Yikes, you mean it is heavier than a film Pentax 6x7? I had one of those with a 45mm WA lens at one time.

Be assured the Pentax 645 is an excellent medium format body. The lenses are excellent also.
I used one for several years and it never let me down. Wedding was part of my use with it. Always excellent negatives that could be enlarged to huge sizes.
Yes, it is a heavy camera, well built and will last for years. The price could not have been any cheaper.
Congratulations and enjoy the new camera.

The Pentax 67 is bigger and heavier than the 645.

Sir! You are to be commended in using the Pentax 6x7. Only the physically stout of heart are able to wield those beasts!

For my atonement, I used to haul around the RB67, even handholding that hunk of iron and glass on occasion.

Today, I'm using a Mamiya 645 Pro TL for 645, and a Mamiya C330s for 6x6.

I got to try out a Pentax 645 a number of years ago, but I liked the Mamiya (Super and Pro) for its flexibility.

Is it possible to get a digital back for that beast??

Recently, and I DO KNOW this a tad off topic, but it is still in the medium format genre, I recently sold my CANON 7D Mark II and one lens, and traded it for a CANON 1V HS in like new condition (from KEH-superb vendor)-35mm film format, as it uses my CANON EF mount lenses, and so forth. It too is a beast and as a 79 year-old with some weaknesses, I often struggle with hauling the beast around, but the film images are worth the effort, especially the FUJI Velvia 50 and Kodak EKTAR 100 images. But I digress!

I also have a Mamiya 645 Pro TL with the auto exposure viewfinder, 45mm f/2.8, 80mm f/2.8 and 150mm f/2.8 Mamiya-Secor lenses, several 120 and 220 film backs/inserts, motorized grip, Metz "potato masher" flash gun, cables, and so forth all of which are in mint condition. Likewise for the FUJI and Kodak imagery!

Sorry for the slightly off-topic comments, but I could not resist the endowsement of the 645 film format.

I have not seen that accessory. However, the 645 comes in several flavors...

Film: the 645 (basic and first model), the 645N, 645NII (both are improvements on the 645 - auto focus, matrix metering, mirror lock up, etc.
Digital: 645D and the 645Z, both of which are wayyy out of my league cost wise :)

I had a mamiya 645 pro and three lenses when i did weddings. You will love. As for weight. My Mac truck and kodak instamatic weighs more 👍

There are adapters to use Pentax 67 and Pentacon 6 lenses on the P-645 also .....(fully manual)

YES!!!!! That's what I mean by a real camera. Congratulations. Now you are approaching "Full Frame" sensor. LOL None of this namby=pamby 35mm.

Instead of developing a digital back for the various Pentax 645 models
Pentax chose to develop a whole new digital camera- the 645Z.

I have 16 lenses for the Pentax 645 system, so I also bought an adaptor
that allows me to use those lenses on my Nikon cameras.

There is also a "shift" adaptor (which I don't own) to attach those lenses to my Nikons.

If I had Pentax 67 lenses, there is a "Tilt and Shift" adaptor available.

If you get tired of taking and developing film, get a fotodiox adapter to use those lenses on your dslr.
