FF is Full Frame. A bit of a silly same really as it should be called 135 frame.

Unfortunately they only refer me on to the importer intro2020 who are not so good.

I don't know if your realize that businesses get charged a percentage of the cash they pay in and withdraw from banks. It varies depending on the tariff they are on but a lot of the time it costs more than accepting cards.

Debit cards tend to have a flat fee of 10p-50p per transaction where as credit cards are 2-5%, Amex being the most expensive at 5%. MC and Visa are 2-3%.

You do ha e merchant terminal expenses but there are cheap ways of running them as well.

And businesses pay to pay in and write cheques.

I assume that in the Netherlands mobile card terminals are used a lot more than here. They are a rechargeable terminal with a gsm modem/SIM card slot.

Lots of new lens profiles including for 3rd party k-mount lenses.

I agree, the 77 and 12-24 would be good to have with you.

Nothing wrong with Pentax for wedding work. As long as you know how to use your specific equipment it is as good as any other and the lenses are quite unique.

As for equipment...

The K-x is very capable. You do need a second body if shooting a wedding though, both for flexibility and backup. What lenses do you have? Fast lenses are important for subject isolation and good bokeh. Do you have any lighting equipment?

Personally I'd go for something like:

DA 15mm f/4 Limited
DA 35mm f/2.4
DA* 50-135mm f/2.8 or DA 70mm f/2.4 Limited depending on range required.

I am thinking of replacing my DA*16-50 workhorse with the DA15 and DA35 due to size and weight. I think the 50-135 is irreplaceable though.

Try and see? Depends on the subject though.

I don't like the in camera sharpening for the K10D, too large a radius, smears fine detail. I'd rather shoot RAW.

If dynamic range is important and preventing cliping then lower contrast is better.

Saturation is a tough one.

I use the Dell 2209WA as it has almost perfect sRGB coverage when calibrated. When sending files for print they come back looking like the screen.

Most photographic printers I have seen use sRGB profiled printers.

£240 is very steep considering a 2nd hand K10D with all accessories and a lens is £250 and a K100D with a lens is £150! On top of that there is no SR in the K110D!
