ISO 100. Can’t locate one at the moment but if all else fails I’ll just have to wait until one becomes available. White balance was achieved by using the eye dropper tool on the same location for all cameras, but the 645Z came the closest to getting it right. user guides, manuals), as well as related accessories, can be found on the official Nikon and Pentax websites. 4.61 in. 19/21/25mm: yes, I think it’s partially down to the format, and partially down to the geometric projection; I assume this has something to do with both lens design and focal length, which is why some wides appear wider than others (stretching at edges). Both the equivalent models (44′, 12 inks) from the other two big companies?? Not for a technical/pixel peeping film vs digital comparison, but a subjective, visceral one. And the D800/810 is certainly better at a pixel level than the last generation of medium format. For ultra wide angle prime lens, the Pentax smc DA 25mm f/4 AL (IF) SDM AW lens is the best choice. About two hours in the chair at the hospital, I think. These seems to be no obvious place you can find them…thanks! That coupled with the increasing numbers of rude, abusive and demanding email I’ve been getting start to wear you down after a while. I felt myself thinking that as I was reading. I must say I love your style of processing images. I’m just about to get a 645z and I have a question that I can’t seem to find any answer to on the net. I think there are two deciding factors here: firstly, whether you’re going to use it in studio or with available light, and secondly, the rendering. The difference is further compounded by the fact that the two CMOS cameras had more dynamic range to begin with. The only one you can buy new is the $18000 US CFV-50. The Pentax 645Z was announced more than two years ago, back in April of 2014. I would imagine your travel pack with 645Z, back-up camera, and other items, comprises some considerable weight and bulk. Between Ferraris, bikes and several rather nice cameras you successfully took my mind off feeling old for as long as it took to read a few thousand words…, Todd likes your comment: Great article, i’m planning on getting the 645z, to use with my older 67 lenses. […], […] least it is a bit of a toss up depending (can't separate noise from sharpness). I’d spend more on lighting and tripod/support than the rest because it will make the biggest difference here…. Its actual ISO seems to be about 2/3 stop less sensitive than the others despite having the same numerical rating – important when taking into account flash and other exposure calculations. Ming The… I would say that there are actually very few lenses indeed that can be used on digital without […], […] Phantastic review made by Ming Thein, lengthy and full of interesting pictures. Review summary. There’s plenty of film work from my Hasselblad here. I did read it on the same way I read the passionate chronicles of the chess world championship matches; I don’t understand very much but I like them : ). Remember it was designed for film, not high density modern digital sensors…. Eduardo, Thanks Eduardo. Think of this as a continuation of my initial three part review, here, here and […], […] Choices, choices, choices. This actually reminds me of a related question I’ve been meaning to ask – when setting up a colour profile, do you have a standard colour chart that you use? Ming, in this day and age of advanced CMOS I’m still a bit of a sucker for the V. So, thank you for this comparison. In reference to your statement “Even though the Pentax is actually wider at an equivalent 19mm horizontal field of view, it doesn’t feel as wide as the Zeiss (21mm on regular 35mm)” Does this have something to do with how aspect ratios of different formats are perceived? Thanks. All cameras were shot raw and processed through ACR CS5.5, because this is what I normally use in my workflow. Leica S … Always like seeing them (and like reading stuff on your blog). You could try a LF lens on a bellows (or Cambo thingy), which would be much easier to trigger/control since they’re designed to work independently of the camera backs anyway. I’d say the 645Z’s higher 25k and 51k sensitivities can be used if you don’t mind downsizing. “… aware that some subjects really don’t gain anything with more pixels in detail reproduction … ” That part of it. The difference is seen mostly at normal angles of view and below: it’s difficult to describe exactly, but wides look wide. Unfortunately, I can only agree with you – and I’d be right beside you at those very gates…!! I’ll break down the assessment into a few categories. Dear Ming, What great reviews, thank you. best, Andrea. all out) – and that’s perhaps not so sustainable…. How is that productive? 