Mike I don't have anything yet and I broke up with my girl so no exciting pictures from me
Although I might go to the club, lots of ropes, girls in harnesses and boys too hanging in the air, how does that sound?

The more I think about this the more I wonder if the size of the mount has anything to do with it.
Surely it is all dependent on the size of the front element and the amount of light getting into the lens? And the mount has no effect?
Well just measured it and it's 45mm if you don't believe me measure it yourself The more I think about this the more I wonder if the size of the mount has anything to do with it.

It depends on the size mount and the register distance (not so really on the front element besides with lenses of other design but you still have the limitation how big the rear element can be).
When you focal length is smaller then you register distance the lens must travel inside the mirror housing, that isn't a big problem but you can only go so far before hitting the mirror. actually most fast primes travel slightly into the housing and have a smaller rear element then you would think.
So if you want to have wide angle lenses you need to use different lens designs, they actually used a reversed telephoto design for it.

A telephoto lens works by having the outermost (i.e. light gathering) element of a much shorter focal length than the equivalent long-focus lens and then incorporating a second set of elements close to the film or sensor plane that extend the cone of light so that it appears to have come from a lens of much greater focal length.
That's why the front element is important with these designs but the rear elements are still subjected to the physical limitations of the lens mount, does that make sense?A telephoto lens works by having the outermost (i.e. light gathering) element of a much shorter focal length than the equivalent long-focus lens and then incorporating a second set of elements close to the film or sensor plane that extend the cone of light so that it appears to have come from a lens of much greater focal length.
About the diameter, I believe the size mount for the Canon is 52mm so it's no wonder they could make an f/1 lens but they even hardly sold any of them because of the price.
Making a f/1 lens for the K-mount would be a lot more challenging and therefore going to cost more then the Canon 50mm f/1
I just searched for the Nikon lens but the fastest they had was an f/1.2 so would be interesting to see where you found the Nikon f/1 lens.

Thank you all for the kind words, they will push me on to do better next time
Gareth, Irish you say, I've never been there but they look like a "gezellige" (cosy) people.
many people do like the highlights and I haven't had any comments that where against them so I might just live with it, sometimes you must just stop working on it.
And today is my birthday so a good excuse to do nothing

Great image in either colour, Stefan. Though I think I prefer the gold.
Re. the highlights - I hesitate to give people who are clearly much more skilled in pp-ing than me advice, but were you using ACR for the RAW conversion and if so did you push the Recovery to its limit?
Super idea, didn't thought about that one, it would mean however to restart it all over again Great image in either colour, Stefan. Though I think I prefer the gold.

Make it into an action.
Simply make a logo or something else, let it upload that in a layer on top and set the Layer blending option to "screen" it will blend into the image or try out other blending modes to see what you like.
You can record what you do in an action and then when converting them to a lower size you can let the program preform the action automaticly.

Just out of interest, is there an UPPER limit for SD cards in these cameras !? Just checked my K10 manual and spec stops at 4GB !!
Could it be they are not equipped to handle above 4GB ??
4GB is another threshold point, as was 1GB some years ago !!
I use 4GB and have never tried above
SD = up to 2 GBJust out of interest, is there an UPPER limit for SD cards in these cameras !? Just checked my K10 manual and spec stops at 4GB !!

I use 4GB and have never tried above
SDHC = 4 GB up to 16 GB
SDXC = 32 GB up to 2 TB
I'm happily using a 8 GB in my K10D for 1.5 years now
I don't see why a 16 GB would be a problem, it use the same design as all the other SDHC cards.

I wonder how much of the market extra they should take then and how they must get a camera under the K-X?
2008, I know old numbers but you can see the models above the lowest entry level are more popular.
I would have thought the K200D's market penetration would've been higher, and I am surprised the K20D doesn't appear. It's not as if Pentax are invisible....If Pentax wait long enough they don't need one...

It went up with the K-M and ever further up with the K-X, I really don't know what market share they have now.

Yes my uncle has the K-X and I the K10D so I can compare and there are comparisons of the K-7 and the K-X sensor and the conclusion was that the K-7 showed less artefact at lower ISO then the K-X.Anvh wrote:

Not at low ISO, even my K10D preforms better there then the K-X On the other hand, with apologies to K7 owners it is an open secret that its sensor is inferior to that in the Kx.
They placed the base ISO of the K-X at around ISO 400 making more effective at higher ISO but if you go lower then you also need to give in on quality.
And it was already a know that the K10D was better at low ISO then the K20D making it automaticly better at low ISO then the K-7 and the K-X

Therefore, the K-x sensor outperforms the K-7 in low light situations whereas the K-7 outperforms the K-x in good light. This is further confirmed by the better resolution and more artifact-free images from the K-7.

Tony that sounds perfect, of course if a friend want to shoot it I'm more then happy to say yes but to see some here so stretch out with the idea of shooting a wedding I wander if i'm doing him a favor to say no instead Hear hear - spent most of my working life in the kitchen serving the wedding breakfast and if some of the £2k cakes were anything to go by I`m glad we got married with just two witnesses and afternoon tea ( 40 years ago this April ) - we don`t need the photos - we remind each other !

Thank you Peter.
Never thought so many would like so have processed photo.
