in different ways. Some features are important to some, others are not. This lens is significantly smaller, it will vignette less with the pop up flash on the wide end. If this is what he needs to make his pictures work, then switching to this lens is the right choice for him. It sure looks like it is not the right choice for nicolaiecostel. My point: Please do not impose your way of photographing onto other people!

For everybody complaining the price:

take one picture with both lenses side by side:
a) This Pentax (dwarf)
b) Sigma 18-35 mm f/1.8 (behemoth)

Sigma went for the amazingly fast aperture of f/1.8
Pentax went for the amazingly small size

Both lenses are amazing in their engineering accomplishment and both ask an equivalent price for it

(The sigma lens already has proven it's IQ, the Pentax one still has to deliver)

This could be a perfectly balanced lens:

* Great IQ
* Great Handling and Materials
* Small and light weight
* Quiet AF for Video
* Unobtrusive for street
* Potentially good bokeh (rounded blades + good lens formula)
* weather sealing
* Fast AF with Quickshift (manual focus override)

So lets wait for the test results. If they are excellent, than 1000 USD is a price many will be willing to pay for it, including me.

A truly unique and useful lens. Perfectly balanced to be the outstanding feature.

Ah, if the next Pentax Camera is like an A7 from Sony, except have the viewfinder in the corner, then we have a really cool system! (And I do not care for the thin camera body if each lens has to be longer to compensate for the short flange mount, but I care the build in EVF and I care it is placed in the corner like Range finder cameras, as in the corner it is more convenient to use and the camera does not collide with my nose)

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

Very romantic retro design.

Using excellent Nikkor manual focus lenses on such a great sensor with no any focus help (no split screen on the OVF, no live view in the viewfinder with magnification) will soon cause a very frustrating awakening.

The only way to focus will be at arms length same style like with a point and shoot using Live view and magnification.

All my Pentax DSLR can change the split-screen (and I use them successfully). I am surprised this camera can't. On my Pentax it is a cute option. On this camera which is emphasizing the use of manual focus lenses it would be a must.

HubertChen: Sony 7 Cameras: Small, powerful and reasonably priced
Sony FE Lenses: Big, slow, expensive

I always use both: Camera + Lens. What is the point of a small camera with big lens? Seems Olympus, Fuji and Pentax have bigger camera bodies. But once lenses mounted to them, they have smaller and lower cost systems with faster lenses.

I am really impressed with the alpha 7 cameras. I applaud Sony. I worry the big, expensive and slow FE lenses will hamper the success.

Dear Rooru S,

If it is a fact that shorter lens mount must produce longer lenses, than I prefer the longer lens mount. I have 5 lenses in my bag and 1 camera. 1 x longer + 5x shorter is less volume and weight than 1 x shorter and 5 x longer!

This aside I do not believe this is an obstacle which can not be overcome. Sony has shown it with the full frame compact camera. Short flange and still diminutive lens.

Also Leica lenses with Lens adapter still seems smaller than what Sony was showing.

Pentax full frame lenses proof that this can be done! And why nobody here cares? What is so exciting about a tiny camera body, if it is almost irrelevant compared to the lens sizes? Or even worse, such a tiny body is not fun to shoot with large lenses. I shot the NEX5 with a 70-200 mm f/2.8 and after only half hour I had a cramp in my right hand. I never had before using a DSLR with the same lens shooting a whole day! I just think tiny camera coupled with big lens makes for bad ergonomics! What am I missing?

@orfeas76

Yes, you can! I shot Sony NEX5 with an adapter and Pentax lenses. Exposure coupling was very usable. AF of course not. Up to 100 mm focal length using manual focus with the magnification in the viewfinder makes for great focus experience. Starting with 200 mm you can not handhold the camera anymore when using magnification for focus assist. Leica does not really make long (M) lenses, so this should be no problem for you. I found focus peaking at f/2.8 paired with medium tele excellent glass is not accurate enough. That's why I used magnification to manual focus.

Good quality lens adapters are available from metabones and novoflex. You want a good quality one in this case using this high resolution and this good lenses, because tiny manufacturing tolerances will show in your image. Michael Reichmann prefers the Sony 7R over the Leica M240 when using Leica glass. I think that says it all: http://www.luminous-landscape.com/reviews/cameras/sony_a7r_hands_on.shtml

The FE lens mount is brilliant, and compliments to Sony.

