You can select f/2.8, but as you zoom in from 40mm to 80mm the aperture will open up only a teeny bit, until it reaches 20mm in diameter. (f=80mm, f/4 = 20mm) When you select f/2.8 on the aperture ring, it just means the aperture will stay open as wide as it can go for any given focal length.

Try the Corkscrew Swamp Sanctuary. There are a few different habitats to walk through - open grassy fields, heavily forested swamp, a few different things. This should be a good time of year to see it.

geoles2, have a look at this online depth of field calculator. You can select your camera, focal length, aperture and focus distance. If you spend a little bit of time playing with the different variables, you'll have an easier time understanding how they all interact.
It seems that you automatically assume you have to use f/2.8. If you're shooting a group indoors, bump up your ISO a little bit, stop down to maybe f/4, and if your shutter speed is still going to be slow, put the camera on a tripod and tell everyone to hold still.
There are all kinds of possible reasons why your photos aren't sharp. We're just guessing until you show us some.

Camera lenses designed for 35mm film won't cover a 35mm x 35mm sensor.
A 35mm film frame is nominally 35mm x 24mm. The diagonal of the frame (the largest dimension to be covered, hence the diameter of the image circle) is about 42.5mm. The diagonal of a 35mm x 35mm frame is 49.5mm.
I guess you could design the body so the lens would be farther from the sensor, thus increasing the size of the image circle, but wouldn't that cause other problems?

Rajith, a quick look at the V5 on the Gadget Infinity website shows a cable with a PC connector on one end. Have a look at the last picture, here.
That would mate with the PC terminal on the camera (if you're looking at the front of the camera, it's just to the right of the lens mount, on the mirror box. That would appear to be your answer, though you'll still have to come up with some way to secure the trigger so it isn't just hanging off the cable.

TigerLord, it seems to me that *anything* running on batteries (AA or Vagabond) will have slow recycle times at this time of year in Montreal. That's just what cold weather does to batteries. If you have some way to keep them a little bit warmer, the performance should improve.
Separate issue: 2600mAh refers to the capacity of the battery, not how fast it'll dump current into your flash's capacitor. I've found that Sanyo Eneloops will charge your speedlight faster than any other brand I've tried. And the "classic" Eneloop is rated at 2000mAh.

Try moving the shutter speed dial to all the different speeds and see if one of the speeds isn't a manual release. (This works on some Nikon film cameras, don't know if it'll work on a Pentax.)

A technical point - unless there was a specific arrangement made beforehand, the photographer does own the photographs. But without a model release (in these particular circumstances), he/she has no right to sell, license or distribute them.
Street photography is less restrictive - the important test is "reasonable expectation of privacy." If someone is in a public place, he/she is pretty much fair game. But a model release is always a good idea.

I think that particular definition is in the eye of the beholder, so to speak. Maybe the judge wants to see motion, or juxtaposition, or contextual contrast.... Or maybe the judge doesn't have a clue about how to express what he/she means. Don't be afraid to ask for a specific explanation. Asking doesn't mean you're dumb, it means the judge isn't very good at being clear.

Rico's solution is great if you're building a two-flash shot, and if you can live with one of those flashes being the one built into the camera.
If you don't want to use the built-in flash at all, your next move is either a TTL cable or a radio trigger. The cables usually go for around $30 for a camera-brand cable, less for a knockoff. The triggers cost a bit more, but they give you the option of placing the flash farther away than a cable can reach. Even the cheap ones will get you 50 feet, usually. All of the above can be found on eBay.

...and once you do get one or more flashes, your next stop is the Strobist blog. You'll learn more about flash at that site than anywhere else on the web.

My point was more that you don't really need to hide the camera - just yourself. If you have a long enough release cable, you're good to go.

Honestly, you don't need a blind to shoot little birds at a feeder. I set up on a tripod about 5 feet from the feeder, with two flashes on stands about the same distance away. All were set up with Pocket Wizards, I sat inside and waited to push the button.

If someone drives up, says "photography isn't allowed" and then drives off, photography is allowed again as soon as they're gone.
It reallly has gone too far. I took some pictures recently of a surprisingly picturesque bus depot in a southern U.S. city, and was told by a security guard that I really wasn't supposed to be taking pictures (from the sidewalk - across the street!). Even though I was in a public place, she said she was supposed to call the police. She didn't, though, because she wasn't as paranoid as the people who are trying to keep us from taking pictures.
DeadJohn, though I'm originally from the Philly area, I've never been on the grounds of the Navy Yard. No idea about whatever rules they have. But next time I cross the Girard Point Bridge (the big one that runs just above the area where the mothballed ships are moored), I'll stick my camera out the window and take a couple dozen frames just out of spite.

I have an official Pentax strap with the "earless" lugs, on my 645N. Seems to work just fine... Once you get it on the stud and locked, it's not going anywhere. But it does rotate freely.

You can find the best online depth of field calculator here. It gives you a great visual representation of how aperture, focal length and focal distance interact and what they do to your depth of field. It will also give you good information about hyperfocal distance.
If you have a smart phone, there are depth of field apps you can download (usually free) that are very handy to have in the field.