4:3 for me feels best in portrait mode, especially for moderate wides and normals. Love Nikon, hate only their conservationism, lack of standards (no built in wifi, gps) and innovations….but it seems Canikon still doesnt have to be innovative….still…tso fuji, oly, ricoh/pentax and espc. inside the V-P645 adaptor’s volume. While the latter is top notch, I, and no doubt many of your discerning regulars, am particularly drawn by the calibre of your insights (for as long as you care to share them & not go spare with the pressure). *brrrrr* Speedy recovery! If even they recognise Mr Ming Thein’s talent, it should serve as a green light for conservative Japanese fellows). The bigger sensor size; the fact it fits in with a film camera system; the pleasing tones (great point about resolution versus tones as we get more sampling). Thanks! so i was back on the 645z agian… but now… i don’t know any more. Nope, unfortunately it won’t. As for me, I find your non-consumerist passion & measured comments absolutely refreshing. She’s getting better, but slowly…. ‘m planning on getting the Nikon 24-70mm VR if/when it comes out. Further information on the two cameras (e.g. PENTAX 645Z + smc PENTAX-FA645 45-85mm F4.5 @ 45mm, ISO 100, 1/15, f/11.0 Overview and Sensor Size Comparison. He only problem is that by that time, everybody else in the industry will have moved on again…and a Leica will probably cost $100,000 or something. Keep in mind that scanning is a bit of an art to itself, at it takes some work to get the best results out of scanning. The old-fashioned guys dealing with their customer base the old-fashioned way (e.g. Pentax 645: D-FA 25/4 SDM, D-FA 55/2.8 SDM, D-FA 90/2.8 SR SDM Macro – and perhaps the FA 200/4 if focused manually with live view. But having said that, all else being equal, you do have the ability to extend that ability to make stunning prints far further with newer hardware. The Pentax 645Z Medium Format DSLR is a medium format crossover camera and update to the popular Pentax 645D.Key features include: 51.4MP CMOS sensor. That can be a good and a bad thing – good because you’ve got a lot more room for external controls, bad because it means even more weight. How true! No access to a Coastal 60 sadly. In the tropics, or in any kind of bright sunshine, that means using ND filters (focusing becomes tricky), having almost no depth of field control and running into diffraction issues, or overexposure. Agreed on the D800E/810, which is why I have two of the former as my workhorses. The Samyang is clearly even worse, but has the one advantage of independently rotatable TS axes. The model retains the same physical size medium-format sensor but ups the … Those lenses allied to a state of the art EVF, incorporating 81 autofocus points across the entire sensor, in an altogether lighter and easier to use package, particularly for those of advancing years and rampant presbyopia..!! Perhaps less so with C-41, even in medium format, and perhaps a bit more so with B/W films. If so what equivalent lens(es) would you suggest? Sorry to hear of the dengue fever. I stopped at 3200 – this is probably about the limit for what I’d consider very good quality after some noise reduction/ cleanup; 25k was thrown in for kicks and entertainment. Thanks Andre. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. feel much the same as the D800E: effectively instant. On the other hand: life moves on. This is an important point to note: all of these sensors are relatively high density and will test lenses to their limits, especially the D800E; a lack of good lenses is its achilles’ heel. I would be your your location guide. My real reason for commenting, however, was to wish you and your wife well – Dengue Fever can be extremely nasty. Haven’t tried anything longer than the 200/4, but even at 200mm you really need a tripod for precision – even if you have ample shutter speed to avoid shake. 4.61 in. Add products. “Happy Birthday Todd! This isn’t quite the case with the CMOS cameras, which only start to visibly lose dynamic range over about ISO 800 (D800E) or 1600 (645Z). You can get a used 645D for circa 250,000 JPY… After reading your review, I’d say the 645D is dead in the water as a used choice and only of novelty value for the Kodak CCD, or as a make-do until used 645Zs begin to appear in a few years (in the meantime build a lens arsenal on the 645D, etc). I think it’s no surprise here that the two newer cameras have the largest shooting envelope of all; I’d put the D800E and 645Z on par because what the latter gains in high ISO performance and resolution it gives up to faster lenses and a more flexible system to the former. The amount of work it takes to maintain this site plus everything else is physically impossible to sustain on a long term basis – 16-18 hour days, every day, is normal. Pentax 645D was introduced to market in March 2010 and Pentax 645Z was launched in April 2014. It would be interesting to see how it performs, which I think would be way better than the Kodak sensor they are currently using in the S but not as good as Sony’s sensor. BTW, my website search was for a simple Pentax 645D vs 645Z comparison–much more was gleaned and I appreciate that . Thanks for the color info: I’m glad my monitor wasn’t going crazy! Popular Pentax 645AF2 Mount Lenses for 645D and 645Z. Shooting envelope Everything other than the ISO test series was shot at base ISO (100 for all cameras) on a heavy. I’m