A couple K5 shots (100 vs 51200)

So I took a series of test shots with the K5 through the entire iso range. If anyone wants the raw files to look at I'll be glad to post them somewhere, I just need to figure out where.

In the meantime, I thought I would just post two downsized images for now, one at iso100 and the other at iso 51200. Both processed in LR3 using the default settings, except I bumped up the color noise reduction a little on the 51200 (to 50). I have to be honest, I have no idea what that means exactly as I just downloaded LR3 a couple days ago and have next to no experience processing raw files

Then I downsized them and I applied light sharpening as I normally would if I were posting something on the web. Again, I was just looking to see if 51200 was even potentially usable (without going through a lot of trouble) for stuff like web postings. Not saying I would make a point to use 51200, but it could be worse

EDIT: here are links to the RAW files (via Multiupload)

100, 200, 400, 800, 1600, 3200, 6400, 12800, 25600, 51200


ISO 100 (K5 + FA77, f/8, 4s)


ISO 51200 (K5 + FA77, f/8, 1/125s)

I think 51.000 will definitely be usable for small prints or web. Can you try the same shot with very bad lightning and same high iso - because in this condition we will use this iso, extremely low light available.

There wasn't a ton of light for these shots (it was indoors with no direct light from the window; the ISO100 shot needed a 4 second exposure), but I can certainly do another set with the blinds closed or later this evening.

With noise like that, the photos are usuable for smaller prints.

I don't print a lot of photos, but I got some free prints some time ago and decided to test how noisy ISO 1600 photos from my K10D would look like. The prints was.. ehm... "a half regular A4 paper"-size and there was nearly no visible noise and the photo looks great.

I guess 51200 on the K5 is not as good as 1600 on the K10D, but it's not that big difference. Will be great when my K5 arrives!

You're more than welcome to the raw files. Let me figure out somewhere to put them and I will get back to you. In the meantime if you want me to send you a few of the raw files by email I can do that too. Just PM me your email address.

Thanks for the link. I am uploading them now and will post links in about 10-15 minutes once the almost 300MB (!) of raw files are uploaded.

I actually installed an extra 2TB drive in my computer the evening before the K5 arrived. I had a feeling I would need it
