ogl · 09-07-2010, 10:17 PM

It will be funny if K-r and K-5 have new Samsung sensors.

Wait, I thought that K-x was the camera with many colors.

Just kidding. I have been practicing taking quotes out of context. It is fun.

But I wholeheartely agree. You are one of the very few who holds that view here, and thank you for sharing. However, there will then be dumb asses who will be asking if you can really distinguish pictures taken by these two cameras on uncalibrated monitors. Those mortals . . . .

Another thing i do not understand is the lens line up. Isn't Hoya a premier glass and optics designer.
Pentax just isn't giving me that warm and fuzzy feeling. I am kinda worried.

Too bad for them. Just bad business.

Sure, Gary - you and some others would like the decent K-x sensor in the K-7 successor, but as has been discussed, there needs to be more pushing of the envelope if Pentax's flagship model is to compare and compete with the rival companies, making new buyers go for Pentax over the other brands for good reasons. The sensor is the heart of the camera, and has to perform. 12Mp is simply not the way forward for Pentax in the K-5. I'm certainly not advocating a pixel competition, but with 14Mp being offered in the last 2 flagship models, going backward in the next model is a definite backward move. I'd personally be disappointed - and it wouldn't be right to fit it in the K-r either...

Now the K-7 was definitely no failure either, regardless of the sentiment expressed here by a few - it actually put Pentax on the map internationally. People's heads were turning towards the K-7, then when the K-x came out, it too became a hit internationally. Things are looking up for Pentax, but yes, the momentum does need to build up for the success to continue, so I'm hopeful that in just over 24 hours this will indeed be the case...

Yeah, the bashed, crappy Samsung sensor... I really pray for updated Samsung sensor... with lower dark noise at ISO1600-3200. I even bought another GX20 body, you know...because of it's wonderful performance at low ISO. Look at this comparison at ISO100. I don't want to denoise photos made at ISO100

zackspeed · 09-08-2010, 02:03 AM

oh yes.......the samsung in the k-7 is one of the best for low iso,but nobody will know that.
and till 2000asa it´s no problem to work with the k-7,nobody will know this.
but samsung is history now...

rhermans · 09-08-2010, 02:20 AM

Please correct me if I'm wrong.

I'm still curious about the effects of the 1/3 light loss. If the camera acts like it is using an iso100 the sensor must be doing an extra effort to get there, what would mean that it is going at iso166.
So at 12.8K ISO it is really pushing the limit at 19.2K ISO what is simply stunning.
We won't know what the k5 will do, or even if it's the same sensor but I'm getting pretty interrested.

That's just the effects of noise

It would be extremely funny if we find a kodak or a fuji sensor inside.

The Fuji zealots would roll over in their graves!

I still have a soft spot for the S5 Pro btw.

alessandro63 · 09-08-2010, 02:46 AM

jokes apart, is it a different watch, or something I don't know is happening?
I mean the missing horizontal black line in the 9 hour spot in the Sony and Canon image. Abrupt ghosting removal???
