Thanks guys. Looks like there is a wealth of knowledge in here especially regarding using non-645 lenses ;) Beautiful flower shots lenticular. Keep them coming since as we approach Winter and you approach Summer they will be welcome here to help me on the opposite hemisphere get through the cold, dreary days ahead.
Here's one taken with the normal 55mm...

Maybe the 11-18mm is a macro. Covered up the distance scale, covered up where macro would appear, covered up the focus limiter.

I own both the 645D & Z. If I could keep only one it would be the D for the uniqueness of that sensor and having purchased it new would lose too much on the deal compared to the Z which I purchased used. I was very happy with the D & the only reason I bought the Z was that I put a bid on a 1000 shot Z,55 & 90mm lens no else decided to bid on. As for the focus screen, when I bought my 645D I only had manual focus lenses and wanted a more accurate manual focusing experience than the standard screen provides. I searched in vein for the AB- 82 or whatever its called split screen version. I did come across the all microprism version for a reasonable price but decided to try something else first. I took the old standard screen from my original pentax 645 film camera(first version), snapped off the tab to the side as they have a different position to the later pentax 645's. Using a nail file I smoothed out the remaining squared off sections at the base of the tab. This is important as the first time I tried the old screen on my new D the focus was slightly out. Upon investigation the screen wasn't sitting perfectly flat on the holder and I thought I had just hacked a screen for nothing and wasted my time. Turns out I had not filed quite enough of the tab base square section off to let it sit in the surrounding holder correctly. Once I had removed all traces of the tab, it fitted perfectly and presto, I had a combined split/ microprism screen that I was use to and did make manual focusing considerably easier and a lot more enjoyable experience. You have to remember to put the screen facing the same way as it came out of your film camera as you no longer have the positioning tab to prevent from putting it upside down in the camera. Also no longer can you handle the screen with tweezers via the tab so I just used new cotton gloves & handled from the edges & a good blow down with a rocket blower before you re-install. I still have it in my pentax 645D now as I tend to use that camera more with manual focus lenses and the Z more with AF lenses. Only downside is a slightly darker finder but I can always change back to the original screen but haven't been tempted to even when using AF lenses. Metering ,AF and all functions remained unchanged.

Your choice just shows there is no such thing as the universally best camera. In some cases, the exact same reasons that one person hates a certain camera (e.g., "slow" performance, or bulk, or rendering) are the same reasons another person loves it.
The spectral responses of CCD and CMOS cameras are simply different. That implies that no amount of post-processing can truly convert a CMOS image into a perfect replica of the CCD one. The exact spectral make-up of the light from scene as measured by a CCD camera is simply not in the data coming out of the CMOS image. That said, BigMacCam has created a set of presets that do a good job of approximating the CCD look (Get "that CCD look" with the K-3 / K-3II and Lightroom - PentaxForums.com).
Enjoy your 645D and best wishes in finding the venerable AB-82 split screen!

great narrative of your thought process leading to your decision. For my purposes (landscape, studio, portrait), I would definitely opt for 645D over K-1 for the large CCD sensor. Having used both, the CCD (if you do not require high ISO) is superior in rendering to much less expensive(but efficient) CMOS.
However, once you get above ISO 800 on the CCD, it starts falling apart whereas the CMOS typically hold up past ISO 6000 IMO.
Congrats and welcome to the MF-ers Club!

The focusing screen is the main culprit when it comes to metering inaccuracies when using the viewfinder and M/K lenses. Today's focusing screens are designed to be bright when the lens has a large aperture (fully open). But they get relatively too dark as the lens is stopped down and fools the meter, making the camera overexpose. Note that in view finder mode the light meter meters off of the focusing screen.
This is not an issue with "A" (and newer) lenses with the aperture ring set to "A" (if a ring is present) because the camera meters with these lenses wide open no matter what aperture is set. M and K lenses are metered "stop down", i.e. at the actual aperture set which fools the meter on today's cameras.
In live view there are no issues, since the focusing screen is out of the picture so to say.

Since I couldn't update my last post the way I wanted, I'll start a new thread for my Makeup Calendar project. I'm working with two makeup artists (sisters) that will do this project as their high school exam. I will shoot every picture for their calendar in March and April of 2014, the calendar will be presented in May 2014. All shots are now made and presented below.
