I think part of the problem is that TTL sensors didn't meter off the sensor correctly as it doesn't behave like film and this was the easiest option.

LOL, that is funny. I am waiting for some new sets to arrive so I have spares for my flashes. I got them from a seller on amazon and the only thing that worries me is the silly number of counterfeits. Maybe should have bought from SRS?

I have used my 50-135 in torrential rain on the K10D, quite confident with the sealing on that lens.
The long end look a little soft, mostly low contrast, not lack of sharpness.
It is an amazing lens, yet I still use it less than the 16-50

Yep!
No pre-flash > No flash metering > Wrong exposure
Sadly not like TTL where the flash was metered by light bouncing off the film so only needed a single flash.

Yeah, I had thought that too. Then I thought BOOM!
Wireless triggers may also be affected by the voltage. You need to check the specs.
Just looking at the Cactus V5:
Together with the provided PC Sync and 3.5mm cables and 6.25mm plug adapter, photographers may use Cactus V5 with any** portable flash and studio strobe with trigger voltage under 300V or under.
Looks like hot-shoe use might fry the transceiver.

I know its not a prime but the 60-250mm meets all those requirements imo.a longer telephoto da-limited.

If you want compact the DA*200 is very good and fairly small and light or the DA*50-135 which is compact and wonderful!

So we say that Pentax have had an input to some of the sensor design and along with their software have produced excellent IQ. The D7000 and K5 seem very close in IQ and low noise to assume that they are common manufacture to two different standards though?
Do you have any links to Pentax input to the sensor manufacturing specs?
If true, then that's an extra strand in the DNA.

It is very interesting the way electronics are put together.

Just with the K10D as an example:
Processor: Fujitsu Milbeaut M-4 MB91680
Analogue to Digital converter: NuCore NDX-2240
Sensor: Sony 10MP CCD
LCD: (Likely to be Samsung)
RAM: Samsung DDR2
Shutter, and other components could come from anywhere.

Sonly 6MP CCD in the D50, D40, *ist D, *ist D2, *ist DS, K100 and K100D Super
Sony 10MP CCD sensor in the D80, D200, K10D and the K200
Sony 16MP CMOS in the D7000 and K-5
The newer FX sensors may still be built at a Sony plant as there are few mature image sensor plants. Yes you can convert any wafer manufacture plant but other than Samsung not many have done this. I don't know of Nikon having their own plants so it would have to be build my someone with big CCD/CMOS manufacturing capabilities like Kodak, Sony, Samsung and a few others.

The K10's sensor narrowly beats the K20D and K-7 sensors for DR so I wouldn't really be tempted by the K-7.
I really like the amount of detail that the K10D captures even though high sensitivity performance is poor. The Samsung CMOS is only better because of the higher resolution masking more noise. For prints I find the K10D is still very good.
I would definitely want to move up to a K-5 but if I had a K-X and a K10D rather than two K10Ds I'd have a hard time choosing which to part with.
The build of the K10D and dual controls is very good to have, although if I used TV or AV mode then you only need one wheel (except for exposure compensation but I use a button press for that anyway on the K10Ds)
I guess what I am saying is sell the K10D and replace it with a K-5. Keep the K-x as a second body, it will work out better than the K10D in the long run.

Not sure where you got your Nikon sensor information but Pentax have input into Sony's sensor design as well. In fact Pentax do better with the same Sony sensors than Nikon does. It has been the same each time they have used the same sensor.DoctorJeff wrote:

Did Pentax ALWAYS make their own shutter units back in the days of 35mm rollfilm?

Yet Sony and Canon have their sensor, their camera and their lenses, Nikon have their bodies and lenses and their "design" sensors.K10D wrote:

Follow that argument and you must also agree that Boeing never built an aircraft - since they always used someone else's engines. In all cases above we have a third party sensor. ... ...
