here's an interesting story.
Instead of the color filters used on typical Bayer or other patterned image sensors, this is a color-splitting method based on diffraction within the sensor surface.
This could utilize significantly more incoming light to create electrons for readout signal.
Overall increase in effective QE and SNR possible.

IMO, This may be a method better suited to tiny pixels in small sensors rather than larger sensors and larger pixels in higher end cameras. Either way, an interesting and promising development.

Just saw this on some other sites tonite.
They've been making lots of wide zooms but i haven't seen a new medium long since I can't remember when.

Nothing on Tokina's site yet.

Looking fwd to test results.
Canon's and Nikon's offerings are already pretty good but there's still some room for improvement.

Canon is really stupid they should lunch the 7D mk2 before Nikon lunches the D400.
we'd LIKE a 7d2 now
but whoever blinks first and intro's their product lets their competitor have an opportunity to release something better which will affect them for the next few years.
I suspect Nikon will have to play their card first.  The D400 is grossly overdue but if it is as relatively good as the D800 was they won't have much to worry about until the next update in a few years.

They better hurry up though, because otherwise Nikon's going to pull ahead in the consumer market w/ the D5200.  No matter how true the "Megapixel Myth" may be, the majority of casual consumers who want to just step into a Rebel or x0D+, model is going to think the Nikon is 33.33333333333333333% better for the same $$$ w/ 24MP.

That's also true, timing is likely more competitive in the prosumer market than consumer market where new products are introduced much more quickly.
D5200 is no workhorse from what I can tell but it already has IQ that blows away anything Canon's released yet in the crop sensor arena.  Gives FF a good run too.
So in this case, those 33% more MP do equate to more imaging power.  Not that the vast majority of users will ever notice with how they use their images.

Geez aglet. Why u no shoot all nikon already?

Because I still like Canon for some stuff and I'm starting to like Pentax more too. :)
Not so crazy about most Pentax glass but there's Tamron, Sigma and others to fill in the holes.

And some sweet piece of Fuji's caught my eye and is flirting with my wallet.  I'll be coy with that one.

But most of my shots lately are rockin' w nokiN.
Canons get used for more studio or other controlled lighting kinds of work and I'm still experimenting w Pentax.

Have you tried a Pentax?..  Raw file quality of Nikon with a great amount of customization available and a really easy to use user interface that rivals Canon and Panasonic's.  I sort of understand why Pentax users are so enthusiastic about their platform - it's nice to use.  I'm really enjoying playing with it and can see it doing some really good work for me.  Not much to choose from with them but what's there is pretty good.  And they're thinking of a FF body.  That could be very interesting.

Aperture is not my choice at all, used Mac since digitalization/ film scanners etc.
If you have Canon why not test DPP, canons raw program  , free of charge

I tried Aperture, having liked and used Mac OSes and SW since the first Macintosh in the mid 80s.
Aperture did nothing but crash, I couldn't even get started with it!
OUT IT WENT. Won't even consider it now.
Also holding at Mac OS X 10.6.7 or older 10.6.8 as latest 10.6.8 was warped; 10.7 and 10.8 suck harder with every update.
my system is now frozen because it works the way I want it to.  no more updates.

to summarize, I was a Canon fanboy for decades and justifiably so for a while when Canon's DSLRs were leading the performance curves.  When I became more disappointed with newer Canon body performance compared to older Canon bodies and newer competition, I migrated towards the tools that do what I want, how i want.
I like them all!  The good ones at least. :)

the long story

I always like cameras, got started by borrowing my older sister's AE-1 in the 70s and having fun putting interesting shots on her film w-o her permission.
Got my own A-1 2nd-hand in '81, along w a few lenses. Shot for fun, shot weddings (hated it), shot some local fashion and event work.  Didn't have as much fun as a photographer as I thought I might.  Altho as a young man, being around a lot of lovely young ladies parading in strange outfits had some appeal.

Got a real job in my preferred area of technical expertise a few years later and then shot just for fun with the same Canon gear I'd always used.
First digicam I tried was a Canon A20 - the immediacy of the method had me leaving my A-1 on the shelf a lot after that!  The little camera was fun and easy to use so I started pushing its limits. That took about a week. A40, A60, Panasonic FZ20, A610 and a whole lot more I can't remember.  Didn't go DSLR when they came out because I couldn't justify the cost at the time. 

Nikon, Pentax, and others never even entered my mind yet.

Got a used Canon G3 compact somewhere along the way and WOW!  This thing really performed for IQ compared to the PnS types.  Started thinking about DSLR quality...  All my film was past its best before date now.

Friend got a 20D. I was envious but resigned to not buying a DSLR until they had at least 14bits/pixel and that live-view idea was also interesting.

