Boxbrownie: Oooo great, must dig out all my old enlarger lenses........save a fortune!

And I'll have to try my Pentax DA 40mm f/2.8 Limited with my a6000.

Horshack: I use ETTR extensively on my original 5D bodies. Due to JPEG histogram issues mentioned in the article I recommend that everyone calibrate their camera's raw highlight clipping by shooting typical scenes with varying overexposure and then processing the images in their preferred app to see correlate actual clipping to what they see on the histogram. Another method is with Iliah Borg and Co. RawDigger app; there's a great 3-part article on this here: http://www.rawdigger.com/howtouse/rawdigger-histograms-what-is-the-raw-histogram.

My field ETTR metering technique is to leave the camera on spot metering. I meter the brightest highlight I want retained, which puts that highlight at middle grey, then dial in an exposure +2EV to +3EV above that depend on the reflectivity of scene and the camera I'm using.

Here are some 5D ETTR examples (before+after):

Horshack, your samples are definitely worth 1000 words in explaining ETTR. I will give it a try.

On Hands-on with the Pentax K-3 II article (555 comments in total)
In reply to:

drummercam: Another Pentax, like the K-S2, with an exceptionally accessible opening price point for a excellent feature set. Rugged stuff, too. The advertised claim "the K-3 II also functions at temperatures as low is -10C/+14F" is probably an understatement. I've used the K-3 at minus 8F with no problems.

I have regularly used my Pentax cameras in -40 degree temperatures, for hours at a time. I only had trouble once. I was shooting an event in brutally cold weather, and kept ducking in and out of a warm lobby. Not surprisingly, my K20D started acting up. My fault really, I should have stayed outside in the cold to avoid condensation.

audiobomber: Hopefully the K-3 II review will be written by Dan Bracaglia and Rishi Sanyal. They did a great job on the A77 II review, especially the focus testing. The K-3 was sabotaged by all the wrong settings for the AF-C test.

Clearly Pentax have made an effort to improve AF with the new lenses and with Z-axis performance on the K-3 II. But IMO it is still a very capable system. I am quite confident the K-3 would murder the EM5-II for shooting roller derby.

I tried shooting BIF and sports with AF Hold OFF and there was no tracking. With AF Hold on HIGH, the K-3 sticks to a hockey jersey like crazy. I have little trouble shooting a dozen and more BIF shots in a sequence. I always use Expanded Area AF.

These were shot with the DA*300 and 1.4X TC:

Sorry, Richard, I can see that the word "sabotaged" is inflammatory. I did not mean to imply that anyone deliberately tripped up the K-3. Nevertheless, the settings that were used, AF Hold OFF, SR ON, handicapped the camera such that it could not track.
I don't think I used the word "guessing", but let's face it, there is a lot of guessing when a reviewer picks up a new camera to test. You are not a regular Pentax user, not someone who has owned a K-3 for a year, not an experienced sports shooter judging by the Roller Derby video.

It's entirely possible the K-3 is not up to semi-pro DSLR tracking. but I have shot sports and hundreds of BIF images with a high success ratio. I own an a6000 which is highly touted for its tracking ability. The K-3 is quite a bit better IMO.

PS I am extremely pleased to hear that DPR is working on a better AF testing regimen. You said the same thing about your image comparisons, which are now SOTA. Hopefully the new AF tests will be as fair and useful.

hoxito: According to the "Live View" section on http://news.ricoh-imaging.co.jp/rim_info2/2015/20150423_007349.html (official announcement from Ricoh), there is (finally!) a "Focus peaking" function that can be turned ON and OFF - now THAT is what I call great news!

@ hoxito
There is no focus peaking of any sort in any variety of K-5 (5, II, IIs). The quote you posted refers to video, not Live View. Peaking in Live View acts like any other camera with the feature. Unfortunately FP is limited in video recording as per the quote. I expect the K-3 will be the same as the K-3 in this.

Several previous bodies have had FP in Live View; K-01, K-30, K-500, K-50, K-S1, K-S2, K-3.

In reply to:

KL Matt: No built in flash is a bummer for triggering an off-camera flash without having to lug around a second one. Also, I use mine for fill in daylight backlit people shots infrequently, and it's really handy to be able to just pop it up. Plenty of power for that purpose. The GPS would be way cool to have, but what will turning it on do to battery power? In any case, this camera will likely bring down the price of the K3, which is probably where I'm headed now that the K5 IIs is no longer available for a reasonable price (missed my window of opportunity there).

It is a strange decision. Surely more people use BI flash vs. GPS and Astrotracer. The only way the K-3 II makes sense is if they intend to keep the K-3 in the lineup. The II then becomes a specialty model.

