I certainly can't speak to your personal situation, but in the US, purchasing a 5-7 year old MacPro on the used market and upgrading it with a 4-6 gig nVidia card and memory is about $1700. That's considerably less than a new 27" iMac with I7 processors. And Apple still sells a lot of iMacs loaded with 4K iMovie software. Even Fotomagico, $100+ slide/video show software, allows editing and outputting in 4K. My single core 2012 MBPro with 8 gigs of memory handles it with no problem.

Resistance to 4K from entrenched 720/1080 shooters reminds me of broadcasters in the US who, at first, years ago refused to transition to HD, claiming 480P SD was good enough.

Your mileage may vary, as the saying goes. My observations have been using primes for comparisons, grading in post, not in the cams, and editing on a 30" 2.5K display and 55" 4K display. The differences were dramatic enough for me that I would never place a K1 1080 clip adjacent to a GH4 1080 clip, much less a 4K clip.

And FWIW, a workstation costing thousands of dollars is not necessary to edit 4K footage effectively. My 2012 vintage Mac Pro with 24 gigs of memory with an upgraded nVidia video card with Cuda drivers and Premiere Pro, works just fine.

The GH4 offers menu selection of CODECS ranging from highly compressed to very high bit rate for 1080. The K1 uses a low bit rate for video. As has been mentioned numerous times, and it applies to any camera capable of shooting in 4K, the best option is to shoot in 4K and scale down to 1080. This offers better quality than shooting natively in 1080.

Actually, you can easily tell the difference between the video quality of the K1 vs a GH4/5 or any of the newer SONY models. The K1 video is better, in my opinion, than some of the earlier Canons, but it's no match for the current state of the art, regardless of videography skills. Actual resolution of 1080 footage out of the K1 doesn't come close to what 1080 can deliver. It's adequate for home movies, talking head YouTube presentations but in my opinion it's somewhere between standard definition and 720P in terms of actual resolution.

K-1 or 645D? I did it (not the sensible choice)
Posted By CDW

If you're shooting style doesn't require the use of high ISO over 800-1600, I would say the 28-45mm is the lens of choice vs the 35mm A (which I own). My 35mm seems quite prone to flare whereas I noticed far less when I once used the 28-45. The 35 is also less contrasty than the 28-45. The sensor in the Z will allow you to extract more shadow detail but the difference isn't nearly as extreme as the comparison between SONY and Canon sensors in this respect. If it were me, I'd keep the setup you have. The ten megapixel difference in sensor size is almost meaningless unless you're displaying ultra large prints aimed at the pixel peeper crowd.

I owned the 645D, now the Z, and I look back at the RAW files from the D and in my opinion they hold up against almost anything currently available, when used below ISO 800. I've shot wildlife, handheld, with the D at ISO1600 in Zion National Park and the results were excellent. The colors do have a look that are hard to duplicate with the Z. This same opinion is shared with a couple of other photographers I know who have also owned both bodies.

Over the last 30 years I've shot 4x5 large format, 6x7 and 645 MF film, APS-C digital bodies and now m4/3, FF K1 and 645Z MF digital. My personal feeling is unless you're shooting film for the love of it, the slower pace, etc., the K1, especially in the pixel shift mode or the 645Z, will easily match or beat most color film stocks shot 645 film format. You'll need high quality drum scans or at the very least scans from an Imacon or equivalent, to come near the resolution of the digital sensors. Scans from flatbed scanners, in my opinion, will not best the files from the K1, much less the 645z. Film scan issues also open up other issues, such as flatness of the film when scanning, the time you'll spend cloaning out dust specs, etc. Film will dramatically slow your pace from capture to post and certainly has the ability to drain your bank account.

Mirrorless 4k video option for Pentax lenses
Posted By CDW

Yes, manual focus with an aperture ring. Even an ordinary lens, in terms of optical performance, is usually sharp in the center area. When used on a m4/3 body, the image is almost always uniformly sharp from edge to edge. The down side of course, is that focal distance doubles when a FF lens is used on a m4/3 body -- 35mm effectively becomes 70mm, etc.

Ditto what sqrrl posted. The GH4 is currently the best value going in a small, mirrorless design that delivers exemplary 4K, excellent stills and nails focus virtually 100% of the time. It's the backup for my K1. I use it with an Olympus 9-18 (18-36 FF equiv.) and often use some of my legacy Pentax glass with a K to m4/3 adapter. I find myself frequently leaving the K1 at home.

Looking for a Large Format Printer or Plotter. Suggestions?!
Posted By CDW

I've used large format fine art/photographic printers for over ten years--Canon along with one ill-advised excursion with an HP. If most of your work is cartographic, I doubt you'll be interested in a large format printer especially designed for art/gallery quality printing needs. I'm not aware of any model that will automatically switch between two rolls. Photographic quality printers will yield far better image quality for art reproduction vs plotters. Most photo/fine art printers utilize 10-12 color print systems, have wider color gamut, accept 16 bit files and have profiles for a wide variety of branded and generic paper types, including canvas. I think your goals may not be easily reconciled.

