Don, did you know that most editors won't open a photograph of
a bank note, at least not a British one. That's why it takes so
long to open images the software scans it first for banknotes
Obsolete notes no longer in circulation are probably OK.
The do make good tests as shown here: link

I usually find when testing by photographing banknotes etc.
3 shots of every 4 are often out at say f/2. The sharpest is
often the one with the biggest file size MF is usually
the most reliable. I've never tried live view. I do use a 2x
Refconverter though. The Eye-Fi card also comes in handy,
because I can see the shot straight away.

I'm probably a little early in my Pentax life to answer this question properly - to explain. The K5 and supporting lenses have been purchased to back up my Leica M and Leica lenses, for when they are not the right kit for the situation before me.
Therefore at this moment in time, my all time most useful lens on the Leica M8 is a Summaron 35mm which left the Leica factory in Solms on the 4th May 1950. For me it is stunning, and that is all that matters. My least useful lens was a 90mm Leica, and so that went in part exchange for the Pentax K5.
Now l know that this approach won't suit everyone, but l hate being on holiday with a bagful of lenses and standing in front of subjects wondering which one to stick on the front of the camera. I therefore challenge myself by only taking one lens with me.
In a weeks time l disappear up the Norwegian Fiords with just a K5 and my FA43mm limited. I have had this lens for a couple of weeks and whilst not having used it extensively, l am starting to get the feeling that me and it and going to spend a lot of time together, unless the FA77mm ends up in the bag.
At the moment, l have to say that the FA43mm limited looks like it will be my most useful lens - what will end up the least useful, at this moment l haven't a clue.

this is prone to change over time... but for the moment:
my m50 1.4 is most useful, for video on the kr. Which I'm using a lot...
my sigma 400, least used for many years in a row....

I use PEF but may consider changing and updating my whole library if Pentax continues to be so... unstable... sold twice in a few years... seems like DNG might be safer for future support.... I mean if one of my old computers with an old copy of Aperture was to die... how would I open up images from a format that went extinct in the future?

Welcome to the forum btw, didn't saw you were new
yes it is.It's always fun to discover new things
Welcome to the forum btw, didn't saw you were new
last weekend my wife came to me with our kr complaining it was acting very strangely... image playback was not working, lens constantly hunting, live view not working right..blacked out lcd, no menus showing up...still able to fire the shutter though.. just plain wonky... naturally the first thing I did was pull the battery and restart the thing.. but no, still wonky.... I pressed the shutter button and knew instantly something was wrong...
on close inspection... a spec of sand wedged in the shutter button, keeping the shutter button half depressed...
rocket blower and fine sewing needle got the grain of sand out and all was fine in the world again.
so naturally this thread caught my attention......
Welcome to the forum...

As regards the MTF curves, they are what they are and it's not unknown.
Another example is the Voigtlander 50mm f1.8 Ultron of the 1970s, where the edges were corrected more than the centre.
However, the upshot is for the 35mm f2.4 that it's an excellent lens, tremendous value for money and although it's not as good as the 31mm it's more than good enough for critical use.
because I run several systems of cameras, including Pentax d-slrs, Sony camcorders, and go-pro, and I have to run audio gear from Peavy, Bose, Rode, Sony, Audio Technica... As regards the MTF curves, they are what they are and it's not unknown.

to create our multimedia projects (not to mention all the Apple systems and software)...
COST is always an issue for us when buying gear. We simply do not pull in enough money to justify the lenses JR has just acquired. I wish every company we deal with had the kind of bang for the buck, outstanding value as Pentax is offering with the 35 2.4. And the KR.
