Originally posted by TDvN57 My suggestion is to rent a 645z for a week or two. There are a couple of posts on this forum where people asked for suggested settings to get going on the 645z, use those suggestions and use the camera for a week or two.
Going to Fuji 50mpx will essentially give you the same "old beast" because they use the same sensor. The Fuji 100mpx is a different story.
Buying an expensive system on recommendations only seems like skating on thin ice in an unknown area.
Regarding flash systems, you may also consider switching to video lights, which will probably cost a fraction of what a strobe/flash system costs, with many added benefits.
Hope this helps.
Thanks Theuns. The renting option would be great if I could get it to work in the UK. It's expensive to rent the 645Z, but then getting these two lenses rented too is nigh on impossible, sadly.

I find that for still life in particular I end up cropping and this reduces the useful pixel count. 4x5 aspect ratio is often where abouts I end up.
I also would like to get a little more DR when I find I haven't got my lights as I want. The 645z would be more forgiving.

Another question, please.
Googling I've found several comments about sensor cleaning being more problematic than, say, the K-1. I've cleaned my K-1 sensors occasionally with no problems (O-ICK1 and Visible Dust tools). Are there any particular issues with the larger 645Z sensor?

Originally posted by marco_gea 1) No idea how it compares to the K-1, but taken on its own, I find the AF of the 645Z (single point, not using the centre point as you specified) just fine for portraits, also specifically when using the FA120Macro (I suggest making use of the focus range limiter switch on the lens).
2) I have those two lenses and I would describe the FA120Macro as superb and the FA75 as very good. I don't have the "FF" K-mount lenses that you mention so I can't say anything in that regard.
3) I actually went the opposite way, from a Fuji GFX50R to the Pentax 645Z. Same sensor. But the Pentax gives me vastly improved ergonomics and is just so much more enjoyable to use (VERY subjective!!). On a more objective note, the 645Z's build quality is superior to the GFX's (but the latter is also absolutely fine).

Thanks Marco. I've seen a few go from Fuji to Pentax. I'm so accustomed with the Pentax ergonomics that staying with the brand feels sensible.
Thanks for the 120/75 comments. I knew it would be hard to pull out comparisons with the K lenses, but as I don't have any rental options comments here can help. These two lenses do seem to be well received for the price.
I've just realised that the 645Z does not have SR on many lenses. This is probably not an issue using 100% flash, unless I need to mix in ambient, I suppose. Made me think a little on how I have become to expect SR on my other cameras ...
