Just messing about with my K-5 @ ISO 12800, Sigma 70-300 f/4-5.6 APO (@250mm) with a 2x teleconverter (Teleplus MC7 KAX) handheld at 1/15 sec. (fairly well braced).

The EXIF indicates 600mm as this is what I set (the converter is only a 6 contact KA). I've done nothing to the raw image apart from reduce the vertical size to 800 pixels.

Hi All,

Having found a problem with my 35mm lens, I've decided to withdraw this from sale until I can check it out properly.

Thanks to those that have looked.

John.

Hi Algi,

Thanks for the additional info. I'm not quite sure what I'm going to do with it at the moment.

My opinion: To make a thorough comparison between 12/14 bits you'd have to consider the whole 'end to end' process from real world image through to the final output (whether that's a print, projection or displayed on a screen). The raw output is just a small part of that process and you could easily loose the equivalence of those two bits before the light hits the sensor or after the data has left the camera. Only rigorous 'laboratory' comparisons are likely to show significant differences and most of these would get lost in 'real world' images.

As for the K-5/K-30 discussion, for me the choice is down to budget, availability, usability and what your crystal ball tells you about the future.

Hi Algi,

That's the one thing I hadn't checked, having done so I've discovered it is sticky (are you telepathic or is it a common problem?). I have used it on both film and digital without problems, but I'm not happy with it's condition and will have to withdraw it from sale.

Algi: Thanks for asking the question, I wouldn't have wanted to disappoint a prospective purchaser.

Thanks for those who looked at it.

John.