Ditto what DeadJohn said. I just completed three weeks in Western/Northern Australia. I took the 28-105, a Tamron cheapie 70-300 and 14mm Rokinon, plus ND and polarizers. I had no need for anything else, at least for my style of shooting. The vast majority of my shots were captured with the 28-105.

K1 Video is not that bad
Posted By CDW

The K1 is certainly capable of delivering video that is more than acceptable to many people. I certainly see a lot of cell phone video, shot vertically instead of horizontally, that is poor quality when viewed on a conventional large screen set, and inferior to K1 video. I also find the K1 video superior to video clips I shot years ago when I owned a 5Dmk2, and everybody was raving about its video quality at the time. However, SONY and Panasonic have advanced the performance levels of HD and UHD in consumer and prosumer camera bodies beyond anything Canon, Nikon, much less Pentax, are delivering at this point. If I want to shoot video I use my GH4 simply because my K1 won't even come close.

I have no idea, but that wasn't your original question. I answered it.

It's likely the pro Canon shooter was using the Canon lens because it met his needs and Canon Professional Services has its act together in supporting professional photographers, as opposed to Ricoh, Olympus or Panasonic.

I print to sell images ranging from large panoramas on canvas to fine art papers in smaller sizes. My printers include a Canon ipf8400, Canon Pro-100 and and Epson 3880. I'm a bit jaded at this point in my senior years, shooting images and locations that I feel are worthwhile commercially or those that I have on my bucket list.

I never got into chemical darkrooms. Color and Cibachromes were my choice years ago vs black and white and the smell of chemicals. With digital I've come to enjoy post processing and creating slide shows with a mix of music, still images and video.

If Elvis rose from the dead and showed up at my local Shell station at 3:am to fill his Cadillac, and I had to use ISO 25000 to get the shot, it would still be worth a million bucks.

I regularly use up to 6400 for nightscapes, night sky.

K-1 and its filming future?
Posted By CDW

This discussion seems to come up about once a week. And the answer remains the same. If you want to create serious video, especially in 4K, you go to Panasonic or SONY. The DSLRs of Canon, Nikon and especially Pentax are also rans. The bar has been raised with 4K, especially when shooting in 4K to utilize image stabilization in software, panning/cropping, and then down converting to 1080P. As an example, the Panasonic GH5 delivers almost the max of 1080 lines of resolution in 1080P and over 1800 lines in 4K (2160). Nikon, Canon, Pentax, don't even come close.

Part of the problem is indeed the sensor. It was decent as SONY implemented it in their A7r but is not satisfactory for 4K. Perhaps Ricoh will realize at some point they are losing thousands of potential sales because of lack of decent video, lack of contemporary lens and lack of proper service facilities in many parts of the world.

All that said, the K1 is wonderful for landscape and night sky shooters.

Canon is now behind the video curve, with the exception of the 5DIV. Canon seems to purposely handicap their DSLRs in terms of video capability so as to not steal sales from the pro video camera sales.[COLOR="Silver"]

Pentax K-1 laughing about Canon 6DII image quality performance

I would guess that the majority of Pentax owners shoot landscapes, nature or travel vs portraiture and weddings. I think that has been true from Pentax medium format film days. The fact is, unless the contrast in a scene is extreme, with almost five stops of shadow push available with SONY FF and MF sensors, it's pretty easy to eliminate the need for split density filters, which are almost always visually obvious in their use. Post skills are not that difficult to learn and implement efficiently.

As for Canon, as much as I love their printers and customer service, it's pretty laughable that most of their entry and mid level systems have dynamic range no better than Olympus or Panasonic m4/3s bodies, not to mention being left in the dust by Pentax, Nikon and SONY.

I own both and there are some instances in which the K1, shooting with PS, delivers perceivably sharper looking images, especially if moire patterns are an issue. PS pretty much eliminates moire, which is certainly an issue with the Canon 50 meg FF bodies.

From my standpoint as a landscape shooter, I'm far less enamored (make that envious) of the Canon lens lineup vs Pentax. From my Canon 5D2/L lens days, I feel the Pentax15-30 is the equal of the Canon equivalents, likewise the Pentax 28-105, while not as wide, easily matches the Canon 24-105L, and Canon's 70-200mm F4, one of the sharpest zooms in their lineup, is more than matched by the Pentax 60-250, in spite of the fact it is supposedly an APS-c design. When legacy primes are added to the mix, what is lacking for a Pentax landscape shooter? And if you're a night sky, astro shooter, Canon has nothing that really matches the features of the K1 for that application.

As for video, all DSLRs pretty much suck when compared against the current state of the art. Panasonic and SONY rule in that area.
