On Leica T (Typ 701) First Impressions Review preview (2291 comments in total)

At this price point the EVF really should have been included. This is about haptic. Leica shooters would want a viewfinder. An external one makes this camera very cumbersome in handling. And good handling is one of the things Leica users pay a premium for.

Juraj Lacko: That brushed aluminium will pick scratches like crazy.

There are different Aluminum alloys, some softer, some harder. And then there is Anodizing, which creates a very hard surface. So if you combine a hard aluminum alloy with a thick layer of anodizing, it can be very scratch resistant.

On A travel-sized large-format 4x5 camera? article (219 comments in total)

Buy a Zeiss Ikonta used with 6x9 cm roll film. With a Zeiss lens, precise focal distance markings and a better balance of film format to hand holding, you will get sharper pictures at faster shooting speed (Roll Film) and still higher resolution images. The Zeiss Ikonta is fold-able and I used that to have lens movement. Not too precise, but much better than no lens movement. Great to increase depth of field in landscape photography and with practice works well enough.

This camera will certainly qualify to shoot with a unique device and film cost will not kill you.

As for scanner, use your 16 MP DSLR with a Macro lens. Works fast with excellent quality.

For anybody looking for a different photography experience, this would be a more practical one.

When shooting black and white, you can benefit from larger latitude than your DSLR, so at least there is a technical benefit to go through this pain.

Unfolding this camera on party will also make it easy to start a conversation :-)

Wow, amazing lens! Sharp wide open, nice bokeh, no purple fringing. And really very nice rendering. I am sold.

Except it is almost 1 kg and the size of tele. But then again no other 50 mm f/1.4 at this quality level is any smaller. Congratulations to sigma.

And thanks to who took the sample shots. Very useful for evaluating this lens! I would have cared for some landscape shots @ f/5.6 with a 36 MP sensor. I would hope it to be extremely sharp, but then it would be nice to see it.

I am very surprised for such an amazing lens only so few comments.

At this size and price and battery capacity the most straight forward way to reduce noise is simply to cool down sensor and electronics with a peltier element. Works wonders for your Signal to Noise ratio and is very easy to do. It is simply not done in consumer cameras due to size and battery usage.

Many DP Merrill users have 2 or three of these cameras, as each lens comes with a camera. For such a use case it is surprising to design a camera that protrudes in the rear and in the front, making the carry bag for several DP Merrill cameras that much bigger.

On Fujifilm X-T1 First Impressions Review preview (1656 comments in total)
In reply to:

Low Budget Dave: I hope DPR will do a complete review of this soon. If the tracking AF really is good enough for sports, then Fuji nailed this one.

I am a huge fan of Fuji. Yet how is this better than the Olympus? I has great AF, great glass, great EVF, great button layout, great customization. So up till now it is a par. But Oly also has in body image stabilization. I'll give Fuji the aperture ring, which I really miss on my current camera :-) And believe it or not, having an aperture ring makes teaching photography much easier. I always go back to my film cameras to explain aperture and shutter speed to newbies.

HubertChen: Fuji keeps impressing me by making a practical innovation of something that has not been improved by all other companies for decades. This new layout makes lots of sense. In Video compression regularly more information is given to luminescence than color information with great success.

That is simpler indeed. Fuji just went two extra steps:
a) making green and luminescence bigger as we are more sensitive to these.
b) randomizing the layout to reduce moire.

On Using third-party lenses on Sony Cyber-shot a7 / a7R article (495 comments in total)
In reply to:

HubertChen: Thank you for this great Article. I was contemplating to buy the Sony a7. I am currently using a Pentax DSLR and got very used to shoot exclusively with manual focus lenses in Live-view. Pentax has no EVF option. So I am using a very big LCD viewfinder. The EVF of the Sony is very renowned and considering that the Sony is Fullframe and all my lenses are full frame I was very tempted. Until I read your Article that is.

There are a couple of things I love about my K30 that apparently the Sony does not have:
1) With one button press I can engage magnification for manual focusing
2) I can dynamically adjust magnification in an instance with the rear wheel
3) Shake reduction works exceptionally well. I frequently shoot with my 50mm lens in 1/15s and get razor sharp results
4) Almost no jelloing in magnification view up to 200mm.

A pity the Pentax has no short flange mount. You would be very happy with the User Interface. Buttons are where you want them.

