You will love me for this. Use intervalator or time lapse. It auto focuses on each shot. You can dial in the interval and number of shots.

Adobe discusses their plans for Lightroom and the cloud. Looks like Lightroom 5 will still be available stand-alone:
 Quote: Lightroom and the Creative Cloud
Adobe’s recent announcement around our Creative Cloud update has generated quite a few questions around how it will impact Lightroom 5. I’ve answered a few of the questions below and please feel free to ask additional questions in the comments.
Q. How much will Lightroom 5 cost?
A. We do not have pricing information to share at this time.
Q. Will Lightroom 5 be included as part of Adobe Creative Cloud?
A. Yes. Lightroom 5 will be delivered to Creative Cloud members at no extra charge when it’s available.
Q. Will I still be able to purchase Lightroom 5 outside of the Creative Cloud
A. Yes. Lightroom 5 will continue to be available as a standalone product, available for purchase as an Electronic Software Download(ESD) or as a boxed product with a traditional perpetual license. Lightroom and the Creative Cloud
LR is all that I really use from Adobe, so it sounds like business as usual for me.

And at least if she throws up on the K-5 it won't damage the camera...

Yeah, kids can be pretty annoying sometimes. But I've found that they more than make up for it with the happiness they bring during the good moments. And I've heard them described as an insurance policy for happiness in later life.
And although they did cost me one hobby (RIP my Yamaha YZF600R and Triumph Daytona 600), I never would have picked up photography as a hobby without them. They grow up so fast, so I'm trying to preserve these precious early years as well as I can, and beautiful photography seems like a good way to do that. And I must say, I get much more enjoyment and satisfaction out of my photography hobby than I ever did from my motorcycles. And it's a lot cheaper (and safer) too! Who knows, maybe someday when they leave the nest, I'll combine the two hobbies.
Yes, eBay would probably be your best bet for finding a used 28-75mm. But I recently saw one advertised here locally in Indianapolis on Craigslist in K-mount for $275, so you should keep an eye out there. (Although I just checked out the Canberra Craigslist page and it seems rather...barren).
Used copies on eBay generally go for $300 - $350...sometimes a little less, sometimes a little more. There's no used copies on eBay right now. The cheapest new one is from Japan for $449 US plus $20 shipping (to Australia). If you're wanting to get a deal on a used copy, you can setup a "saved search" on eBay and eBay will email you one is listed.

In the studio I don't like shoot-through umbrellas. They act like a light bulb, spilling light everywhere, but in an environmental portrait they can be quite nice. The trick is to get your shoot-through as close to your subject as you can while staying outside of the frame. But, this means that if it's close to one person, then it's not close to another, and the inverse square law dictates that someone in the shot will be underexposed. For this reason I only use them for individual portraits, or another way to go is one shoot-through for each subject in your shot.
You should also be aware that shoot-through umbrellas tend to be one stop less efficient than a white bounce umbrella, and about a stop and half less efficient than a silver bounce umbrella. That may be ok, but there are times when you'll be at full power on your flash and the shoot-through just won't give you enough light to work with. This is mainly outside on a sunny day.

Your K-5's specifications are 4928 x 3264 (16.3 MP) with a 23.4 x 15.6 mm CMOS sensor. That's 4.7 microns pixel spacing. The diffraction spot diameter for f:22 is:
d=2.44*N*(.55 microns)= 2.44*22*0.55=30 microns!
That means when you shot the photo, each infinitesimal spot of light was spread over a disk more than 5 pixels in diameter. When displayed at 100%, each point of light in the original scene is spread over 5 pixels on the display (almost 1mm). No wonder it looks fuzzy!
To prevent strong diffraction effects at 100% display, your f-number should be such that the diffraction spot radius is about the same as the pixel spacing. In your case,
N ~ 4.7(microns)/1.22*0.55(microns) ~ 8
Or, avoid high enlargements at high f-numbers.

If you feel that you are so subjected, you may, of course, exercise your human right to leave.
And for that matter, I did not come to this particular forum to read your opinions on morality. I think there's a forum on PF for just that purpose. I'm confident your comments will be welcome, or at least tolerated, there.

A "disgruntled Pentax owner" indeed...
So, let me get this straight, in July of 2012 you introduce yourself, stating " I am a beginner, living in Austin, Tx. I just bought my Pentax K-5 about 2 weeks ago. I have the kit lens 18-55, a tamron 28-300 3.5-5.6, Pentax A50mm/2.0, Zenitar 16mm. I'm just getting into photography as a hobby."
In the months following we see you buy a Sigma 70-200 f/2.8 HSM Macro II and sell it almost instantly, get rid of the Pentax 18-55 DA WR, the Sigma 70-300 DL 3.5-5.6 macro, the Tamron 90mm f/2.8 AF SP Di macro, a Pentax SMC FA 50mm F/1.4, a Mitakon 85mm f/2.0, a Sigma 28-105 f/2.8-4.0 as well as hunting for a DA*50-135mm.
Barely a few months later you "have to talk myself down off the proverbial ledge. Everyday I tell myself "just do it... Sell it all, and get a 7D or a D7000" because you lament the lack of K-Mount options?
Why in the blazes would you want or need a Sigma 120-300 f/2.8 or even know what to do with it once you would get it? Why would anyone here take this spoiled-brat whining seriously and add to the negativity that's been floating around so much lately?
Well, read my lips: go get a Nikon or Canon, please!