Sony has 3 lens mounts now: Alpha, E and FE. And this camera can use them all. With all automatic couplings. Great backwards compatibility and yet most modern features in one lens mount. Sony needs to be applauded to allow Sony users to reuse their lenses instead of forcing them to re-buy in a different mount. Very commendable.

As for the future it will be very interesting to see how this plays out. Will Sony over time consolidate the lenses to the FE / E mount? E for APSC and FE for FF? And you can mix and match to your hearts content. Use FF lens on APSC Sensor and APSC lens on FF sensor? And whenever you come across legacy alpha glass, you use an adapter.

I am curious to see if this is the end of the DSLR for Sony? Personally, I already do not miss the OVF any more :-)

Sony forgot photographer have noses.

This camera has an EVF. Why is it placed in the middle of the camera, where I need to twist my neck and squeeze my nose against the display? Not convenient and will always leave smear on the LCD. If you have a Mirror Box, your OVF has to be here. An EVF is connected with flex PCB. You can place the EVF where you want to. And I want the EVF in a conveient position. Not in an inconvenient one.

Look at cameras from Leica, Zeiss, Voigtlander and Fuji and the viewfinder is in the corner. Very convenient to hold to the eye. No Neck twisting. No nose squeezing. No Display cleaning.

I presume the design is made by the same team that created the NEX menu system? It is a shame to have so great technical prowess and then not utilize the best possible design.

These kind of usability flaw more influence buying decision for pro photographer then IQ. All cameras today have great IQ. But do they lend themselves to great shooting flow?

Dear tanmancs,

Sony is offering the camera now for purchase. The cameras have fantastic specs. But the lenses are simply the opposite today: Big size, slow speed, 200% overpriced compared to similar options. This simply need to be considered by anyone thinking about buying these amazing cameras. Why is this so hard to understand: Cameras do not take pictures. Camera + lenses do. It makes no sense to consider the camera alone. You must consider it with lenses. And if I buy a camera today, I must buy the lenses available today. And today this system is not convincing at all, due to the lenses.

@ harold1968
The 35mm is also only f/2.8. If f/2.8 is extremely sharp @ 2.8 it is maybe an OK deal. However, I have a 35mm f/2, which I shoot half of the time at f/2 and the other at f2.8 and f/4. You could say that f/2.8 on FF is as good as f/2 on APSC. However, I paid for my 35mm f/2 400 USD, and it is an extremely sharp lens. That Sony lens of same focal distance is a stop slower and double price. So I hope you forgive me if I am not impressed. Please always see my comments in the context, that the Sony alpha 7r is so wow so it is a double stark contrast that the lenses are so meh.

@ Rooru S
You say longer lens mount makes smaller lenses and shorter lens mount makes longer one? Well in this case I take the longer lens mount and smaller lenses. I usually carry 5 lenses with me and one camera :-)

Viewing from Canon EF or Sony alpha: Yes, the new lenses are smaller!

Viewing from Pentax full frame lenses: The new lenses are still bigger than faster glass full frame from Pentax

If you compare it with lens sizes from Sony, Zeiss, Nikon, Sigma, Canon, then you are correct, nothing special about the size of the new EF.

My point was not to compare with what is. My point was to compare with what could be!

Sony really impresses by shrinking the camera. I just find it sad, that they forgot to put the same zeal to the lenses and shrink them too! It can be done:

I shoot sometimes with a Canon 5D and with a Pentax K30. I use similar lenses on both system. In general the Pentax lenses are diminutive to the Canon lenses. The IQ is about the same. The Pentax lenses I have are full frame, they are not APS-C lenses. I am certain, as I also shoot them with my Pentax LX, which is 35mm film. My lenses do have AF, of course only when used on the digital body.

(to use the link you have to remove the space in the domain name)

There are some in the Pentax community waiting for a Full Frame camera for their Full Frame Pentax glass. This Sony with an Adapter fits the bill.

And maybe it works also the other way around. If you want this camera and want small full frame lenses then get an adapter and you can use: Leica M, Pentax K, Voigtlander, or any other Full Frame lens you like (or own). Thanks to Intelligent Auto ISO you will have even good functioning automatic exposure. With the 3 lens mounts listed you can have an mechanical Aperture Ring. I used Sony NEX 5 with Pentax K lenses and usability was fine in terms of lens coupling.

Michael Reichmann looks forward to use the alpha 7R with his Leica M Lenses:
