maybe a difference between dng and pef raw formats?

I'll doublecheck, I usually use DNG, but there's a chance I could have switched to PEF and not noticed.

Google is changing a lot of stuff with google +/google photos being unrolled... so maybe it's related to some of those changes.

If I attach a photo to a forum post, are you guys able to see the exif data?

Class A, I'm sorry if I've come across as not being greatful for all the help that's been provided in here.
And I'm sorry if I haven't sufficiently appreciated your grateful side. All good then.

I don't think that the lens and/or file format are causing issues. The noise is a combination of undesirable camera settings (leading to underexposure) and the K-7's relatively poor tolerance against such underexposure. The K-7 is not bad at all, but a K-5 would make a big difference regarding image noise.

There's definitely a ton of videos of people with their k20/5/7/10 underneath a shower or under a faucet or pouring a bottle of water all over them.
These are all "no pressure" exposures to water. A dunking into a bucket of water would be something else; I haven't seen something like this.

Honestly, I cannot say what amount of time a K-7 + WR lens combination would withstand a dunking. I'm guessing not more than a few seconds.

If a camera ever gets drowned then -- if there is hope at all -- the key is to withstand the temptation to immediately try out whether it survived. Let it thoroughly dry first. If the contact has been with salt water, I believe one should first make attempts to remove any salt, if necessary by using distilled water.

So again, I don't think that the 18-135 has any optical problems you are suffering from but I don't think it provides the protection you are looking for either.

Seems like a waterproof housing or a waterproof bag which you only unpack when it is a 100% safe to use the camera are the only solutions.

I can see the exif data. Nice shots, btw.

Picasa generally does a jpeg conversion when you want to upload a raw photo to picasaweb... It used to be that when I did that, the exif data was viewable on the displayed jpeg (those cave shots I posted were raws prior to uploading, and their exif data is posted. ).
Maybe if you convert to jpeg first, the exif data will be preserved.

I'm generally pretty good about that. And have access to vacuum dessication chambers in the lab. I've rescued many a wet cell phone

It has a pelican case or 3. The issue is just when I decide to take it out.

I bought that once to try it out but it was absolutely huge compared to the K20d, which was slightly wider than the k7, even though the k7's a bit deeper.

I ended up returning it after putting the camera into it once & deciding it was unusable given how much spare plastics ther was compared to how big the camera was.

I made a drybag for the camera once. It worked fine for keeping the camera waterproof but was awkward for using the camera. Pics are there, if you want to try or some up with some improvement. I'd probably try plastic welding a narrower spot for the lens to fit into in the drybag bottom if I was going to try again. I'd suggest something better than lexan for the front glass, but I'm not sure what.

Just make sure to test it with some towels or something like that a few times before using it. I left mine in a hot tub full of water for a couple days.

Ahhh... I was hoping the finger inserts the DiCAPac WP-S10 Waterproof Case would make it easy to use the camera controls. I also have a Battery Grip on the K-7 so its a little bigger. Good try at the home job tho

I just currently pull mine in and out of a dry bag. Only other thing I was thinking of was a good quality deck bag with dri-seal.

I must stop falling over in my Yak...

I've not seen or used a 18-135, but must say, I love my 16-50.

I actually haven't fallen over in.... Okay, so someone flipped me over a couple weeks ago after a water fight got a little violent.

I'm taking the 18-135 out again tomorrow, a bit of the same location since I know there's lots of birds, and I want shots of fast moving animals as part of it. And I'll get off on a dock at some point and do some more rigorous tests against other lenses.

I have been very tempted by the 16-50. I would like a fast zoom or two. Fixed lenses are great, but it can be slightly frustrating when you're photographing people and constantly switching lenses. I was photographing my cousin's wedding in Scotland a month or so ago, and with the small dark rooms in the castle or the small dark town hall, and the press of bodies and speed of the dancing, it was pretty challenging to get good shots.

If there's somewhere you can get the dipac bag or try it out and still return it easily - go ahead and try it. I could be overly picky.

I don't use a drybag just because they take some work to roll correctly to make sure they're watertight and they don't provide padding. I generally use a pelican case, because it'll also protect the camera against impacts with rocks or whatever while in the kayak... It's also fairly easy to get in & out of quickly... Drawbacks are that if you have small hands, those clasps can be hard to move and they are noisy, so you'll scare away wildlife. I had a friend tell me of another brand of drybox that was easier to open & less noisy but I'd already bought the pelican so I can't remember the name off the top of my head but can ask him again if you're interested.



The pelican 1200 is borderline too small for the k7, but i use it anyways... it's not deep enough to fit a foam on the bottom of the k7 & foam on the lid of the pelican case & still close. So I just take the foam off the top & it will close... and since the inside is pretty much the height of the k7 it means it doesn't rattle... You can fit another lens or two, depending on how big your lenses are. The pelican has these flanges that go down from the hinge on the back, if you drill through those, you can insert some string through to tie them to the decklines of the kayak on the back, and then you can run line through the handle on the front to tie it down on the front. I use prusik knots which you can adjust the tension of, so it doesn't wobble back & forth on the deck (I also glued minicell foam to the bottom of the pelican so it doesn't mess up the kayak surface)...
Amazon.com: Pelican 1200 Case with Foam for Camera (Orange): Camera & Photo

The pelican 1300 is about the same footprint as the 1200, but an inch or two thicker, so it fits the height of the k7 better with padding, but it's that bit taller to make it catch the wind more or get more annoying on your front deck.