Do you want to just buy gear or shoot photos? What kind of images are you intending to take? Depending on your aspirations, maybe you'd have been better served with another brand. But it sounds like you just need to cool off and go shoot some stuff -- let the actual limitations in real experience preventing you from getting the shot you wanted be your guide, rather than just imagining you need this or that just because it is out there. Frankly, you don't know what you are talking about simply from lack of experience, so go get some before you go selling your system to buy another one with won't satisfy you either because you actually have no idea what you need or want. You did land on an excellent camera and there are lots of lenses out there, they're really are. But for now just use what you've got so you can make an intelligent next choice.
Unless your only aspiration is just to be a gear whore -- then don't sell anything and just buy buy buy...

Sorry to disappoint you folks but in my previous job this would have been useful and we were starting to use extremely wide view video cameras as well. Is it an insult to you when Pentax comes out with any product that is not specifically for yourself? Do you feel insulted if they come out with a new pair of binoculars or spotting scope or rifle scope? Should you be their only targetted market?
I understand your desire for a FF camera and perhaps the need to be able to have a meaningful upgrade to your camera at least once every two years in order to take decent photographs. But to feel like it is a personal assualt or insult that the corportion produces products for other needs then your own is very selfish. Depending on the specs we might have bought several of these cameras. Perhaps we should petition Pentax to fire any designer or engineer whose job is to work on something other than your next camera or a lens that you want. For all you know the people who worked on this might never had any input into a dslr anyway. But it does not matter as it is not for you. Some people appear to like the K01 and yet there are several on this forum who trash it each and every time as it is not a product they wanted. News flash: you are not the only person Pentax is trying to make products for. You want the company to be sucessful but in reality you really only want your next camera and lens and what other people want or need is not only immaterial but is a determint for you getting what you think you need. And I do realize that many of the comnments were light hearted and in jest but some of them were not and it is those and the constant bashing of all products you are not personally interested in that has gotten very tiresome.

I'm sorry, you're just wrong. First of all, the viewfinders are not really that great for checking focus, especially if your vision is anything but perfect. Even then a lot of people buy focusing screens and viewfinder enlargers just to have a better chance at nailing the focus. Modern DSLR's are made under the assumption that everyone uses AF, that AF works perfectly and people only use the viewfinder for general composition and not for checking exact focus.
Secondly, sometimes you are in a position where you cannot put your face right behind the camera, but with live view, you can still see the composition (and focus, if you have peaking). Peaking is a very useful tool and if its implementation doesn't cost an arm and a leg, I see no reason why it isn't included.

EV QUESTION
Because it doesn't make sense. The exposure compensation works my overexposing/underexposing the automatic controlled setting. Example :
In Av mode, you dial in +1 exposure compensation and the shutter speed will be one stop slower.
In Tv mode, you dial in +1 exposure compensation and the aperture will be one stop "more open"/brighter [i don't know the best way to say it]
In Manual mode you control everything, so what would the exposure compensation do? Nothing.
DOF and longer focal lengths
It does. If you get a 200mm 2.8 and frame a person, you'll get a nice defocus.
Here, for example :
That is a picture of my aunt using my Sigma 70-200 2.8 at longest focal length and 2.8 aperture.
If i had used a 24mm f2.8 and same framing, the background wouldn't be nearly as defocused.

Hi! I have switched from M85 to Samyang 85 1.4 and the short story is like this:
M85 is smaller, nicer to touch it and in some conditions something like magical :).
The Samyang - sharper wide open with less fringing then even top class lenses like Canon 85 1.2, Nikkor 85 1.4, Sigma 85 1.4, Nice and smooth render but sometimes when the magic of the M85 appears the samyang is a little boring without any bokeh only defocus. And the samyang renders colors much better. About sharpness - M85 is sharper from 5.6 to 11 a little more but only a little.
And the samyang is a little wider like 83mm or the M85 is actually 87mm.
The focus with the samyang is much easier when focus on distance but it appears that focusing the resolution table is another thing :) I didn't succeed to focus with the samyang better without liveview.
I have head to head comparison in bokeh but it is in PEF on my HDD and still not uploaded... no time for this.
Here is something that is impossible to be done with M85:

That's my take as well. I couldn't care less about the ability to buy new batteries anywhere in the world; I just keep charging the two sets I use. But being able to share charger with my other devices is a huge plus. As is the fact that I know I can still buy them 20 years from now. Try buying a proprietary battery for a 20 year old device...

Hold the quick-release button down (carefully, don't drop the lens!) and you'll be in MF mode :D
And for the record I did the same with my non-QS lenses a while back and I've never noticed any drop in screw-drive AF performance. Don't sweat it, but I wouldn't encourage it.

Remove the lens. Look at the AF screw drive in the camera's lens mount ring as you select MF and AF with the body switch. In MF the screw should be retracted. If it's NOT, your AF switch isn't working properly and AF is mechanically engaged even though the switch is in manual.
If the screw drive IS retracted when in the MF position, any unusual condition must be in the lens itself. Compare the lens with other AF lenses.
Note: the AF indication (and beep) in the VF operates regardless of the MF/AF body switch position (although some effects may be deselected in the Menus).

I have this exact issue with my K200d. Unfortunately when I went to pick up the camera one day a month or so ago, the strap caught on a stool, pulling the camera out of my hands. Unfortunately the camera swung down and struck the bottom of the stool. Fortunately, the only issue is that the AF/MF switch, while it does move, doesn't actually switch the camera out of AF. While searching for potential fixes (not like I really thought there would be), I noticed this seems to have happened to a few K200Ds out there.

You missed one possible reason to shoot RAW, one which most certainly applies to me:
I SUCK. I blow exposures all the time. I forget what I have WB set to. I switch modes and don't realize I had different ISO settings. Pretty much a disaster behind a camera.
Why should I be relegated to my screwed-up JPG output when I have the opportunity to try to salvage it by changing settings in the RAW file? I'm trying to get better, trying to remember just WTF it is that I'm doing out there, but I don't always get it right.
