Interview with Hiroshi Onoda, manager of Pentax Europe.
As regards the original topic, I agree that Pentax are highly unlikely to bring out a full frame camera for the simple and already mentioned reason that this would be incompatible with the lens lineup. However, a happy compromise may exist; the Canon 5D MK IV uses a 1.3x crop factor sensor, and...

Interview with Hiroshi Onoda, manager of Pentax Europe.
I don't understand this argument at all. How can anyone can question the benefit of usable higher ISO? Even if it is only a one or two stop advantage, that's still a big deal. Because a useable higher ISO inevitably entails the use of a CMOS sensor and a higher base ISO (200-400) - this is undoubtab...

Interview with Hiroshi Onoda, manager of Pentax Europe.
...but I must say that I don't see much evidence of K10D shots being better quality at low ISO than K20D shots. I've never had a K10D so I may well be mistaken. :) I own a K10D and I've had extensive access to a GX20 and I'd say that at ISO200 they are comparable (with the GX20 resolving more detail...

Question on K7 autofocus speed, etc
But the motor isn't everything though, it's also the AF sensor and the software behind it. Wasn't it you Amin who tried a super fast K7 demo at SRS? Also Pentax is one of the few, maybe the only one that have lenses with SDM and screw-drive focus, many people forget about the complexity that's i...

which camera k20 ,kx,k7?
This question reads as though it should end with "Discuss" :!: There is far too much to say to compare the K200D, K20D, K-x and K-7: all very different beasts. I suggest you read up on the various reviews available online. The more specific question about low light in the K-x is perhaps easier ...

Is the latest kid on the block EVIL?
[quote:3496ace15f="ISO"]Sorry:oops: Don't be, I was actually hoping for some talk about this, it's most likely the future after all or don't you think so?

Is the latest kid on the block EVIL?
The brightness of the scene is raised when the light falls, seems duller in bright light Agreed with regard lightness of the scene in low light but this is borne out in the captured image too (not what your eye sees but what the sensor is capturing). So to my mind this is another advantage of the ...

Is the latest kid on the block EVIL?
The benefit of an EVF for me is that if the camera is set to monochrome I can compose the picture in monochrome. Likewise if the camera does IR I can compose the IR image rather than guess what it will look like. Unfortunately the camera I've got with an EVF is old now, but it did take many of t...

Returning to the world of Wide Angle
I was fully prepared for softish corners with the Sigma, but I'm surprised it was an issue on an aps-c sized sensor.

My first wedding shoot!
Unlike the human eye the camera sensor gets very confused when confronted with black (suit) and white (brides dress) let alone the added snow. The old way of taking the exposure from a grey card and setting the exposure manually works, also taking a reading in front of the subject with a light meter...

I need my 12-24mm to be 12-24. If you are ever able to buy a Pentax FF body, which I seriously doubt you will, prepare to be disappointed when you fit your 12-24mm to it. It's a DA series lens who's image circle suits the APS-C sensor size. It will vignette terribly at the wide end of its focal r...

Sigma has an 8mm lens which is 'comparable' to a 12mm lens. The 10-20mm is 'equivalent' a 15mm rectilinear lens and no such thing exists for FF at this point. You want a long zoom? Be prepared to have it weigh a hell of a lot more on FF than an APS-C equivalent. I've never understood why peop...

Peter I believe the problem was there aren't lenses wide enough on APS-C. Sigma now has the 8-16mm so on the wide that would be 14mm EAOV on 135formatt, the widest you seems to be able to get on 135formatt is 12mm so the question is. Are those 2mm worth to switch system for? The 645D also has a ...

There will always be new cameras coming out, but it'll soon reach the point where they are way beyond what anyone actually needs. I would much rather see Pentax investing in new technology regarding sensor design than going full-frame. The next generation of sensors should be more than adequate ...

There were very few lenses wider than 15mm until APS-C digital came along. Canon's widest 135 format lens is 14mm, which is a lot less wide than Sigma's 8-16mm, which is available in Pentax K mount. 8mm on APS-C is the equivellant of 14mm on 135format. :wink: As for lens speed, the depth of fiel...

I have a feeling in my bones that a Pentax FF will not be too long a wait! They are all ready here, I mean the sensor used in the k7 for example is fullframe APS-C film size or not? :| :mrgreen:

the vignette thing - I vignette most of my images slightly anyway, wether it be digital or film, i I have about 10 different vignette actions saved in photoshop, and you can correct for a vignette to a certain degree with a raw processor, so i am sure i could sort out the vignette of my 12-24 for in...

There is also the possibility that, if Pentax ever do a full-frame DSLR, they will do it in the way that Nikon did. In other words, DA lenses will still mount on the MZ-D (*), and for those that don't cover full frame (the DA70 does apparently) the sensor will automatically go into 'crop mode' so th...

Full-frame Pentax? I hope not!
Reading some comments on here and on other forums, I can't help wondering why so many people want to see a full-frame Pentax. Personally, I think if Pentax were to produce one it would be a step backwards. I think that new sensor technology will eventually make full-frame cameras obsolete. At th...
