Newer sensors worse results? (open letter)

the depth of field effects are significant, in my opinion. so what's going on there? perhaps out of focus areas strike the film plane more perpendicularly than in focus areas? i'm no optical engineer, so i can't explain. Isn't that the opposite of what he's saying? Marginal light rays being less per...

Newer sensors worse results? (open letter)

I think this can be true with the older lenses because it didn't so much matter if the light falls on the film under an angle because the sensitive cells where on top. but i find that my older lenses certainly had a markedly shallower depth of field at f/1.4 than at f/2. i'm talking of my old minolt...

K-7 startup is this normal?

Just got my K-7... On startup it makes this sound- churrk! Its not the sound of the sensor clean function... its a much higher pitched sound (which the camera does after this churrk sound) The K-7 I rented did not make this churrk sound. It doesn't look like I can do attachments... her...

K-7 startup is this normal?

The sensor clean on the K-7 sounds like a brief high pitched noise, not the brrrr-thunk! of previous Pentax DLSRs. You can no longer feel the vibration either. It's all supersonic now, don't you know. :D I think mine makes that noise on start up too. Now I'm going to go and check for sure.

My K7 does this (I have the snesor cleaning disabled at start-up). Don't know what it is though! Andy

K-7 startup is this normal?

Seen at the 'other place': All kidding aside, this is apparently normal. Pentax Europe GmbH addressed this concern in a FAQ media release: http://media.pentax.de/downloads/pho...0Antworten.pdf Translation: "When you turn the camera the camera makes a strange noise. A strange "noise and bee...

The K5 Experience

Er Has anyone noticed that when you tilt a K5 to the left or right there is a sort of 'sliding' sound???:shock: No. Just been trying it. It is probably the floating sensor though. I never use the computer terminals so I am not worried about the rubber door. At least not until it rots. But maybe i...

New Conundrum

I have another conundrum thread on the go in the lens Section, so then... I now have a K5 and a K7 (Haven't actually used the 5 yet!) Coming from Nikon I've had a hard time dealing with the Sensor in the k7 (Samsung?) Hellacious noise in shadows, I actually sent one off to Johnsons Photopia to hav...

New Conundrum

Yeah I'm thinking Kr as soon as they become available as a Body Only in the U.K. I think the Control Layout is Similar enough with obviously a few bits buried in Menu's as all the Manufacturers do! (Can't have all the toys in the Lower end stuff or they'd never sell any of it!) Battery commonality ...

New Conundrum

You mention 2nd body as you like to use 2 bodies at a time with primes, in which case, anything other than identical bodies, to me, is a waste of time. It's why we have 2x K-7s Therefore the ideal 2nd body to a K-5 is a K-5. A backup body is an entirely different proposition to a 2nd body thou...

New Conundrum

Unlocker, I would love 2 bodies but Cash is the problem! Can't afford to buy another K5 until I get my Sorry Arthritic broken backed asthmatic apology of a body back into a job! Sorry digressing :oops: Like I say my choice is keep the K7 that I have trouble liking (Sensor is the only deal here!) Or...

Pentax KR

Here's a link to the EPZ review ; http://www.ephotozine.com/article/Pentax-Kr-14989 One interesting result shows that the Infra Red blocking filter over this sensor may not be as strong as on previous Pentax DSLRs. Hmmm interesting :) A bit sad that ephotozine just reviewed the DA 18-250 while...

New firmware K-5 coming this month

There might also be some optimization involved most likely because they also improve the performance of the Codec for Win/mac but but no way optimization alone can account for 150% increase :shock: Though I imagine there will be a caviet with regards to the type of memory card you have. I've remo...

New firmware K-5 coming this month

I wonder if the update is processor base because they use the same processor in the K7 as in the K5 right so they should also be able to do it with the k7 maybe... i wonder what numbers you would get then. Maybe the processor can keep up with 108MB/s meaning your SD-card would be the weakest link. ...

So how good is the K-5 sensor

Wow! :shock: EDIT: Interesting to compare against the 5Dmk2 as well ;) EDIT: Also interesting to see the actual measured ISO of other manufacturers! Pentax seem to be closer to the actual rating ;) :D Matt

See you knew it was worth getting one. A new ironing board is a small price to pay :D For DXO to have results like that it MUST be good :lol::lol:.

Is it the same sensor that Nikon are using in their new D7000? I know they use Sony sensors and seems bit of a coincidence to me
