I was wondering about that too. (I meant to ask that as well when I asked about the type of remote.) Thanks for advising a cheap IR remote coped OK.

You're really lucky to have such a diverse hunting ground close to you to take these and the bird photos.

Perhaps it would be better if their 'find a dealer' page said that!

For Scarborough:

PC World }_ It's the same shop! - K-r twin lens kit in stock
Curry's.....}
Comet - no Pentax stocked
Jessops - no Pentax stocked
Argos - Out of stock in the 10 nearest stores
Currys - a branch 20 miles away - K-r twin lens kit in stock

I note their site is using the American term 'Zipcode' rather than our UK 'Postcode,' yet it's a .co.uk site with their server in Germany.

Why don't you try and get a bit more on eBay. It's a very specialized item and would do better in front of a wider audience. If you reckon they go for £50, then try for £35-£40 - maybe you'd get more.

As it happens, I was given one a year or so ago and will no doubt put it on eBay sometime. If I could get £50 for it I'd be pretty thrilled!

Even if you gave some people a copy of the actual legislation to show them they wouldn't believe it.

Nothing really untoward happened here. I wonder what they'd have done if a local TV news crew turned up to film them?

Well as already advised it's 52mm for the kit lenses (18-55 and 50-200.) If it's a different lens, which one? Most of the 'limited' lenses use a 49mm filter while other popular lenses need filters as large as 77mm or more.
If it helps, there are 'stepping rings' which allow one to use, say, a 52mm filter on a lens that needs a 49mm one or even the other way around (in which case watch out for the filter causing 'vignetting.')

Back in the days of the M and A series of lenses, many were 49mm. Perhaps who advised you was thinking back?!

This site shows details of most Pentax lenses link which includes the size of filters they take.

John

Recent FF cameras, alas not from Pentax, usually have the facility to automatically crop images from APS-C lenses to avoid that. Obviously one wouldn't get the full value of the FF sensor but the lenses will still do exactly what they do now. It seems not all ASPS-C lenses do vignette though (according to those examples that have been shown here.)
So there is a stop gap until replacement glass is obtained if and when the time comes.

John

Probably best to ask the seller if he has that facility or is willing to do it.

HMRC has a web page here: hmrc

Well it was something I'd read while considering purchasing a lens - it was in a review. I've looked, but cannot find the exact article presently but there is a similar reference to it here: link

If I can find the original reference I saw where quick shift was mentioned I'll come back with that too but its a bit like trying to find a needle in a haystack, given all the links that come up when Googling SDM.

Re a supersonic lens, the inference is that it is quick, quiet and smooth etc. If it isn't it's cunning marketing hype 'cause it sounds as if it should be.
However the 17-70 is quick, quiet and smooth, so given that it is working properly that lens, at least, lives up to that reputation. But limited prime quality (with its optics), it isn't (perhaps they are not all equal in this of course as I've only seen my sample of one.) But trying to focus that lens manually is pretty tricky as the focus throw is completed in quite a tiny arc, no doubt giving it its fast focussing ability.

There are some lenses that have both SDM and screw drive. Surely they could be used to give a comparison as to the relative speeds of both systems, as the only variable is the focus system (if it can be done?)

This was one of my first shots to test what was then a recently acquired 150-500 last September (equally boring subject!):

ISO 400

I usually take a similar shot with my new lenses to compare them. It seems quite a bit sharper than the one you have, but I've stopped it down a little and it was a brighter day so may not prove anything.

My suggestion is to find a similar flat subject on a brighter day and try again before dismissing it.
