lovely shot Liam, looks like you were out earlier than I was.

I love the way fresh snow makes things look, gonna have to take a holiday somewhere where it happens a lot I think, just don't get enough chances to shoot it in this country.

everyone I have showed these to has commented on the bikes, I'm glad it's so popular, it was one of those "that would make a good photo" moments which actually worked out.

I haven't tried a B&W conversion yet, might give it a go later on

To put the cat amongst the proverbial pigeons, the only lens I have bought which had any problems on delivery was a 31mm limited!
well I suppose that just goes to show that some lenses from any brand must be made on Friday afternoon

I think as with many things the people who have no trouble tend to be less vocal than those who do. It's probably a case of (and don't quote me on these stats I am litterally pulling them from thin air) 90% of all sigma lenses are fine compared to 95% of Pentax

Mongoose, I think you need to quantify how many is 'a lot' in your comment on people who received friday afternoon models'.

I am struggling to find a negative comment on it so I think it is far from the 50/50 your wording would suggest.

There was a magazine article a few months back where they went into the sigma warehouse and picked out several copies of the same lens at random (the 105 macro I think) and ran comparison tests because of this reported issue of poor standards, the results were very good.
possibly my wording is a little unfair, I should stress that I have not actually used the sigma 10-20 myself. My comment is based on the comments of people on Phototakers.com. Since I have a reputation for being able to find 1 dud piece of equipment in a pile of working ones I am possibly more paranoid about quality control issues than most people.

I also get the impression that the perceived QC issues may (I stress may) be the result of differing opinions on what makes a good lens. The Sigma is said to have more barrel distortion than the Tokina 12-24 (and by extension the Pentax, which has the same optical design)

edit, I found a thread from a while back on Phototakers discussing the relative merits of the Sigma 10-20 and Tokina 12-24 http://www.phototakers.com/forum/ftopic46989.html?highlight=angle

the only thing with the Sigma is I hear the sample variation is quite bad. There are a lot of people who are REALLY pleased with their sigma 10-20, and a lot of people who got Friday afternoon models.

If I was looking at that sigma I'd want to try the exact lens I was buying on my camera first.

To be honest multi-exposure has to be the least used feature I have ever had on a camera and even more so since digital (just combine them in photoshop and have a better chance of getting the placement right!), but I think this was the original question.
I agree completely. Being able to do it on the camera is kinda cool, but the result of doing it in photoshop is likely to be better.

I think a better option would be an auto bracketing facility where the camera takes ONE image and then writes a further two to the users prefered settings. this would be ideal for things that are likely to move during exposure like birds.

Currently we have a typical scenario of;
frame 1, turns out OK but not brill'
frame 2, not quite right
frame 3, exposure right on the nail, only the thing flew away so all you have is a perfectly exposed blur!

OK OK, I know there is a lot of leeway with RAW and it would probably only be of use with jpeg but whats the point of having auto-bracketing if your going to push or pull the image later

PS; am I allowed to use the terms push and pull for digital?
But auto bracketing changes the physical exposure settings, you have to take multiple shots otherwise all you are doing is developing the RAW file +- 1 stop. Since the K10D RAW files are typically ~10 megs and its JPGs around 3 you might as well have just shot RAW in the first place.

If you are talking about WB, filters etc, it is my understanding that the K10D does this already. It's not something that interests me, so I don't use it.


No matter what advances Pentax and friends make to in camera editing, it will never be able to stand up to doing the same thing later in Photoshop. I would much rather pay Pentax £600 for a really 1st rate camera with no editing capabilities than £600 for a second rate camera with the ability to run Photoshop Elements.

Wouldn't it be easier just to get a microscope?? Say a scanning-electron one

you mean sorta like this

lol kidding, that isn't a penny at all. It's from my MSci project last year. It's long chain hyrodocarbon molecules on a graphite surface. Scanning Tunneling Microscopes are fun

Dan, I salute you, don't thin I can better that without actually resorting to a microscope (though I did see an Oly microscope camera setup on ebay earlier....)

I tried reversing the 18-55 at 18 on the 80-320 with a 2x converter but the viewfinder is so dark you can't see anything.