First DSLR was Canon 40D (still have it) and it was AMAZING.  IQ and all the features really got my attention.  What the camera could do in raw reminded me of what I could do with film and paper in a darkroom w-o the smell and hassle.
Some I knew had Nikon before that, was not impressed with the ergonomics or user interface.  Canon DSLR and PnS were all very intuitive to use.
Fun and creativity returned to photography for me.
Went thru a whole mess of Canon Rebels, just kept them mounted on lenses cuz they were so cheap used.

Nikon and Pentax, still not on my radar tho close friend had D300 and loved it.  My 40D was comparable enough in IQ, I was still satisfied, maybe even smug about being a Canon user.

Nikon D70 at work, hated it, really clumsy interface.

5d2 came out, lots of hype.  I bought into it.
Most massively disappointing camera I ever purchased, raw files at base ISO were obviously noisier than my old 40D and even the Rebels.  I was led to believe, and had expected, much better from 5d2.  Fanboys were too busy raving about its virtues to see the flaws I found in the first few hundred shots.  Barely used it.  After 3+ years I sold it for half what I paid, cursed every fantastic scene I shot with it because post-processing was very limited.

Avoided 50D - was obviously too noisy without even trying it. What was happening?!?
60D, liked it, bought 2 of them.  Still have one, main everyday camera.

7D for wildlife with long slow lens, good camera but again, more disappointing low ISO performance. Sold it recently after a few years of light use.  Got some excellent shots with it, loved-hated it.

decided I'd better put my tech expertise to some use and learn more about imaging systems
Discovered Nikon (D90) and later Pentax (K5) were starting to really perform well in low ISO range I like to use.

Tried a D5100 because it was cheap and comparable IQ to D7000 which I didn't like the ergos on.
Astoundingly great IQ!  Bought pile of nikon lenses, new and used.
D800 - sounded very interesting, waited for test results.. I have to have this!  I have 2, love-love them.
Bought more cheap D5100s to use as back-caps on favorite lenses.
Started selling off Canon gear I wasn't using any more.

Bought a couple Pentax bodies... strange-love them!
Considering Olympus (OMD-EM5) as it feels good in hand and performs like 60D or better
Considering Fuji (X20 to start with) because they're niche and pay attention to detail and do things differently.

All my remaining Canon bodies are now older Digic 3 class... they just perform the way I prefer and need.
I'm considering a 6D, and hoping for a low-iso-improved 7D2 to put back on my long glass.

Meanwhile, I'm enjoying Pentax more the more I use them and, along with the Nikons, I get the kind of high quality raw files for my way of working with images that Canon no longer provides. (6D and 1Dx possibly marginal exceptions)

I'll use whatever is the best tool for the shot I want to take.
I'm no longer a Canon fanboy, just a camera fanboy and I love to shoot with equipment that I know won't disappoint me when I finally get to spend some time rending the raw files to create the final look I'm after without a lot of photoshop work to compensate for shortcomings of the initial image capture, no matter how hard I want to warp that raw file.
This is a great time to be into photography.  Even perfectionists can find something satisfying to use.

Software & Accessories / Re: Noise in Lightroom vs DPP
« on: January 26, 2013, 02:29:02 AM »
..The main difference I see in the posted jpegs is that the lightroom image is much brighter, inndicating that settings are different between the two.
That DPP image is a stop or so darker, which will conceal a stop or so more noise....

It looked like that to me too until I pulled out my little RGB screen sampler and the same parts of each image are very close in RGB values in the darker areas. (taken from inline images, too lazy to download them)
The lighter areas ARE a bit different so there's a different curve/contrast function happening and the different cropping and accutance make another perceptual difference.  Noise is more noticeable in the darker areas, per usual.

I'd much rather keep detail and accutance at the expense of almost any amount of luminance noise, but chroma noise just bugs the S___ out of me.

for now, anyway, and likely for a long time to come
That's gotta make y'all happy if you bought one. :)

The Tamron would suffice for me for what I'd use it for and how I'd use it.

looks like considerably different levels of sharpening applied, not sure how you measure them being equal.

more sharpening in LR is accentuating the noise but it's not so bad it can't be tamed with a little bit of NR

LR is well known for it's better NR ability, especially chroma
I still use DPP when the shot does not require much tweaking as I prefer the look of it a little more than other raw converters.

and when you're up at 12800 ISO, you're gonna see noise, especially in the darker tones, that's just the reality of physics.

Aperture is cheaper and probably a more logical progression from iphoto, however lightroom is more fully featured and adobe are more on the ball at keeping their raw codecs fresh (important if you are buying a new camera) there is a third way, which is photoshop elements.

