Buying a Pentax 645Z in 2021

I find it reassuringly expensive feeling. I love the deep handgrip and logical controls. The mass doesn't bother me, but you need a big big bag, a flipside 500 seems really good as it is deep and long, with a large comparyment at the top for the body to fill.

Dumb question - do these old Fuji MF lenses adapt on to the GFX system or even mount on?

Some ICM photography from me - taken in the Bluebell woods in Kinclaven. Others probably do this far better than me. I really enjoyed this but it's not my norm - a tbh a little bit of a waste of a medium format sensor.

Of course - and it is a given that at this level the photographers composition, subject and light as good as it can be.

These aren't beginner chump camera's but tools for highly skilled amateurs or working professionals. Therefore you'd just expect everything else to be good and when I saw the lens sample was like this, well lit, composed, focused, good subject, nice light but with that blurring you couldn't print this image other than a small size - which defeats buying a system/lens combo as expensive as this.

So - at this level -the performance of the equipment is of paramount of importance - because the people that use these camera's will be at the pinnacle of their photography.

So why shoot top level digital medium format - surely an APSC system and kit lens would suffice.

I agree re the shooting wide open part - but having something nice and sharp and not blurry matters to me and my style of work. I wouldn't be in business if it didn't.

There must be QC issues or something to have so much variance. The 23 images I saw were stellar, the lens perfect right into the sides - not a hint of smearing or anything. Wide lenses are often worse for this but this was as good as it got tbh.

Some Woodland stuff. All with the 45-85 and 645z


Whilst I enjoyed exploring this little bit of forest near Loch Chon these style of pictures will never hold the appeal of the big vista style shot, or detail mountain shot. However this was what the weather conditions offered with a thick fog killing the plan for golden light reflections at Loch Ard or Loch Chon.

Probably not the right place for this post but has anyone seen the sample images from the Phase One 150mp.

Pentax have to make a full frame 150mp 645z and release some newer glass. They just actually have to. This is amazing and if they could do the body at 10000 or so I will be first in line to buy it :D

TBH the colours (using DXO as the RAW converter are more neutral). The ones of the Pentax cast red so I always have to bring the red tone curve black point in a little, or the green white point tone curve in a little to line it all up. That's how you neutralise colour, make sure the R, G and B curves start and/or end in the same place as each other. With the GFX 100's they pretty much all did - not seen that with the 645z. Now that might be how DXO decodes the 645z PEFs and an LR user might tell an entirely different tale.


The lens copy I saw was a total turd. A POS of the highest order.


Don't take my word for it
Fujifilm GF 32-64mm F4 R LM WR sample gallery: Digital Photography Review

Image 4/32 - ok wide open but check the smearing. Top right, and left side...yuck.

Image 8/32 - trees RHS...
Image 20/32 - bottom left.

Some might get lucky and get a good copy but I would file this lens under the absolute worst lens I have ever seen performance wise given a) the shape of the sensor b) the price point. This isn't a cheap kit lens at 300, or indeed a super fast zoom with a long focal range. It should be better than this. A lot better.


Now...the 23mm on the otherhand was exquisite. If you want to shoot wide angle it pains me to say this, get a GFX100s and the 23mm. Deeply impressive.

I've just spent the afternoon editing some GFX100's files taken with a 32-64 and 23mm hired by a photographer I know and trust well. You can see the guys work at LongLensPhotography Fine Art Landscape Photography and he is one of the best landscape photographers in the world.


I use DXO photolab 4 - now if you use the lens sharpen tool you have to turn it down from the default options - not so with the GFX100's on with either lens. I posted this on another forum and I will here as it sums up what I thought about the files.

The extra 50mp over the 645z is nice - I thought it would have more detail actually given the jump in MP's - it is there but not to the extent I would have expected. I don't feel short on pixels with the 645z but this is very good indeed. 100mp is the goal here, I can understand the want to move on to 100mp.

The Pluses.

I couldn't see PDAF banding or stripping. I was expecting to be able to see it. This is an non issue. Same will apply to the Sony A7RiV. I've made noise about this in the past. Totally ignore me, non issue - use with confidence. You will absolutely not have this problem with this camera.

No sensor dirt and I could see at least two lens changes with his time with it. None at all. These are very well sealed indeed and vastly superior to any other camera system I've seen in this regard. My Nikons all sucked dirt in, even with the 645z the odd one get through the sealed 28-45 and the other lenses are in the dust sucker category.

Colours and dynamic range. In practice just as good as my 645z. These are nice clean files entirely worthy of a body costing 5500. Is it 1900 better than a 645z. Dunno, the pictures he took were from the Clifton bridge and I don't have a direct comparison to compare it too. But 1900 is not a lot of money these days. There is nothing garish about the colours from the Fuji. If they come out like that it's down to the processing, not the camera.

The 23mm lens was sharp everywhere and will offer a wider field of view over the widest lens in my set up. That lens is good and worthy of its relatively modest price tag. This is a very good lens and offers something that you just cannot get on a 645z system. Whether you would want something that gives a field of view this wide is another matter entirely.

Downers.