@ Plastek: Thank you. My point was not pro Pentax K-30. My point was for not moving away from it towards the A7, meaning I was surprised that this excellent camera of 2000 USD did not had essential features my 400 USD camera had. I am aware that many cameras have excellent UI, with the current Olympus possibly to have the best. The A7 was tempting over the Olympus for being full frame. The poor usability as pointed out in the Article made me drop this idea.

On Pictures emerge showing widely-leaked Fujfilm 'X-T1' article (373 comments in total)

What am I missing? The X-T1 has the viewfinder in middle of the camera, which is ergonomically bad, as now my nose is colliding with the display. The previous X-Models have the viewfinder in the corner of he camera, which is way better.

Other then than the bad placement of the EVF, what is the difference?

And do not get me wrong. I love the Fuji X-Cameras. They are very well designed and work like a charm. Just do not see the excitement of bad placement of the EVF and why to create a new camera family? If they want to increase sales, work on cost down of the wonderful X-Gestalt.

In reply to:

tornwald: So far none are able to come close to the Foveon design Sigma has.
I am not sure they ever will because they want the best of both worlds.
Foveon is uncompromising, it has its weak points, but when used right, the output is unmatched by anything out there.

Since my new camera has great Image quality at high ISO I regularly shoot at 1600 ISO. To me and my colleagues higher IQ at high ISO is more important than increasing the resolution. My camera has 16MP and most images I publish are for the internet and published below 1MP. I practically never publish > 3MP. The Foveon is weak at high ISO and as such would not be my choice. I have seen images of the Merrill and understand for landscape it is amazing. Just not everybody does landscape exclusively.

In reply to:

xmeda: If only usable lens was

"Other lenses in my collection, like my SMC PENTAX 1:2/35, give excellent results, despite the extraordinary demands of high-resolution digital imaging compared for the film that they were designed for. This shot was taken at F4."

then simply buy nice Pentax K5IIs or K3 and save a lot of money having great DSLR .)

I am using a latest Pentax DSLR and have the really amazing 35mm f/2. Your comment is lovely, but sadly only half true.

It is true that the Pentax will give you a superb user interface. It will also give you camera shake reduction as a bonus.

However, the Sony has an EVF and the Pentax sadly does not. Shooting with live-view on the Pentax is great considering the UI, except with no EVF it is clumsy in handling. The Pentax is also APS-C. The 35mm full frame is simply more useful than cropped!

On Using third-party lenses on Sony Cyber-shot a7 / a7R article (495 comments in total)
In reply to:

igor_s: Much the same what I thought about this. No sensor-shift IS, poor ergonomics, not-so-good focus aids implementation. An A-mount camera would be much better for IS and handling, but you would not be able to use any Canon, Konica or Minolta lenses with it (at least for infinity).
Anyway, it Sony offered the Z-axis sensor-shift AF, that would be awesome.

This is a great idea! Never thought about it. Make the rough focus manually and let the camera do the accurate fine focus. I hope any of the camera makers are reading this :-)

In reply to:

Niala2: What did I miss..? I'll ask my question naivaly:
How come the issue of "MODERN thirt party lenses" is not even mentioned? Is it anounced as an other, in depth article?
Is it logic that modern lenses just work perfectly and thats it?
I cannot imagine to be the only one to wonder how for instance Zeiss' ZE/F 35MM f1.4 or 50mm macro, or Canon TS 24mm( all with Metabones smart-adapter) perform on the 7R...

The 35mm f/2 from Pentax is an excellent lens. Very comparable with a Zeiss in performance. There are two images in this Article shot with this lens. You can see this lens delivers smooth bokeh combined with high sharpness. This should answer your question how high quality lenses perform with an adapter on the A7R.

Ah, here is a hint to focus peaking you might find useful. I used focus peaking on the NEX5 and K-30. In all settings I found it to be useless when focusing f/2.8 or wider. At this shallow depth of field it simply seems not to be accurate. I got way better result turning focus peaking off and focus like in the old day with a coarse matte screen. When shifting focus I can see the plane of focus "walking" through the scene. So I stop when it hits where I want the focal point. If not sure I move the focus point slightly forward and backward. After a while you will get used to the change on the screen and identify the focal point. With this method I nail the focus every time with 50mm f/1.4. That is on not moving subjects. As you mentioned, at these settings your own movement can throw your focus already. The above method works very fast once you got used to it. Much faster than using magnification, focus, turn off, adjust framing and then shoot. Hope you will find this useful. Cheers!

@ttbk
I just thought like you until I got in-body camera shake reduction. I could not go back anymore. It gives me 4 stops and I use them!
