Is Ricoh Pentax's last chance?
I'm not sure what you mean by 'All 35mm'... aren't they just quoting equivalent 35mm focal length - a standard practise really? Another thing is that those aren't lenses they are 'lensors'... all that additional cost and R&D of including a paired sensor in a sealed unit. Hopefully the introduc...

Is Ricoh Pentax's last chance?
It's basically a tweaked Kr, the sensor is the same, so you're not actually that wide of the mark. Sensor production may now be focussing on 16MP+ sensors, certainly 16MP is becoming 'the norm' for low-mid range cameras, which may be why the Kr has been discontinued. Alhough perhaps there's been a h...

DP 2011 Mirrorless Round Up
Tiny film/sensor formats have always got some stick. Remember the James Bond like Minox or of course Pentaxes or anyone elses futile attempts to make 110 work however nice the camera itself. I recall Kodak saying it was a revolutionary new film. Now we have sad news about Kodak failing having de...

DP 2011 Mirrorless Round Up
I think the Q ticks a lot of boxes in terms of it's features and 'pocketable' factor, and if I owned one, I'm sure I'd find it a lot of fun to use, and enjoy every picture taking moment. However, I have bought a 'mirrorless' camera, but it wasn't the Q. It is just far too over-priced for what is e...

Full Frame - Here we go again
Why the rant? Because if you think Pentax shoild bring out a full frame sensor you have to go on Facebook.

Why the rant? Because if you think Pentax shoild bring out a full frame sensor you have to go on Facebook. I completely agree, why should you have to join facebook just to vote, in fact why do you even need to have an internet connection and an online prescence? Pentax should have done a worldwi...

Full Frame - Here we go again
Looks like it came out of the Pentax museum to me and why have it pictured with an *istD? The screen on the back looks very small and not up to the resolution of the current one on the K-5. My theory is that these are photographs of an earlier attempt that never made it. Yep it's in the Asahi ...

Best selling cameras of 2011 in Japan
No one has suggested that Nikon drop FF cameras such as the D700, although it is 3.5 years old and a replacement doesn't seem to be a priority :wink: FF models traditionally seem to get refreshed less often, compared to the APSC models... there'll always be people who value a larger sensor with more...

Fringing - CCD or lens technique?
Complex issues, but the fringing is a combination of lens and sensor effects. Changing lenses will change the severity of the fault, and sometimes it can be virtually eliminated. I wouldn't worry too much about differences between CCD and CMOS sensors - in any event later CMOS cameras produce bet...

Fringing - CCD or lens technique?
I have found similarly that the plastic 35mm is a great lens, but I have also found that you can get purple fringing with high contrast areas. It is a lens issue I think rather than a sensor one. The junction between the edge of the rocks and the light sea behind is just such a high contrast area wi...

Fringing - CCD or lens technique?
I think you were referring to me Greg regarding CCD and CMOS! I can see a very distinct difference between pics taken with a CCD (K-m) and CMOS (K-x) sensor. Which is best depends on subjective opinion and the type of photo being taken. To my eyes, the CCD sensor is lovely for landscapes and give...

Fringing - CCD or lens technique?
Very interesting technical comparison between CCD and CMOS which seems to imply that getting high quality images from CMOS is more difficult than with CCD. To my eyes, in Pentax cameras the CCD images are slightly superior, assuming that ISO is kept at a reasonable level. For high ISO the CMOS ima...

K-5 discontinued?
Bet they will replace it now I have bought one! That said the replacement will be about £1200 for a good while. Well if it follows the pattern it will be due 18 months after the K-5, I'll put a bet on a new body design: K10D then K20D new sensor, more MP, some more features/fixes, same body. K...

K-5 discontinued?
Right then, I will now set the record straight regarding the K5 replacement. What I am about to relate is really pukka information. My source is my neighbour, who's cat is called Banzai and once rubbed itself against a Japanese tourist and then started purring. Nobody can deny that this is an uni...

K-5 discontinued?
expect a k5 with a new sensor, dual core processor capable of higher burst rates, 4k video, and faster af.

K-5 discontinued?
expect a k5 with a new sensor, dual core processor capable of higher burst rates, 4k video, and faster af. That is the exact recipe they should follow- an incremental improvement on an already very competent product. I would certainly be interested if I were in the market for a 2nd body (the K5 I ha...

K-5 discontinued?
TLR's didn't have a pentaprism :shock: As long as the rays from the lens to the eyepiece are bent by optical means and you see and record through one lens I would think it's an SLR?..... even when the lens to sensor passes through the first mirror.

K-5 discontinued?
But John, there is no mirror "system" in the new Sony “SLT” cameras such as the A77, A65 and before that the A55. The single non-mirror mirror present directs light solely to the autofocus subsystem. Everything projected in the EVF comes from light passing through to the sensor and as such these...

Used Price Advice
I am sure you will be very happy with it. If it is only 8 months old there should be some residual warranty (normally one year or two from a Pentax Pro dealer from new.) I had the use of a K-r last year while my K-5 was having its sensor stain problem sorted and I really liked the compact size an...
