It's quite likely that the lower resolution image will have less noise and might actually produce a preferable result. Images from a K100D don't always look worse than those from a K-5 despite the lesser resolution.

John K

How's using a different sensor going to change the focal length of a lens? That's nonsense.

John K

What would you like this new mount to offer that the K mount doesn't have? Should they force the angle of light to be too close to the sensor and I could foresee all sorts of aberrations being introduced.

If you sell them you won't need to bother insuring them! What you can get selling them and insuring them at replacement value might be quite different. Insurance value might be cost new - check SRS prices or have your purchase receipts to hand, second hand prices would be what you can get which depends on all manner of factors, mainly what someone is willing to pay. A trawl of eBay (check sold prices: not what some are hoping for!) and the site here should give some idea of current going rates but even then it depends on condition and to some extent location. (Sending a bulky package half way round the world can be expensive and off-putting.)

There are compatible wireless remote controls available that cover that range, eg: http://www.firstcall-photographic.co.uk/products/3503/hahnel-giga-t-pro-wireless...

Colour balance looks OK to me. My thought is perhaps a little over-sharpened but otherwise fine.

John K

I see. I've had lots like that too! As you say, someone might like to try and fix it for the cost of a stamp.

John K

If you've only just got it, why not send it back to the seller for a refund?

A quick reminder that this competition ends at midnight tonight (UK time.)