If you are happy to do the heavy lifting as raw and save as jpeg then elements is great value.

Why not install and use the FREE DIGITAL PHOTO PRO that comes with your Canon camera?!?

It's an excellent piece of software for what it does, which admittedly is limited.
But it will allow you to play with your raw files, make adjustments to exposure, white balance, color, contrast, etc.

With it you will learn to appreciate the amount of post-processing latitude a raw file provides.
DPP also provides that "Canon look" better than the other software and I find that it can also wring the most detail from a properly exposed raw image as well.

LIGHTROOM is an excellent next step, does an awful lot of more creative things than DPP.  Can handle hi ISO noise much better and will take you to the next step in image processing.

My workflow includes DPP, Lightroom, Photoshop, DxO, Graphic Converter (Mac only) and occasionally other specialty software.  before I had all this I used DPP as my main raw converter and it did a great job.  Canon is always updating it and it's been kept free so far so install, update, dive in and have fun learning! :)

EOS Bodies / Re: Which is better? 5D MKII or 6D?
« on: January 24, 2013, 09:10:58 PM »
The 6D is a slightly-microwaved 5D2 and re-served to us canonites for the next 4 years.  ;D


6D does have MINOR IQ improvements over the average 5D2:

- base ISO FPN is improved
- hi ISO is noticeably superior
- center AF point is better in low light
- love that quiet shutter
- intro price isn't horrid

BUT - the midtone fixed pattern noise I found on my 5D2 is still present, if reduced, on the 6D I tested - a minor but there it is, possible issue.

There's likely a few points in the 5D2's favor, like build quality, but I'll leave those to someone who likes the 5d2 to state.

EOS Bodies / Re: Any news on the 7dMk2 now that CES is done
« on: January 24, 2013, 02:22:30 PM »
just read another bit of japanese translation interview and it's typically vague, even on top of the usual japanese language + pre-show ambiguity.
saying the 7d2 isn't the story of the day likely means it's not going to show up at CP+
it could mean something else will hilite the event (new sensor tech?) which may eclipse the 7d2 announcement which is alleged to be an incremental upgrade over the 7d.

We'll know what Canon wants to pry our wallets open with next soon enough.

..I can't see Canon doing Sony and Pentax's trick of making a body that takes SLR deep flange lenses with no OVF. If they make a 7D mk II, it will have an EVF.

speaking of which, I've been playing with that Pentax duck of a camera, the K-01.
It's image quality, even for a 12b raw file, exceeds the 7D I had by quite a margin because of the much better noise characteristics.
It's kind of fun to use if you're not in a hurry as it focuses as slow as an old PnS cam, which it essentially is, with interchangeable full-size lenses.

Fuji's made some very fast focusing new cameras so it's not impossible for Canon and others to do so as well.  Get rid of that mirror and you suddenly have a very high frame rate possible too.

It'll be interesing to see what tricks make it into the 7d2 but if it ends up as a mirrorless, it better not be a step backward in ANY way or there will be howls of derision around the world.
I'd say that odds are good a 7D2 will remain an SLR with a nice big OVF.

EOS Bodies / Re: Where are you EOS 70D?
« on: January 23, 2013, 11:25:44 PM »
No! Stop! Canon no! For the love of every thing that is precious in this world, do not release another camera with that same sensor! I have been waiting for eons for a new APS-C sensor in a semi-professional body! Will I have to wait another two more years? I don't have the budget to buy a 7D mkII and I have been saving for this precious little thing the 70D. Please don't screw it up.
if the only thing a 70D gets is 60D tech + GPS and WiFi it's OK as an upgrade for some but not those already with a 60D.  Still the 60D's sensor COULD use a little improvement in noise performance at low ISO and, if they make the 70D low ISO noise performance as good as the new 6D's, it's an incremental upgrade in file quality.
I think they're trying to get some sort of record for wringing the most profit from a sensor, over the longest lifespan
That's business.

So for all your talk you can't post one image that demonstrates the totally unusable files you regularly got from real world shooting the 5D MkII? Amazing...........

I've got more important things to do this week than appease your impatience. :P
In the meantime, start formulating how you will describe that the banding i've experienced with my 5D2 is my fault. ;)  Especially the upper midtone range.  I really want an explanation for that one. [/cheeky]

And then outline how I can fix it with advanced PP skills.  i know you are good at this so hopefully you will share some of this knowledge with us.  I'd like to improve some of the shots that I otherwise like but have these little flaws that annoy me.

When I have time to prep the samples I'll be starting a new thread in this section.

Now I have to go retest a Nikon camera that they've serviced 3 times over 4 months and have made only more problems without addressing the initial one.
I'll give them that, Canon service in my area has been FAR superior to Nikon's.
