Originally posted by Ryan Tischer Hey all, I've been shooting with the Pentax 645D and then the 645Z since 2012 and have to say I've been pretty pleased.
However, the idea of reducing the overall size and weight by moving to a mirrorless MFD is also tempting. Adding on the fact that Pentax no longer seems serious about pursuing a new version of the 645Z or new 645 digital lenses and with Fuji releasing a new 100mp mirrorless sometime in the future (and supposedly their lenses that resolve well enough to take advantage of the sensor) I'm not really feeling all that loyal to Pentax anymore. Plus, my understanding is that Fuji's customer service is much better than Pentax (I've never had any equipment issues with Pentax, but have heard horror stories of 6+ months to get a sensor or lens repaired). I shoot landscapes and often print very large (I've sold a number of 8'+ wide prints), so the 100mp sensor would actually make sense for me, especially if I decide I need to crop something or am in a situation where using my pano head isn't an option.
So, some questions for anyone that may know...
Can the Pentax 645 lenses be adapted to work on the Fuji mount? I love my 28-45mm, plus have ten other Pentax MF lenses for that system. The Fuji lens line up is more lacking than Pentax, which is also something that may hold me back, but if the lenses could be adapted that opens up more options.
Or, could the Fuji 23mm be adapted to work on my 645Z? I often find my 25mm to not quite wide enough, plus it isn't as sharp as the 28-45mm.
Also, has anyone done a comparison between the 645Z and new mirrorless Fuji MF cameras?
I use both so i might be able to weigh in. They are both nice systems. The fuji is putting the effort that i wish pentax would into their system. I initially bought the gfx because of that very fact. I wasnt getting the updated sealed lenses that i wanted. With the fuji system, the lenses are very sharp, i love the ability to control everything on camera, i love the extended iso to 50, i like how there is reassurance that they are making an effort with the system (new lenses, capture 1, third party support in form of lenses, etc), evf soom in to get great autofocus for manual lenses,i love how compact and light the system is( it is the size of a k1 maybe even a little smaller), and no mirror vibration.
In the GFX laowa is coming out with a 17 mm lens for the system, you can adapt 35mm lenses such as the tiltshifts, you can use canon lenses with the camera with full autofocus. Even the film simulators are nice for those moments you need a jpeg file. Oh and comparison to the pentax, it doesnt have more of a magenta color to the files. I like how the gfx has a quick menu which you can customize for main settings.
As far as 645z goes, it has much better raw files, and you can use dng. Although the fuji you can shoot compressed, the file sizes are massive,111 with fuji compared to ~70 with the z. Although i want sealing with my lenses, i prefer the softer nature of pentax lenses which ill tend to adapt on to the gfx(unfortunately no autofocus). Another nice thing is how there is a bottom and side mount to the z. I like how there is no delay when looking through the ovf of the pentax, more telephoto lenses for now, weather sealing on body is great(havent tested the fuji quite yet), the files are more smoother and i like how they arent as contrasty(i needed to reduce it on the gfx), menu system is also nicer on the 645z. Unlike the gfx, i findchanging between different modes easier to navigate the z.
When i get home ill make sure i share a few files between the two cameras.
