The New Pentax Q

    As a long-term Velvia user, I just can't get excited about dynamic range - every digital camera has more than I was used to.

    Very good!

    Looking at the spec, the size is almost exactly in line with my Rollei B35. I'd certainly have preferred a bigger sensor but to be honest I think this will surprise people with its IQ. Not blow them away, but it'll hold its own I reckon. Holgas have been going for about 30 years now, so there's a clear market for 'different' cameras.

    The new Pen 'mini' may change my mind about what to expect in a small package, but we'll have to see how tiny they can get it whilst still being functional. The Pentax seems to work in terms of controls and spec at least.

    I think it is a test model and they will probably upgrade it (Q2) say 6 months for now with a bigger sensor.

    There are plenty of slightly larger sensors out there.

    It's a toe in the waters of CSC I suspect.

    Or it's a compact with interchangeable lenses instead of SLR without the good bits.

    I'm looking forward to seeing it. Doubt I'll shell out for one but as someone that likes photographing small things the small sensor may not be a bad thing.....a 1:1 macro lens could fill the frame with jumping spiders when on my DSLR I might need around 3:1 for example. Being able to shoot at 1:1 instead of 3:1 would give about 5 times more DoF.

    For macro work the CSCs out there have nothing going for them alongside my 7D....with a suitable lens, this one might have.

    Yes, Andrew. I think the main advantage of the small sensor in the Q is that it gives you more DoF when that's what you want. Although it probably wont be as good for available darkness black cat in the coal cellar at midnight shots as a FF D3s, it should give acceptable results in reasonable light.

    All it really needs now are a few specialised lenses (e.g. macro, landscape wide) to make best use of its strengths. Remember that with the small sensor, you don't stop down much because diffraction starts hitting you around f/4 - f/5, but you still come out ahead of APS-C at f/11.

    You might be surprised how well a compact with a wee sensor can do. These were taken in a very dark pub(much of it was lit by candles).....

    The 2nd one was taken with a (16.2MP!) compact held above my head in the HDR scene mode...the only controls are zoom and white balance, which I've never moved from auto. I thought it did remarkably well for a toy camera:)

    Agree with your other points like acceptable in good light as that is what my compact is primarily for - choclate box landscapes on chocolate box days. As for diffraction....you need to account for magnification....for example at 3:1 f/11 will be a lot fuzzier than f/11 at 1:1 due to diffraction. At 5:1 I'm using a f/2.8 lens at around f/4 to find the sweet spot. (being able to shoot at lower magnifictions evens the playing field a bit with regards to pixel density and diffraction on smaller sensors)

    If they did replace it so soon they'd p*ss everyone who bought it right off!

    (Mind you, I seem to recall a controversy many years ago about the Pentax ESII SLR being released too soon after the ES, so who knows?)

    Looks they have got form then. :)

    ESII was only a year later from the ES.

    I think that's a staggeringly unlikely, given the new lens mount designed for this format.

    I'd tend to agree, but as we don't yet know the image circle any of the lenses produce, stranger things have happened... The sad thing is no matter how good the image quality, many will discount it for having a small sensor. I think it's quite funny how things go around in circles, back to when 'full frame' 35mm was the new small and derided format.

    With a removable lens and a tiny 1/2.3″ sensor any dust will be more than a nuisance it'll be a disaster. I hope the anti-dust measures are 100%. :confused:

    WHS. Good point.

    From Pentax:
    The PENTAX Q’s DRII (Dust Removal II) mechanism effectively prevents annoying dust spots from spoiling captured images, even after the user changes lenses out in the open. Like PENTAX’s K-5 and 645D digital SLR cameras, it incorporates highly effective supersonic vibration mechanism, which vibrates image sensor at high speed to shake the dust off its surface.

    For the buyer's sake let's hope they're right. What's a dust bunnie on my FF would wipe out a goodly chunk of that wee sensor. :)

    What about sticky pollen grains? Ooooh.:)

    I do with them well with this though I will not be buying one.

    Rumour has it that the first firmware update will have an option to disable the DR. It'll be listed under the creative filters... ;)

    I'm really intrigued by this new system, but part of me says a Pen Mini with 14, 20 and 45 lenses is the saner option.

    If the sensor is small enough it wouldn't be that hard for a shutter to close like an aperture between the end of the lens and the sensor when the lens is removed, would it? there would still be a bit of dust but not much i wager. Perhaps a feature for Q2.

    In the Pentax Auto 110 the shutter was also the aperture, a quite clever arrangement.

    There's plenty of innovation comes out of Pentax, which I guess is one reason they are being snapped up by Ricoh.

    steady girls; I was told quite sharply about how to use a smiley early in my (admittedly new) life on here, as the hastily written word can be taken the wrong way otherwise, there being no spoken word tone inflexions, and one of my quips fell quite flat in a similar way. So I suppose we have a sort of web etiquette to adhere to, but at the same time the original offending note was actually pretty obviously sardonic I think, so let's not hag the poster! Anyway, :eek:

    PS as I am higgorant what is the new mentioned camera like?
