Don't go for the Sigma. I have one and it is rubbish. The IQ is good when it works, but there is the issue "When it works"

Looks good though Excellent job there.

for film and scanners, I bought a lead lined fold away bag specifically for film a few years ago when I went to Egypt. It came up on the scanner as a big black rectangle, so they wanted to check it out. I opened it up and proved that it was film. The security said I didn't need it. But I wanted to be safe. And Indeed it was. So get one of those, I managed to get 15 rolls in it no problem. Just remember that you will be asked to open it, but the security will understand when the see what it is. Unlike Poland who put my olympus trip through the scanner 3 times and ruined the film, Gits!

Not often, however now that I have a couple of rolls of Kodachrome, I will be using it. One roll is in my Olympus trip and the other will go into my MZ-5n after I have filled the PanF that is already in it. I do have a time limit though, The kodachrome has to get to the USA before November. So. Here goes, use in the next couple of months and send off.

This is interesting, as although up to about 9 months ago, they had the Samsung version, the Pentax version has not be available new for a while.
Does this mean that Pentax are re-making it? or does it mean that Pentax have started shipping back to the UK again (like the FA 50mm)

Okay what lens are we talking about, well the 35mm F2!

Not cheap though, especially compared to the Sigma 30mm F1.4, but tempting nevertheless. Plus you can use it on film bodies unlike the Sigma.
With an EFOV of 52.5mm on the K10D and 54.25mm on the K20D/K7 it would be a great walkabout lens.


Hmmmmmmmmmmmmm

Hmmm interesting thread, with a lot of answers.
Like most people have said, it depends on what you want to shoot, the time of day, indoors and outdoors, flash or ambient light (ie fast apertures) etc etc.
I am lucky to have a large range of lenses to cover focal lengths from 10mm to 500mm, and if you include my cheap 2x up to 1000mm (only really good for moonshots....LOL)
I started buying cheap lenses which were not that fast but gave me an idea on what I wanted to shoot. When I started to find areas I was particularly interested in shooting I then endeavoured to buy better glass for that type of subject matter. For instance, portraits I started with a cheap 55-200 Sigma, but now I have the DA*50-135. To replace the kit lens, I now have the Sigma 24-70mm F2.8 EX, but it is heavy and does not go wide enough although again a great portrait lens especially in ambient light. So, to complement it, I also have the 16-45mm F4, which is light and on the camera most of the time when I am out and about.
It is however not that fast so, looking at getting the 16-50, which would be better for lower light and used when the weather is inclement.

So, ultimately is there a perfect range? probably not, as we will always want a lens which wil cover a different range/aspect/fast/low distortion/high disortion etc etc.

But at the moment, for me I suppose my "current" perfect range would be

Sigma 10-20mm (I have)
DA* 16-50
DA* 50-135 (I have)
DA* 60-250
DA* 300mm
DFA 100mm Macro WR
FA 50 F1.4 (I have)
FA 77mm Limited
FA 31mm Limited
DA 40mm Limited
DA 21mm Limited
DA 70mm Limited

These would cover all my photo needs, whether Landscapes, City, Portraits, Wildlife, Sport, Macro, Travel (the DA limiteds would come into their own here due to their small size and weight)

This of course would change, but in the meantime, I will use what I have and enjoy taking pictures with them.

I have polled saying popular as a 135mm is always a must have in the bag. I don't have this particular lens, but I do have 4, yes 4! 135mm lenses ranging from Carl Zeiss Jena 135mm F3.5 M42 to my fave, the Takumar F2.5, which is great and fun.

Why not just buy them for £10 and £20? You might find them fun and useful
If they are not what you want then bung them on fleabay.
For that price I would give them a go.

I have the Sigma 10-20mm and Love it. Not that I use it that often (I find the 16-45 more suitable for most situations). However when needed it comes into its own. As for QC issues with this lens, the only mounts I have heard problems with are Canon. Any other mounts, none at all.
This was taken on Sunday with the Sigma....

Very tempting, but with my 170-500 so I can stay well away.....