If you're interested in pics, I can send you them on how I secure it on my deck.

If you try a deck bag, look very carefully at how they seal & test it under pressure before trusting your camera to it. The ones that I've tried have let a small amount of water in where the waterproof zipper ended... That was enough to make me not trust my camera in them.

And... what sort of paddler are you? If you're high angle or a wing paddler, a deck bag is gonna get in the way of your stroke. So's a pelican case for that matter,but at least a pelican protects the camera from impacts

My annual kayak ride is on a lake and in good conditions, so not much danger of flipping except getting in and out. I've always used the 55-300 because I'm mostly looking for the loon family that nests on the lake. I use TAv mode, with 1/350s and f/8, and auto ISO set from 100-1600. Depending on light, I like to go higher ion shutter speeds whenever I can. I'd much rather have noise than motion blur. Note, I'm stationary as possible when I'm taking photos, otherwise the 1/350 would be too low.

Not really sure what my "style" would be called. I currently have a Black wolf deck bag infront of me, that at times I shove the camera in, but must admit, my stroke is low and sometimes I hit even that. I paddled around Holong Bay in Vietnam a year or two back with my camera and lenses in just a dri-sack in my lap, The kayak didn't even have a skirt, had water, about an inch somethimes in the bottom, camera was dry in the bag, but, I'm glad I can say, I didn't dunk it, dont know if it would have survived that. I did find a bigger, supposidly completly waterproof deck bag, but seeing how I hit the tiny one I currently have, not sure if it will be anygood. Thats why I was thinking the dipac cover. Hmm, might think more aboot that??? I do like those pelicans, its just the bulk I'm unsure about. My Yaks quite old, and has more than its share of "rashes" on it, so not really concerned with what a box rubbing around on it might do, but you are right, you can do some damage with a paddle, I wiped out a fishing reel once, when I had my rod secured under a deck rigging.

2.8 is faster than others, but, if you were in dark small places, it still would be a challange, best thing is to get a hotshoe flash, and run a softbox on it, actually, use of a softbox is what I prefer all the time, gives much better , more natral light, even in fill flash applications. Just set the flash to overexpose +1 to compensate for the loss. Going to weddings in castles in Scotland, now your just showing off ( )....hahaha.

Your lucky to get out in your Yak so often, I'm lucky to get out once a month..

good luck with your next outting, see how that lens goes with a few of the suggestions given... I personally only use Picasa for quick gallery veiwing, I've seen it do some wacky things creating the jpgs as far as colour casts and general quality of the pic, I do all my PP in Photoshop.

I'm showing off with castles in Scotland... But I also kayaked there with Gordon Brown And what about you showing off kayaking in Vietnam! All I did in Vietnam was swim in an oily beach and ride around in someone's boat with eyes on it.

I guess I've been lucky with picasa. Or am not picky. Except about this lens.

I couldn't go back to where I was last week because high tide was 8 am or 8 pm, and it was impassable otherwise. I had a friend kayaking with me, so I didn't have as much time taking pictures as I wanted. We went 26 miles, and I ended up doing my first combat roll when we were playing in the current at the base of some falls - the pelican case with k7 weight swinging on the deck lines does screw with my roll a little bit.

It was a full moon on the paddle back with the monuments in Washington DC lit, so I tried some night photography out on the water, so we'll see if I actually got anything usable.

If you want to protect the sides of your kayak - you can get clear shelf paper and cut it and apply to your kayak sides.

Unfortunately, I'm only going to be able to look at these on my tiny netbook screen for a few days and it's hard to really see pics well in that format. Not to mention a netbook processing raw files is a bit painful. But i'll be out tomorrow evening, there's a concert series that goes on at one of the Baltimore piers, so I'll put in a bit early, explore the harbor, listen to the concert & paddle some more in the full moon.

And... You should get out more!

GORDON BROWN!!!!!! Crikey...... Who the heck is that......................Hahaha

I did that too!!!! and it wasn't oil, and dont ask what it really was. Actually all boats in Vietnam have eyes on them, local custom thing lol, funny thing, somehow I didn't take a photo of one.

I had a friend kayaking with me, so I didn't have as much time taking pictures as I wanted. We went 26 miles ..... I tired just thinking of 26 metres......., and I ended up doing my first combat roll ( Excellent, I specialise in half combat rolls myself )when we were playing in the current at the base of some falls - the pelican case with k7 weight swinging on the deck lines does screw with my roll a little bit.

Yakking at night, must try that sometime, night-time loves an ultrawide lens.

If you want to protect the sides of your kayak - you can get clear shelf paper and cut it and apply to your kayak sides.

The "Belafonte III" isn't too precious, just a big plastic boat, lots of "custom pinstiping" on him, still a good cruiser tho at 5 metres long.

Cool, sounds like a great night out, Try a monopod for a little extra support maybe??.

And... You should get out more!

Yes, yes I should.

Hope you are happier with your pictures from your last outing, honestly, some times it takes time to get used to a lens and how it reacts, I know I have to adjust how I do exposures with all my different ones. Should have a DA*300/f4 to play with soon..

It's not worth the eye strain of looking at these on my netbook to try to tell which exposures were sharper/whatever, but it at least did this last night:
