On article The Sony a9 is a 24MP sports-shooting powerhouse (1810 comments in total)

Wow! Nice specification. I can't wait to read how this camera performs. There will likely be an A9r as well, but I'm worried where the price tag for this type camera is headed. The new lens (100-400) is interesting considering how it might work with the A6500.

I remember being fairly vocal about issues I saw with the original A7R on Sony forum. Now the A7RIi has a stronger SS mount ring, can record uncompressed (at least not lossy) raw files, incorporates IBIS with OIS (as good as Pentax SRII, IMO), Has a completely silent & vibration free GES mode among many other improvements. It has become my number 1 camera.

Wha? Interesting post, DPR. Everybody wait up while I put some popcorn on. :^)

Petroglyph: "The launch of the D7500 presents an interesting quandary for camera buyers: should I buy the D500 or save some money and get the D7500?"

Answer: Samsung NX1 released in 2014: 28.2MP bsi sensor, shoots at 15 fps, records 4K to the sd card in h.265 codec. 1498$ I thought the rest of the industry would catch up in a few years. It seems like a little retrenchment.

Tbolt47: And it looks as though the tech will never be there, at least from Samsung. IMO, it is still the most advanced aps/c, even after 3 years. Too bad Samsung quit making cameras as they used to force the big makers to lumber forward a bit. Now the bigs can sell re-marketed specs. Two steps forward now two steps back.

As far as Pentax goes, I think they have already taken action to stop the line of Pentax Q system. Tiny mirrorless cameras with leaf shutters & IBIS. No EVF though. This means they reduced the number of mounts they support to 2 (645 and K). Seems like there was also a restructuring in the Americas and Japan which reduced staff. Next year if they return to profitability from the camera division, problem solved. Otherwise?
This is similar to Nikon reducing the number of camera lines they offer.

Josh Leavitt: If the 44x33 100MP BSI sensor currently in development is expected to launch in 2018, then I'm assuming it's going to be featured in the next Pentax 645 model. The Z rolled out in 2014, and the D in 2010, so 2018 makes sense for a new generation.

You could be correct. But the rumor a few weeks back was that Ricoh had inked a deal for a 55 X 41 sensor in excess of 100MP to be featured in a new MF camera. Maybe 645Z II. The fact Sony is making a couple of those types is interesting information. There wasn't even mention of Pentax in the article though unless they went back and amended it. :^)

"..., our consumer Digital Imaging business will move under Panasonic Appliances Company and is not being dismantled."

The good news is, now the NSA can watch you in 4K from your toaster while you stumble around in the morning making breakfast. :^)

Well the industry was showing a lot of innovation recently I guess now we're in for a period of slower development. Canon and Nikon might feel less pressure to innovate from the others. That's a shame. I also hated to see Samsung get out of the camera business.

In reply to:

jaxson: Video Stabilisation is utter rubbish in my experience. Warps the image in a non linear way which can't be recovered in post software. Definitely not real IBIS SR being used here.

FYI if the stabilisation option is called "Movie SR" then it's not real sensor shake reduction. Pentax had this working on the K-x / K-7 and K-5 models, but walked away from this, right when it was the next best thing from Panasonic, Olympus and Sony.

"Thankfully, the also features 'Movie SR', smoothing the shake from shooting video handheld. We aren't certain if the stabilization in movie mode is electronic or if it uses the sensor's stabilization or a combination of the two, but the result is impressively still handheld footage."

I don't think so.

Before they had a massive form of M-JPEG near as I can remember. Like an avi container with M-JPEG or a lot like it anyway. No jello effects there because it is like a series of photos with no interlacing or blending. It is very easy to edit in post but the files were enormous. I think the old version of physical SR would have had an easy time stabilizing it. But Ricoh engineers must think the SRII can do a decent job of physical stabilization of h.264 files even if compressed and possibly interlaced or blended. It could be a really cool video upgrade, we'll see. If it's good they can call it in-body steady cam. :^)

In reply to:

samfan: It's just gorgeous. Pentax nailed what Nikon was trying to do with the Df and screwed up.

Well, almost. I with they'd finally upgrade their 4-way controller to something more modern and that fat border around the LCD is a bit odd.

Either way K1 and KP seem like a killer combo as far as camera bodies are concerned, at least if you like the retro-ish SLR looks like I do.

Heh, this has to be the first time I really like a camera for the looks and barely think about the insides. Okay, second time as I had the just as gorgeous Pentax i-10 compact at one point too. But this one is certainly also a decent camera on its own.

vscd: CIPA 390 means turn off the LCD and get 700. Or get the battery grip and put the larger K3 battery in it. Or keep a spare in a pocket like I do with any mirror less camera I might be carrying.

I don't think so.

Those K-5, K-7 models also had an older codec. The FW update that brings physical stabilization to H.264 codec files in the K1, & KP might require the new SRII unit to work effectively. I'm not sure but am interested to see what they do.

On article Pentax KP sample gallery (95 comments in total)

Nice gallery. 18-35 works well on there. 35 macro ltd is fantastically sharp as always. ISO 25600 shot was excellent with regard to noise handling, I think it would print well. 20-40 looks like a lot of fun and offers a good look to the images. 16-85 is a nice lens. I hope DPR will try the 55-300 PLM during their review of this camera. I've seen some ISO 6400 shots from this cam on the net that look very nice. I agree the DA limited lens series is right for the camera though. Maybe throw in that Sigma 18-35.

In reply to:

citrate: I thought T-stop number should be used rather than F-stop number, when we are talking about light transmission in low light.
For example, the Canon 85mm f/1.2L you talked about is a T 1.6 lens.

Correct. The more the lens to air surfaces (number of elements/groups) the lower the light transmission. I wonder what the T-stop of those giant new 'Art' style lenses are?

"Because someone poured a lot of R&D into the Nikon D810 sensor (noticing a trend here?)"

Yes, I do notice a trend at DPR.

On article Fujifilm GFX 50S Review: Modern MF (898 comments in total)
In reply to:

Dragonrider: In comparing to the 5DSR, it is worth noting that the FF typically has at least a 1 stop, and often 2 stop lens advantage over MF, so when you get very far beyond base ISO and give the 5DSR a 1 stop exposure advantage, it looks pretty darn good. The big sensor wins at base ISO, but for more general purpose use, the 5DSR looks very good IQ wise and its AF is very fast and accurate. I don't think I will be trading mine in on a GFX.

A couple of the 645Z lenses are stabilized.

In reply to:

Angrymagpie: Seems like to go with the GFX50S, one has to compromise quite a bit on camera performance for a relatively small IQ gain.
Judging from the rapid advancement of the FF mirrorless cameras since the A7 came out, I can't wait to see what happens in a few years' time.
