frankje: “Which camera should I buy?”
Can’t you call this item in future roundups something like “Our choice”? Would be more realistic.

It is possible the being 'Eric' missed a key stroke when making the account.

In reply to:

spencerda: Forgive me if these questions have been answered.

1) Can the pixel shift feature be translated in numbers as far as increase resolution vs the 36mp sensor in standard mode if so are there any formal numbers?

2) Does the crop mode which I understand gives 15mp surport pixel shift?

Dave

Yes, the crop mode supports pixel shift.

Don't think of crop mode as some special arrangement of the sensor that may or may not support other features. The sensor does all its normal sensor stuff even in crop mode.

However, in crop mode quite a wide border of sensor area is disregarded when the file is saved. It is just the same as editing an image where all features of the editing software are effective.. and then cropping the heck out of it :^)

Tan68: I haven't looked into Silky Pix in years, but their front page has this, "The partial correction is equipped, so that the professional edition realize a more delicate photo of adjustment.", and I like reading that.

The Pentax DCU allows pixel shift images to be saved as 16-bit TIF. This should be a good start to take into an image editor of choice. DCU has few features but it may be possible to make some gross adjustments before exporting.

The Silky Pix software is about US$ 260...
I suppose I will use the Pentax software and then finish up with Capture 1. Perhaps C1 will support non-MC pixel shift files but so far haven't and I wouldn't expect them to start now :^)

+ owners of bundled software such as DCU are offered upgrade pricing and this is 40% less than purchase outright.

I did try Silky Pix not-pro version and it produced output better than DCU. I could probably fiddle with DCU for better output, but what I can get with little trouble mostly guides my efforts..

I made additional comments here:
http://www.dpreview.com/forums/thread/4011755?page=2#forum-post-57873355

If I go this route, my plan would be to use the SPix software to create a 16-bit TIF to finish in C1.

The not pro version is $90 for upgrade.

The greatest difference between pro and not looks to be editing selections or masks [now I understand the quote on the front page, above] and curve with luminance only adjustment (a good thing).

If a user owns another software that does these things, the not pro version of Silky Pix is satisfactory.

Whether the SPix performs pixel shift image manipulation better than the Pentax DCU is a question I have. I would suspect not..?

Perhaps the SPix tools available would allow an output closer to 'finished' than the Pentax DCU so that less manipulation of the exported 16-bit TIF would be required in other software...

Looking at the DCU software interface, I think $50 of that $90 would be worth the SPix interface alone...

Raist3d: DPreview - Please DO NOT say -> "And, at least for Mac users, SilkyPix is not the most stable or easy to use software out there. "

This may be true of the *version* of SilkyPix bundled with the K-1 which is unfortunate. But the Silky Pix Pro 7 which I am giving a trial on Mac is actually pretty solid so far at least doing the regular conversions (haven't tried in-heavy spot editing).

One great thing about Silky Pix Pro 7 is that it supports virtually all the changes made for Fuji, Panasonic and Pentax. In fact, I am rather impressed with the high ISO performance on Silky Pix Pro 7 which competes to my surprise with DXo's 11 Prime.

A form of dynamic balance is required...

One runs across the rocks in a stream and arrives to the other side triumphant. The hiker that stops midstream to consider which rock next gets wet.

Open the file in either DCU or SPix, thrash through your edits, save, and close. ta

22codfish: All current production Pentax cameras and lens are WR or AW (weather resistant).
This includes the Pentax K-1camera and the lens used in this report.

"The weather conditions were, well, pretty miserable. My fiancé and I experienced moderate rain throughout most of the day which definitely put a damper (literally) on the trip." Now we need WR photographers. :-)

Many of the currently available lenses are weather resistant but not all are.

If a user is interested, they should look for the WR or AW built into [included in] the name of the lens. I really don't remember which is better.. I think WR.

I know DA* (crop lenses) are WR.

I presume the new DFA* are WR as well but am not certain. I imagine the new FA zooms are WR but really haven't looked into it.. I have little interest in those lenses :^)

Edgar_in_Indy: Maybe you could test the pixel shift on the swirling water as you flush this bad article down the toilet.

You wouldn't want to use a gray water camera from certain other regions.

It is too easy to fall into the trap of using a camera tuned for water swirling left in a rightly swirling market.

In reply to:

fatdeeman: Does the movement correction cancel out the benefits of pixel shift in the areas of the image that require correction?

Yes, one RAW file is created when pixel shift is used. The RAW file is quite heavy because it does contain the infos for the four images. The file will be about 4x the size of a single RAW file.

