Pentax K7, Pentax 50mm, RAW, Silkypix.
Pentax K7, Sigma 30mm, RAW, Lightroom.
Pentax K7, Pentax 50mm, JPG.
Pentax K7, Sigma 30mm, JPG
In all cases above we have a third party sensor.
With the Pentax lens, we have a direct input from Pentax as to IQ.
Shooting RAW and assuming a “non-processed” file is then processed in Silkypix software we have an image with Pentax DNA only with the lens. (1)
With the Sigma lens there is nothing in the image attributed to Pentax with the exception of RAW data minimal processing. (0)
With the Pentax lens and JPG output we have the lens and the Pentax in camera software strands in the DNA. (2)
With the Sigma lens we have only the in camera software strand in the DNA. (1)
The 645D has two strands by default (lens and JPG processing) and should hold that as I don’t know of third party glass that fits the 645D.
NCS can boast three strands in some of their cameras.
My own opinion is that there is more to it than I have said above but I always like to look at what actually goes to make an image. Individual component parts can make or break an image. In general terms, a duff lens is the most that any of us will experience wrt IQ, assuming all else is done correctly, exposure etc.
Always worth stopping to give thought to what you actually mean when you say “I shoot with a Pentax”.
This is not a show stopper post; it’s intended to get the logic working.

Just comparing the discounts on the 60D/7D and the D7000 with the K5. Serious price reductions over similar periods in relation to the K5, which when you take the cashback offer into consideration is more expensive now than it was in November (maybe earlier)?
Can this be rationally explained?
Maybe down to great reviews.Just comparing the discounts on the 60D/7D and the D7000 with the K5. Serious price reductions over similar periods in relation to the K5, which when you take the cashback offer into consideration is more expensive now than it was in November (maybe earlier)?

Smaller sales numbers normally means higher price.
Plain profiteering by the importer.

I have the money ready to pay for the repair of my 16-50 SDM (self inflicted damage)but it seems like it's in use by Peter Pan in Never Never Land. Main Pentax agent in Oz (CR Kennedy) are a wee bit lacking in communications. Can't even find out if they have sent the lens to Japan.Mike-P wrote:

Still happy with the Sigma 17-50 OS but miss the 16-50 SDM. Is 1mm wider really worth it? ABSOLUTELY!

No, not one of those. It is just a combined plug/transformer that you use to charge the NiCAD packs for the LX motordrive.

OK. I made my own. The main thing was to keep the charge to 11mA as I remember that the cells are 110mA nicads. Input was 24vDC. I can send you the details as it's a simple arrangement to make. I ended up marking +ve & -ve on my power pack case as I used individual cables with small sleeve sockets to fit the power pack pins. Works fine and is reverse polarity protected. (If I was in UK, I'd make one up for you).No, not one of those. It is just a combined plug/transformer that you use to charge the NiCAD packs for the LX motordrive.

Well there ya go. A positive attitude! Good for you.I'm not really celebrating it, but it seems that I'm not qualified since I use a Samsung GX-10 (yeah I know). Regardless of the weather, I'm still going out and will be going around West London, around the Ealing area to check out some areas.
Over this side, we are attending a Moto Guzzi and Italian car meet at Mullberry on Swan. Weather is warm as Perth is mid way through a heat wave. Serious levels of UV and blue stuff above.

Some of you probably want to know how it compares to the competition (Pentax K-5, Sony Alpha 55, Canon 60D). In a word: similar. It's impossible to do apples-to-apples comparisons because there are plenty of things that get in the way of that. But in playing with raw files from each of the cameras with the same converter, what I wrote in the bullets just above tends to be fairly similar across the cameras. The Sony and Canon seem to "lose it" slightly faster than the Nikon and Pentax when you start pushing above ISO 800, but all produce a "usable" ISO 3200 result. The Pentax seems to hold color slightly longer than the Nikon, but it also clearly starts adding noise reduction (even in raw) at the highest ISO values, which means that edges look more anti-aliased. Realistically, if you're nitpicking noise between these four cameras, you're nitpicking. I would guess that if you need ISO 6400 in a DSLR, lenses are going to be a bigger determinant of your final results than the noise levels. That said, I don't like the look of the Pentax files above ISO 6400, or the look of the Sony or Canon files above ISO 3200. The D7000? I don't like the look of its files above ISO 12,800. But if you think about that for a moment, we're talking two stops maximum between all the contenders, and probably less (I doubt those of you reading this are nearly as picky as me). That's the difference between using a kit lens (f/4 on average) and a modestly fast prime (f/2). If you're not already maxing out a fast prime, well, you really shouldn't be pixel peeping noise. And like I just wrote, if you are using a fast prime, the lens you're using is going to determine your final results as much as the sensor's noise.
