Bump!

Samsung GX-20 and grip brand new in box(es) £500

I bought this just over a year ago as a backup but haven't so much as put a battery in it, so I thought it was about time to find it a new home. I've only taken it out of the box to take the photos below so it's in absolutely mint condition.

I'd prefer not to split for the moment, and anyway the grip only fits the GX-20, not the K20.

David put the 50-135 up on ebay a week or so ago BIN. Don't know if it sold.

You need to make sure you get one which, like the original, sits inside the throat of the mount. Many of the cheaper Chinese ones on ebay have a flange that sits between the body and the lens and prevents infinity focus.

From Warehouse Express's Twitter feed today:

Not sure atm what precise details I can give @korm87. But cameras, lenses & accessories are amongst the items. (we weren't the target btw)

I'm sure any self-respecting camera thief would turn his nose up at Pentax gear, but best keep an eye out just in case...

Thanks for an excellent and informative study labnut.

I'd be really interested to see the results for a longer focal length (but not quite interested enough to do the study myself!). My impression on the K10 is that SR is more efective for (relatively) long exposures and short focal lengths, and doesn't seem to be so effective at longer (300mm+) focal lengths. But I'd be happy to be proved wrong...

To be honest, if you're not getting the results you'd like with the Pentax-M 50mm f1.7 then it's not the lens that's at fault...

If you want to see if AF would help, then try using trap focus. Set your camera to AF-C and it'll only let you take a picture when it thinks the lens is in focus (this only works for manual lenses).

Yes, it's an extremely good lens. No, it isn't better than the DA* (it is a bit lighter though). The main optical advantage of the DA* is that it focuses down to 1.4m as opposed to 4m for the A*. Shouldn't think that makes much difference with planes though...

Oops! I meant a linear polariser and a circular polariser, not two CPLs.

Hi,

does anyone have any experience of "stacking" filters on the Sigma 17-70 and how many you can get away with before it starts vignetting at the wide end?

I'm wondering

a) whether you can get away with using a 72-77m step-up ring and 77mm filters.

b) whether you can get away with stacking two CPL filters to get a variable ND.
