Originally posted by mooksf I ended up going for the K5 with the two lenses, as it is in excellent condition with less than 7k shutter count vs the K3 with 20k and the 18-55
Both 7k and 20k are extremely low for this class of DSLR cameras. The K-5 series is a great handling design with an exceptionally well-placed control layout. For a far better all-around but fine-performing zoom lens over the 18-55mm, I highly recommend to consider getting the DA 18-135mm WR lens. It would be ideal as a single lens for the uses you describe. Its imaging and especially its excellent AF performance on any of the Pentax bodies, but especially the K-5, since the main upgrade of the K-5 II was in AF performance. The original K-5 sometimes had AF issues with some lenses, and the DA 18-55mm is known for AF that is not always accurate nor is it among the fastest on any camera body, though a good lens for what it is. The build of the DA 18-135mm lens is miles better, and yet it is remarkably compact for its zoom range. I still have my K-5 original and can testify with this lens on it, one is hard-pressed to tell if one is shooting with it on the K-5, K-5 II, or the definitely-AF-improved KP! I've had this lens for over 10 years and have used it on many Pentax bodies, all with great results. Not macro, but it can even do very fine closeups. You can get an idea of its capabilities in the lens discussion section of the forum in the thread- "DA 18-135mm WR, Show us what it can do" and start with the last page (most recent) and work backwards.
Perhaps your camera will come with the owners manual, but if not you can download it free from the Ricoh/Pentax website. When you get the camera, it might be a good idea to do a reset to factory standard of all settings, unless that was assuredly already done by the seller.
If you intend to shoot highest quality JPEGs, at least until you familiarize yourself with the camera, I recommend implementing "Fine Sharpening" in the Custom Image menus, at least in the most often-used "Bright" category. There are 4 buttons surrounding the ok button. The one to the right is a direct link to the Custom Image menus. Once you bring this up, the 4 buttons will serve to navigate. Once in the "Bright" category, you can scroll down to the Sharpening adjustments. In this category, the Sharpening level is by default up by +1. With the K-5 series, I like to increase one more notch to +2 level. Then you can implement Fine Sharpening as well by using your thumb dial to put an F by the S. Once that is done, just hit ok, then again ok, and you'll be back to normal screen conditions or just shut off the camera.
You will, I'm sure, enjoy using the exclusive and unique Pentax Hyper System. If in the P mode, which is often useful, and you would rather have a different shutter speed or aperture than what the camera has chosen, just go ahead and choose your preference by using the rear thumb or the front finger dial, and the camera will simply instantly obey. You are now in Hyper Program operation. The first click will freeze the current value, further clicks will change the value. This switches the camera instantly into either Tv or Av operation without having to first change the mode dial before making your change. A touch of the green button instantly restores full P automation.
If using the M (Manual) mode, instead of the usual twirling of controls to adjust aperture and shutter speed to achieve a meter-centered exposure setting, you can just hit the green button and this will be achieved instantly. You are now in Hyper Manual mode. This is also great for quickly taking spot meter readings around a scene. If you then would rather have a different aperture or shutter speed, first hit the AE-L button to lock your exposure, then go ahead and choose your preference and the other will follow along to preserve your exposure value. The Pentax Hyper System is the fastest operating system out there for making quick adjustments on the fly.
