The Pentax Q System - What do you think?

The new Pentax Q System was announced today - it's a compact 12mp Backlit CMOS 1/2.3inch sensor camera with interchangeable lenses - Pentax introduced 5 new Q-mount lenses for it... we had a look at how it compares both with the sensor size, and with the current competitors, both "serious compacts" and other mirrorless cameras:

It's come too late to the party. I know there will be those that will coo coo over it but..................tiny sensor. Cameras like The Canon G12 will offer similar if not better quality. Sorry to seem negative but it looks like Pentax have no answer to the Micro four thirds format or quality Bridge/Compacts like the Canon G12. Look at the recently leaked Olympus EPL micro camera for instance.

I think its a bit like the old pentax 110 slr - in hte same way that it gave you some of the functionality of a 35mm slr, the Q will give you some of the functionality of a compact system camera but not the image quality.

As the lens is the biggest part of both the Q cam and a compact system camera , you might as well go for a bigger sensor and get all the benefits that come with it.

Nice work Josh - very on the ball! Smile

So effectively a 5.8 crop camera.

Not sure the 4/3 sensor figures are quite right? Isn't it 18x13.5mm? See here .

Thanks, the sensor figures are originally from wikipedia: http://en.wikipedia.org/wiki/Image_sensor_format

Something I find odd, you hardly see compacts these days fitted with the larger 2/3" sensor, they seem to have been abandoned.

Surely if your going to build and interchangeable lens system using prosumer/digital compact size sensor you would want to fit the largest possible.

Sensors all vary in size a little from one model to the next CB.

At the moment it looks like it falls between two stools - the sensor size looks like offering inferior quality and no size advantage even to something like the Oly Xz1. Unless they can offer some seriously good lenses that offer a lot more than is currently available on fixed compacts this just looks like pitching too little and at an unattractive price.

Why do people assume the image quality will be inferior? The sensor is backlit which means it can collect more light per photosite, therefore greatly improving the signal-to-noise ratio. Time will tell, of course, but I'm not going to airily dismiss it on grounds of image quality without so much as seeing a test image....

Which gives the 4/3 sensor size as I have stated, i.e. 18 x13.5mm. 17.3 x13mm, as in the EPZ article, is actually the imaging area. I assume, but am happy to be corrected, that it is true of all sensors, including full-frame (36x24mm), that the imaging area is slightly less than the sensor's physical dimensions?

I think the Pentax Q will be a niche product - and nothing wrong with that. If it is significantly more pocketable than M4/3, it could do OK. Price will be critical, for what people might see as a compact with a lens that comes off. Wink

If they've somehow managed to miraculously alter the wavelength of light you might well be right.

Camera makers have come a long way in reducing read noise in the last few years, but shot noise is the ultimate stumbling block. Unless Pentax are a decade ahead of the big boys in enhancing sensitivity it's unlikely a sensor one tenth the area of full frame is going to be all that impressive. Virtually any camera can produce half decent images in good light.

I'm not sure it will be a niche product as such - looks like it be ideal for the traditional Leica rangefinder type market (street stuff etc). I will be looking for a serious compact type later this year - for candid work, holidays and for taking to the Olympics next year (don't really want to take full SLR system). So I will be looking at the review / prices of this with great interest.

This camera is squarely targeted at the mass consumer market, and consumers that love gadgets and those that are not interested in sensor size, noise ratios and so on.

Sure it will attract the odd photographer here and there as well, but I can`t see it offering a great deal to most seasoned photographers.

And its double the price of some Pen and Nex systems.