The 32-64 is an actual piece of s***. Dreadful at 50mm in the sides - actually unusable and worse than some budget full frame lenses. I would say this is a really lowsy lens. It is not remotely in the same league as the 28-45 from Pentax - not remotely in the same price bracket and it shows. You are better with a lens that costs 5000 that actually is perfect rather than one that costs 2200 which is utterly hopeless. It was not even in the same league as my old Nikon 16-35 which I would rank as pretty lousy. I've now seen two sets of sample images taken with two separate copies to know that this lens is a pile of complete and total crap. I imagine this how crappy lenses like 17-40 L performs. It is a pile of junk made for crap amateurs who have all the gear and no idea.

Hot pixels - there seemed to be a massive number of them in a 60 sec exposure - certainly in the 100's. Even on a 1/25th sec exposure I spotted several. This is a rental camera so it could be shagged from poor use or a feature of having the sensor always on if you are using the EVF - a bit like using live view on a DSLR constantly. That is not something you should do with a DSLR but the number of hot pixels on a 60s exposure was well into the 100's and I spotted 2 on an exposure at 1/25th. I would rank this as concerning but maybe a feature of a used and abused rental camera used by clueless amateurs rather than a seasoned professional who looks after their gear.

I've yet to see 45-100 sample images and 100-200 sample images but thoughts would be just to buy the expensive primes on this system given just how awful the 32-64 is and how good the 23 is.

I won't be defecting anytime soon and never ever if Pentax make a 100mp version of the 645z.

There's bags of contrast here and the first stands out for being very naturally processed.

Advice though - Silver FX can be very destructive and I'd suggest just creating B&Ws without it.

With the last - a simple slide of the saturation slider the other way would have got you there in a spit second. De saturated images can be fun.

I haven't got one - and I would consider one but not without the ability to take a front mounted Lee filter system. The dynamic range of the 645z is good, but not 30 stop good.


28mm on the 645z actually does it but when I shot 35mm format Nikon I found the 20mm F1.8 did the spot the best. It's the only Nikon wide lens that doesn't have smeary sides. Even the fabled 14-24 is a cheap piece of rubbish with soft sides. I hate soft sides. I expect completely uniform sharpness everywhere on the frame - every part of the composition and picture is chosen to be there so it matters, greatly. The 28-45 is the only wide zoom I've ever had that I could trust in this regard.


_DSC3429 - Version 2 by Stephen Taylor, on Flickr

Because of the shape of the sensor - I don't think 25mm would actually do it as the 35mm sensor is 3:2 and not 4:3.


_DSC3430 by Stephen Taylor, on Flickr

It is just a nicer shape of picture - and tbh that was a big motivation to ditch 35mm and move the 645z - the 4:3 shape sensor works better for my tastes now.

I redid this image not long ago and tastes evolve - cropping it 4:3 worked for me. I only wish I had this camera sooner - it really has been by far the best camera system I've ever owned. Combined with DXO PL4 it is unstoppable.

For this shot - you need a still evening and something 28mm or wider. I wouldn't want to do this with the 32-64. The 28-45 is fine, the 23mm would be the one though on your system.

Yes, but rather than walk up the Devils Staircase. Walk down to the river - you can see this spot from the layby and IMHO is far more worthy a spot of camera time than walking up that (I've done both).

This is a well known tripod hole of mine - little different with the 645z due to the 4:3 shape of the sensor and 28mm being as short as it goes - but still managed to fit it all in

Does the Sony A7Riv which shares the same pixel pitch as the GFX100s utlisise this.

No - still the very first one by a country mile. And I am using a calibrated Eizo screen with a colour managed browser. The first one that you think is warm is bang on colour correct.

Richard - the first is much better with more neautral tones. The second post is too green in hue/wb with the whites having a noticible colour cast. The first has the correct colours.

That's what I meant to say - fly back from Edinburgh and down the A82 from Inverness to Crianlarach - follow A84 to Stirling and pick the M9 up to Ediburgh.

Could make a few detours to the Trossachs but they aren't nearly as remarkable as Glencoe/Rannoch Moor.

That's a very good suggestion and the OP could make the trip via rental car to GLA and fly back to EU taking the lens to Glencoe/Rannoch Moor.

I am convinced, now more than ever, that if I never left Glencoe (I live near) I could just make do with 1 645z and 28-45.

Actually, scrub flying back from GLA, fly from Edinburgh making a stop at the Kelpies using the 45-85

I've never had a GFX or mirrorless camera but the 645z nails low light focus - it doesn't have many points but crucially it never misses. That's not always a given with other camera systems. For 2021 this is still the best integrated sensor DSLR money can buy and I'd rather have a 645z than a D850.

To the original poster - I would just buy the lens from Ffordes and pay the import duty. It really is worth having and I wouldn't be without it. Optically it is an actual wonder.

Other point - processing wise I use DXO photolab - it again seems to work very well with the 645z files.

That's one of the big pluses with landscaping in Scotland - lot's of low hanging fruit :D. I am a photographer - not a hiker so prefer to drive and arrive rather than walk for hours (especially with a 645z on my back). I came to landscape photography through a love of driving and road tripping, not from hiking which I derive no pleasure from.


Hopefully I will however be doing just that later in the year when I am back in the Pyrenees. Most of my shots require a degree of legwork. Practically none of mine here do.

Depends on the field of view. Optically I've heard mixed views on the 150-300 but I might pick one up off eBay - saying as they are relatively inexpensive and already have 2 645z's....

---------- Post added 06-01-21 at 07:27 AM ----------



Very meaningful. I really love the big brighter view finder in the 645z. It's a joy to look down.
