This is the best comparison I could find link

Yeah Lightroom is a bit different then Photoshop.
Go to edit > preferences > external editing and you will find there in the tab additional external editors.
When you open the drop down menu of preset you will find Noise ninja there and you can adjust the file handling.
TIFF shouldn't be a problem most likely, don't use compression though.
Aint sure about the colour profile and bit rate, lightroom works in 16bit and pro-photospace so if you don't want to lose details, that's the one to try.

ps. I don't have noise ninja but this the way most plug-ins work in lightroom so hopefully it's the same.

Have only used it for a week or so and went back to Neat Image that I find work better, don't know if it's better but it worked better for me.
In some photos I find Topaz Denoise to work better but it generates artefacts with "clear" parts, like clear skies and such. With detailed work it removes noise quite effectively.

Noise Ninja is better then Lightroom 2.X at least, haven't compared it with the new lightroom 2.5 update though, they have improved noise removing there. Still think Noise ninja is better.

Don't use Silkypix enough so don't know about that.

If you use the Noise Ninja Standalone, the file must be in either JPEG or uncompressed TIFF format.

For the Noise Ninja Photoshop Plug-In, it can read any file format supported by the host application. So if you are using the Noise Ninja Plug-in with Photoshop, you can work with JPEG, TIFF, RAW, PNG, PSD, BMP, etc.

I wonder if you can get better results when you apply noise reduction to the full version photo and then lower the resolution 50%?

It might be a fun lens to play with, but if you've a M and A 50mm f1.7 then I don't think it would see much use.

If you want a pancake you might want to look at a M 40/2.8, it's so good as the same as a DA40mm LTD, it's a K-mount but I have no idea what price they go for... not so much if I recall correctly but ain't sure.

It's of course very small though, 18 mm and with a focus & aperture ring
It at least gives you something different you already have.

I don't know the lens but the Pentax M 50/1.7 is also small with a length of 31 mm so would go for that one since the price is the same.

Also you don't need a m42 adapter to K-mount, then if you go for the Pentax.

You have screen and print.
With Screen it's 1:1 pixel magnification and print is 300dpi 8"x12" print comes down to 8mp at full print size.

Congratulations!

Decent weather? you mean rain to test out the WR of the lens

I can say the construction of that one is good, I've something similar for my K10D. There is a strap that goes around your wrist securing it in place so it's not like the one Jack showed you.

For the bright pentax letters, only pentax can of course use there logo and since that is their only handstrap you don't have much choice

John, that would be great but I just can't get them here in the shops. I can of course let them shipped to here but then I'm better of buying Elinchrom D-lite4 set

Still interested to know what you find.
