keychain camera

I have not seen that one. Some seemed to like the aiptek pencams in the past. There is a tiny cam yahoo group if interested.

Here's a mini-review of the camera. I haven't used it on the trail yet, just at home.

pro:

0.7 oz
good reviews on amazon
The seller was responsive when I called with a problem.

con:

The first one they sent me was defective, but they replaced it promptly.
It's hard to frame a shot.
If you hold the button down too long, it takes video rather than a still photo.
There are 4 buttons, 2 of them fake. None of the buttons are labeled. (It's sold as a spy camera that looks like a car-key fob.)
The documentation is in fractured English.
There is not much obvious feedback (like an audible click) to tell you when you've taken a photo.
It doesn't take good pictures in low light.

Although my list of negatives is fairly long, I'm actually reasonably happy with it. The alternative was going to be that I wouldn't take a camera on my trip at all. The weight savings compared to a normal point-and-shoot camera is about 4 oz, which is a lot to me — that's how much my torso pad weighs.

A lot of those mini-cameras are just cell phone style cameras without the cell phone. If it works for you, great. I find that cell phones take lousy pictures. I have a few little cheepo cameras my kids play with that are the same. The problem is usually the cheap plastic pin-hole lense.

Cell phones keep raising the megapixel count on the cell phone cameras but as long as you have a pin-hole iris and a 3mm lense it does not matter if you have 1 or 100 megapixels, your image quality will be bad.

Pictures are a record of priceless moments, especially moments with kids and grandkids. They will definately appreciate them when they are grown up.

I tote around a DSLR and several lenses when not backpacking. When in the woods I take a 4-5oz point and shoot. Some tote their DSLR, whitch I find too heavy. I guess we all have our trade off points.

In my opinion take a small point and shoot. A picture woth taking is a picture worth taking well.

I just got a Pentax w80 for father's day. It's completely waterproof. I haven't weighed it yet. The picture quality is great in bright light and poor in dim light. It records HD video at 720p 30fps which is really nice. Either way, the picture quality is leaps and bounds better than any cell phone.

Here are the results of field testing the camera.

The image quality is abysmal, but that's what I expected, and I was making a conscious decision to save four ounces by accepting bad quality. Here is a sample landscape:

The problem that I didn't anticipate, but probably should have, was that its battery drained itself after the first day of my 12-day trip. Presumably this was because the buttons were exposed, and they got depressed while the camera was in my pack.

If the image quality wasn't so ludicrously bad, I would probably put some effort into finding a way to store this thing in my pack without the buttons protected, but as it is, I don't think it's worth the effort.

It's frustrating that you can't seem to get any middle ground in terms of weight and image quality. There just don't seem to be any decent options below about 5 oz.

Pentax Optio WPi is 4.9 oz if you could find it on a gear swap.

Im not sure if there are any lomography buffs here, but the vq1015 is a phenomenal keychain camera that weighs next to nothing. It has its set of limitations though. It is awful in low light and if you dont like high contrast/vignette I would stay away.

Worth at least taking a look.

I've had 2 of the pentax w series cameras. I love them for being waterproof and taking reasonably good pictures. Not near as good as my DSLR but still good.
