Is Canon Beginning To Fall Behind?

I do think it is more supply and demand. Canon is the biggest camera brand and so there are apt to be more copies of any lens available in multiple mounts available in EOS mount. Sony and Nikon have significantly smaller shares and so I am sure that Sigma sells fewer copies of those mounts.

Pentax is in an odd position where they have such a small section of the market that if you are selling something it may be tough to connect with a buyer interested in what you are selling, but there are also a lot fewer copies available on ebay at a given point in time.

K-1 mkII , a step back?

You made a comment in another thread saying that you thought that noise was a bigger detractor from images than the slight loss of detail. I thought it was a very astute point, but now you seem to be back tracking.

Biz-engineer is right. Situations where you can use a tripod, you can use as low iso as you want. Situations where you can't, you often end up getting into the iso 6400 and 12K range and that is where I have seen improvement. If you are really good with noise reduction and don't mind taking the time to work with it I imagine you can get fine results with a K-1.

Honestly, I don't shoot a lot of high iso except in places like museums or when taking photos of my children. Landscapes I am always at lower isos. My wife on the other hand shoots weddings and if it is available would use a lot higher isos. Receptions are often pretty dark. No one is going to blow those photos up to huge sizes and so slight loss of detail isn't a big deal, but the reduction in noise is.




Any differences that you see below iso 600 are going to be due to copy variation between cameras or RAW development tools. There is no difference in the camera sensors themselves. If you got two copies of the original K-1 and compared them, you might think that you had found differences in performance, but at most they would be slight variations.

Overall, look at the accelerator as having about a stop improvement with regard to noise reduction with a slight loss of detail. That's all. Is it a huge difference? Well, it lets me use iso 12K without too much problem, but as you pointed out earlier, it isn't enough to allow 51K iso to be usable. So, one stop with a slight penalty.

And the K-1 II does offer some improvement in AF tracking and hand held pixel shift. But there are plenty of folks for whom the original K-1 is a better fit. You are probably one of them, but honestly, Norm, pixel peeping doesn't become you. :)

This sort of thread is disappointing to me. Because it misses the point of photography completely. I currently do own a K1 and K1 II. The difference is that the K1 II high iso images do look cleaner without noise reduction compared to the K1 images. Was it a revelation? Not particularly. But the "loss of detail" is pretty minimal too. Have I taken a bunch of photos side by side with the K1 and K1 II? No and I don't really plan to do so either. They both work well and I like them both a lot.

The photo below is iso 6400 1/125 second brightened 1/4 stop in Lightroom. Shot with the DFA 100 macro at f2.8. Is there loss of detail? Perhaps, but how would I know, because I didn't shoot a K-1 image at the same time and my daughter probably would have moved before I could have exactly reproduced the same image. But I'm pleased with the image and any loss of detail doesn't detract from it. At the same time, to use the K-1 in this setting would require a bit of noise reduction which would probably remove detail as well. But it took me a lot less time to process this image.

To me, contrast and transitions from in focus to out of focus are more important than sharpness. Using pixel shift, I can get a lot of sharpness out of my lens, but I do feel as though the flower example at the beginning is a bit over sharpened for my taste.

Fenwoodian, I would just say that your strawberry photo is very nice, but probably suffers a bit from being shot at iso 1600 and doesn't have as good depth of field as it could have. As others have said, either focus stacking or stopping down more helps by increasing depth of field. But certainly sharpness isn't the be all or end all of making good images.

There is less value to shooting with a K-1 (or any larger sensor camera) if you insist on using straight of camera jpegs. The beauty of larger sensors is what you say -- there is more information there. But that is only realized through bumping shadows, dodging, burning and selectively sharpening. To me, part of post processing is flattening an image to the point that it can be revealed fairly easily on a normal screen or print. The detail is there, but even good jpeg engines don't do a very good job of selectively adjusting your image.

This is nothing new. If you read Ansel Adams' trilogy of books, you find in The Negative him giving detailed instructions as to how he developed images in order to maximize their impact. He certainly was a good photographer, but he kept copious notes on how he wanted to work on each negative to get the most out of it.

These aren't great photos, but I thought I would share them anyway. Yesterday morning I looked out my back window to see a mother bear and her year old cub wandering around my backyard investigating my peach tree and garden. Unfortunately, the longest lens I had handy was the DFA 100 macro which is definitely not a "bear catching" lens, but I made do with it. My wife had the DFA 70-200 in a bag somewhere for an upcoming wedding, but if they come back I'll try to use that (I'd rather they didn't come back -- my garden is pretty happy without bears in it).

Cub.

Pixel Shifted Images

The whole thing is that dynamic pixel shift lets you shoot pixel shift hand held. All great, but the thing is that I don't know of any raw developer (including Pentax's own DCU) that will develop more than the first raw image in the DNG files. If your options are to (a) develop the first image shot or (b) shoot a jpeg then I would rather just shoot a single RAW image then shoot a dynamic pixel shift image that can't truly be developed. I shoot regular pixel shift all of the time and as you say, develop it with Raw Therapee into a 16 bit TIFF image.

It should actually help brick and mortar stores with a local presence. It is rough for someone who has a store in your community when you go in, check out a product in store and then order it online to avoid paying sales tax. Beyond which, a lot of states required the consumer to list on their taxes all large internet purchase and pay sales tax on them after the fact (not that anyone ever did that).

Not to get political, but in the end, state revenue has to add up to enough to pay for services provided by that state. States with a lot of resources like Texas and Alaska don't need much tax revenue. States with fewer resources need tax revenue and then it is a question of how you divide up those taxes (sales/property/income/gas/corporate/etc).

I always felt sorry for local businesses who ended up losing business just because you could avoid taxes on the internet.

Mabry Mill (Pentax K-1 II/DFA 24-70/Traditional Pixel Shift)

Mabry Mill by Vincent1825, on Flickr

By the way, has anyone figured out a way to edit the dynamic pixel shift RAW files after the fact? The only thing I can see is that you can shoot jpeg, but that feels like it throws away a lot of the benefit of pixel shift.

I agree for the most part. The biggest negative of smart phones have to do with ergonomics. Having a light flat object held a little away from you is uncomfortable. The buttons are not easy to activate (I don't really like touch screens).

Accessories are another issue. Sure, you could probably figure out how to use a bounce flash with one, but it sure is a lot harder than just sticking one in the hot shoe of an ILC. Tripods are another thing that are tougher to use with most smart phones.

As you mention, you are stuck with the lens that is on the smart phone. You are also unable to use filters easily, I would add. GND/Neutral Density/Circular Polarizers are all things that I use pretty frequently. Tough to use on most smart phones.

The final thing is that they just don't do very well in situations where (a) you need a lot of dynamic range and (b) need to shoot high iso. My experience with smart phones (at least with straight out of camera jpegs -- I haven't used RAW on my iphone 6) is that they default quickly to HDR and even there, they struggle to capture anywhere near the dynamic range I could have gotten with any SLR I own. They bump up saturation and over-sharpen images out of camera and the end result is images with a bit of pop but that can't be processed much after the fact.

It may sound like I hate smart phones but I use mine a lot for snapshots. I just don't see them taking the place of ILCs for most serious photographers. Could use one on a portrait shoot? Sure, but the idea of shooting a wedding with one sounds miserable to me, even if it could be done.