The Pentax supplied software, Digital Camera Utility (DCU), does what it does and the pixel shifted image may be exported only as either JPG or TIF.

DCU is not very.. feature rich and 'utility' is the perfect name for it :^)

I am disappointed it is not possible to 'flatten' the heavy pixel shift RAW into one typical RAW image. Perhaps it is not possible, but Pentax allows me to take multi-exposure images and save those as one RAW...

Either way, there is much that can be done with 16-bit TIF. If I end up with an image I would like to work on in my regular RAW editor, I will see how dcraw manages things. Perhaps it will be possible to 'bake/flatten' the P/S image from its payload of 4 RAW images and export a RAW file.. I hope so !

In reply to:

siggo: Good start. Now would be the appropriate time to establish a policy to include use of bundled software in all reviews. Use third party (Adobe) as well if you wish to show what might be achieved, but learn from this that review should always reflect what the customer would receive.

I don't think supplied software needs to be used to check results with each new camera.

An article about supplied software could be helpful to some users. Some user do use the supplied software as a matter of cost savings.

I don't think an article like this would need to be a comparison with a winner. Some screen shots and explanations of basic features and file management would do.

tar4heel2: ARRRGGHHH!! Make the RAW file available and let me run it through Capture One and DxO. I'll give you the run down on these files in 30 minutes.

I don't know about DxO but C1 doesn't support pixel shift. Right now, the software will not even open PEF RAW but will open DNG. Support for PEF will be added, of course. Anyway, Even with support for PEF, I don't think C1 will read the pixel shift file.

In reply to:

fatdeeman: Does the movement correction cancel out the benefits of pixel shift in the areas of the image that require correction?

I think the benefit of pixel shift is canceled out in areas where correction is applied.

The motion correction function looks for motion, of course. If motion is not found, then the pixel shift composite image is created using all 4 images. My understanding is that if motion is found, then only the first image is used to create that portion of the composite.

So, immobile rocks would receive the benefit of all four images while fluttering birch leaves would not (the area surrounding the leaves would be whatever was captured in the first of the 4 images).

I believe there is a way to extract that first image from the single large pixel shift RAW. I think this can be done with dcraw.. but I am not sure and only mention this as an option to explore. With the first image extracted, it can be combined with the pixel shift image developed Without using motion correction in something like PhotoShop. Then, the user can mask areas as they please to remove motion artifacts.

Peiasdf: Good showing consider the possibly faulty lens.

What I am more excited about is the possibility of SONY adding pixel shift to A7RII. No mirror shake, E-shutter + superior lens would make A7RII more Godzilla than a beast.

History has shown again and again how culture of pixels is the folly of men. I say it has to go. Go, Gojira.

reptile9985: Once again Sony shows how they can make the best sensors but can't use them properly since both Nikon and Pentax can achieve far better results with the very same sensors.

I would buy this if it could mount tamron lenses, the very same pentax lenses are too overpriced.

Of course it mounts Tamron lenses :^)

Or, you may mean you wish there were more Tamron lenses made with Pentax mount.

It is true that many lenses by Tamron as well as some by Sigma are not manufactured with Pentax mount.

photofisher: I can't decide between hipster grey and hipster brown. Maybe I'll get one of each so I can coordinate with my shoes.

You just dissed 3/4 (.75 in the metric scale) of my clothes... what shade of gray is hipster? Don't tell me there are 50.

I prefer Hobbit brown and Elven gray..

N13L5: If you don't mind a constant skeletal, muscular imbalance while walking about with your (usually weighty) gear, by all means, get a messenger bag.

Well if you always just shoot out of your car window, with the bag on the passenger seat, I see no problem either.

But if you like to hike places to get the exact pictures you want, don't get any bag with a strap for only one shoulder.

this is true.

it isn't so much hiking as the time. i understand you mean hiking to include longer periods of time and not only distance or elevation gain. walking around town or standing are just as bad.

even if the weight is bearable, over time carrying things this way can cause trouble. camera stuff is not light.

+ remember, all Indiana Jones had in his pouch was a scroll or a gem the size of a fist or a gold medallion or some dates. i don't think he ever tried to carry all those things at once.

RedFox88: You should correct your article. You wrote it so why the "what WE like..." and "what WE don't like...." at the end?! It needs to be "What I like about it" not "we".

I suppose 'we' reflects staff at DPR, although not all staff will have participated in the review. Read it as 'we at DPR'...

I doubt 'we' is intended to have incorporated your personal preferences, Mr, Fox.
