Think about it this way:
If you use on-PC software, all you need is something that is faster than your keystrokes or mouse clicks.
Like Nigel says, you do not need a super duper monitor, but a big one is nice.
A big one that is matched to your printer is even better.
I used to use a 17" square LG, and what I saw on the screen came out of the printer.
I replaced it with a 22" widescreen LG, and have to make a set of adjustments in PS or elements to get the printout I want. It only takes seconds but those seconds eat up any speed advantage the PC has.
An accurate (but totally useless) answer would be a PC that is fast enough for you, with a suitable monitor.
Think before you buy!

And the same question used to be asked about PCs for word processing years ago.
Rven when processor speeds were down to a few hundred Hz, and RAM at about 640K, the PC was always faster than the person at the keyboard.

Oh Wow!

Agree with Chrism8 about taking the cars out of No 2 image.
But also think about cropping the top 15% or so to get rid of the upward curve of the tree line. This draws the eyes away from that wonderful loco.
Reso has just shown you what a tight crop can do ...

Geoff

First shot is a cracker. But ... ...
Lighten the shadows by about 25% and then turn it into black and white, and it is a real stunner.

The problem that I see is with the email notification that there is a new post to a thread I am following.
I click on the long link. I get the PU heading menu, I am told that the notification is reset.
I wait
I wait
I wait
I could have a cup of coffee and still be waiting

1 - Buy via Amazon. Any probs and go back to Amazon and let them deal with it.

2 - Buy from John lewis. they will pricematch Camera Centre as quoted here:
https://www.pentaxuser.com/forum/topic/john-lewis-and-the-price-match-55097

If its old stock from "somewhere", think again.

Geoff

What's going on is a well-known fault with a lot of the MZ- / ZX- series.
A little plastic cog has given up the ghost and a repair is more than the camera is worth.
My MZ-50 died in exactly the same way.
I nearly bought a replacement body from Kree on this forum, which had the cog replaced with a metal one.
He may still have it if you want to go down that road.
Geoff

1 - It's a bump!
2 - Pentacon now sold to Kree
3 - Having searched my soul, I have decided that I do not want another film body.
That cuts my wish-list down to *istDS, or K10, or maybe a K100, bodies only, do not want to trade for much else.
4 - Open to offers on anything.
Geoff

While I have reduced the amount of kit I have by several lenses and a K20 body, I still have too much, and most of it is stuff that I cannot physically use now. The crunch came when my MZ-50 died (the well-known mirror drive gear fault).
So, either the surplus kit has to be sold, or I need a body to mount the remaining lenses on. Hence the “Swop or Sale” headline.
I would prefer to stay digital, although the MZ-50 was light enough for me to handle with relative ease (my MS is getting slowly worse) and an X-5 has solved the problem of handling long and heavy lenses.
Now comes the next problem, if I am offered an interesting swap, do I try to keep any/some/all of my shorter Tamron A2 gear (with 2 x KA adapters and one K), or do I use the adapters to make a particular lens more interesting? Decisions, decisions … .
So what might I like? An *istDS would be more interesting (being smaller and lighter) than a K10 (also interesting), but an MZ6 or an *ist might tempt me just as much.
I am always open to offers, or bundling (but acceptance is not promised).
All prices are including postage/courier within mainland Britain – I am not looking to sell outside this area.
Payment by DBT please (no Paypal).