SnakePlissken: Great looking camera and spec. But will it sell? And who will stock it? I have never seen a Pentax DSLR ever and living and working in central London means I see 100s of cameras on the street, tube, museums, galleries etc ever week. I have never seen one for sale in big retailers like Calumet or John Lewis either. I hope it does well as the consumer benefits from choice and Pentax / Ricoh is a great, almost left-field, option to the big guns.

An NX-1 with 16-50 f2-2.8 costs $3,000 CA. That is as much as I paid for both of these kits combined:
•K-3 with Sigma 17-50 f2.8
•a6000 with Zeiss Touit 12mm f2.8 and Sigma 60mm f2.8 Art

The NX-1 has the same DXOMark scores as either of the above and the K-3 matches its sharpness due to no blur filter. Samsung has no lenses longer than 200mm.

Nope, not for me.

I read that the K-3 AF-C test was conducted with AF Hold OFF and Shake Reduction ON. I don't know what other parameters were selected. My tracking settings are AF-C, AF Hold HIGH, AF Expanded Area, Focus Priority.

Plus, the only test that seems to have been made is a bicycle coming directly at the camera. What I liked about the A77 II test was the variety of conditions and settings that were tried, giving a more balanced conclusion (good for this, not good for that).

A Ricoh executive commented on the pixel shift technology at CP+

Pentax Forums: "Would it be possible to leverage the SR mechanism to increase the effective resolution of a Pentax DSLR?"

Ricoh: "We have tried to increase the effective pixels with shake reduction. But the data size is big and image quality is not improved. So we are now trying to improve the resolution performance without increasing the effective pixels."

"now correcting for a claimed 4.5 stops of shake, compared to 3.5 on the K-3."

This is not just a Pentax claim. Both of these figures are rated to CIPA testing standards.

On Nikon D5500 Review preview (326 comments in total)
In reply to:

koolbreez: From looking at the comparisons with the D5300, the only useful thing upgraded is the battery life. They both use the same sensor, and processing engine, so no difference in image quality. They both have the same resolutions, although the high end is listed now as regular instead of extended, which actually means no difference. Buffers are the same, shutter speads are the same. The GPS has been removed, and can't be considered an upgrade, even if people didn't use it. So how can this review state that the D5500 is an upgrade in every respect, when only one useful item has been upgraded? A better grip? There never was a problem with the old grip contributing to shaky images...lolol. This simply looks like a review to sell cameras, not print the real truth. As more time passes DPReview gets less and less reliable.

Guidenet, I'm not sure if you haven't read the posts above, or whether you haven't understood the discussion. We are objecting to the blatantly misleading statement in the review, i.e. that the D5500 is "upgraded in every respect". In reality, it is a mild iteration of the D5300, better in a few ways, not as good in a couple of other ways, but mostly the same.

Is the sensor upgraded? No
Is the viewfinder upgraded? No
Are the controls upgraded? No
Is the flash upgraded? No
Is the body more rugged? No
Does it have the AF motor its predecessors lacked? No
Is AF upgraded? No
Is video upgraded? No
FPS upgraded? No
Is GPS upgraded? No, in fact it's gone.
Upgraded in every respect? What a sick joke!

I agree, that statement is nonsense (or worse, marketing speak) and should be removed immediately.

Andreas Stuebs: I would have liked to see how this camera stacks up against the Pentax KS2.They cost approximately the same in Germany.

KS-2 advantages are weather seals, front and rear wheels, 100% coverage pentaprism viewfinder, in-body focus motor, IBIS, adjustable blur filter, larger buffer.

nerd2: We are waiting for LARGER sensors, not high resolution sensors.
I am in love with fuji OOC jpg colors and really want to see a7 equivalent from fuji.

Also X-trans is just a marketing BS that barely adds anything - fuji just overrates their ISO values to give a false impression of being 'cleaner'. Oh olympus is doing the same thing.

> we've updated our Raw exposure methodology.

Rishi, can you please explain how the methodology has been changed? Is it fair now to compare different systems at the same ISO?

In reply to:

PatMann: Best of luck to Fujifilm on addressing these issues. The lens lineup is stellar - no other APS-C system comes close. But AF and resolution do need to be addressed. If Nikon produces a pro APS-C camera to replace the D300s, they need to bring lenses with it to sell it. If they do, I will probably stay with Nikon. If not, Fujifilm is the first place I will look for my future primary camera system. I can't afford the $ or the overall system weight and bulk to go whole-hog full-frame.

> "The Fuji lens line up is pretty decent."
Yes, it is, but not complete. Note that "pretty decent" is nothing like saying:
> "The lens lineup is stellar - no other APS-C system comes close", the original statement I challenged.