a landscape photographer and I still use films (MF and GF) but now I’m thinking to buy a digital camera that lets me do also quite big prints. Which leaves a niggle in the minds of many photogs I’m sure, so I think we’ll see a ton of people uhming and ahhing over the Z versus the new 810. As a consequence it will allow the 645z to be used at a higher sync speed (not sure of the limit yet) without banding. And that’s not quite the case, because this camera is about a stop or so cleaner at the pixel level, too. Thanks, There’s a possibility you might lose some power if you use the high speed solution. I wish you made solely the samples for the D810 campaign…..the samples arent that much exciting/appropriate imo…;), Further i would love to see you in “digitalrevs series pro photographer cheap camera”..,,would be a funny challenge for you…. For ex: http://www.senthilwildlifephotos.com/#!/portfolio/G0000cMvK4Yjlsgw/I0000tIXi8vSL6ls. The 645D and Z sensors are bigger than “full frame” but markedly smaller than the real-deal film 645 aspect. Another similarity between these two cameras is that both Pentax 645Z and Pentax 645D sensors lack anti-alias (Low-Pass) filters. So far I’ve been using a Fuji X-Pro for most stuff (casual/workshop shots, in progress reports etc) and borrowing a friends Nikon D3 for finished jobs/more pro-looking shots. And finally, the CFV combination is really a scalpel: it excels at some things, but definitely isn’t for every situation. Personal preference. Battery life is also noticeably better, and despite the increase in pixel count, the camera seems to be no more susceptible to shutter vibration than the old one; I presume we have a new mirror and shutter mechanism to thank for this. film 645s are portrait because of the way 120 film is wound. hmmm… I think your processing is elegantly less saturated, with a deeply restrained grade, yet sweet and aromatic, yielding delectable smoothness, a rich earthy flavor, a profusion of virtual aroma, prolonging the pleasure with its characteristic slightly neutral finish and velvety structured notes. I’ve already explained the rationale for using the lenses I did. I can make medium format digital pay off for me, at that level the ROI is much lower than I’d like – and that’s before we even count the cost of adding lenses. However, this system as a digital option has one enormous catch: because the film capture area was meant to be square, the viewfinder and controls were laid out in such a way as to only work in one orientation. Now the real comparison would be between those in your review and the rumoured new S with a 50mp CMOS sensor and wouldn’t it be good if Leica abandoned the baggage of history and turned the S into a giant Olympus E-M1? Pentax 645D vs Pentax 645Z: Physical Specs and Body features Comparison Size and weight is a big decision factor when you are trying to find the ideal camera for your needs. Pentax 645D. The Pentax 645D is a digital single-lens reflex camera introduced in 2010. My biggest problem would be very blotchy noise in blue skies especially in the darker corners due to vignetting. In a way, this review reads like a peek into your personal process of finding and testing a camera for your own use, and we got to go along for the ride, so thank you! Plus, if your edge transition happens over 1-2px as opposed to 3-4px, then you’ve got less spatial distance for gradation; this is something film does well because it has no finite borders for each ‘sensing area’. A CVF may be one of those tools that are never seen again, so letting it go would surely mean a permanent goodbye. Full HD 1080 60i/30p/24p video capture. Do not need high pixel density, sufficient for a 30 Mpx after resampling. Bottom line though: to see a consistent difference, you’re really going to have to be employing optimum shot discipline all of the time; otherwise that 20% is going to disappear very fast indeed. Although I don’t own one, I feel a greater affection to my manual, analogue cameras than to any modern digital one. It is approximately the same size and shape as the earlier film models, and the lens mount accepts older manual and auto-focus lenses.

[…], […] and new and thus give Nikon a good profit. But will such an adapter actually work the leaf shutter in a V lens (I’m guessing not). I recommend going by what I say, not so much what you see in the web jpegs. I haven’t checked post 645Z release (it was only last Friday! ISO 800. Is the 645Z’s upright position portrait or landscape? Pentax 645D vs Pentax 645Z. . The Pentax 645Z is a medium format crossover camera and update to the popular Pentax 645D. Microcontrast and color rendition are better, and the output simply appears to have more ‘punch’ without being harsh. Though punters’d be a bit mad to pay it, honestly… Even 250K for a used one (which are typically 20,000+ shutters in) is bad value considering what you’ve shown us here. But it seems to me the D700 requires less tweaking than the D800E. I have 20+ lenses from the Pentax 645/67 system and so am somewhat locked into Pentax. Midtone dynamic range, ISO 800 – you can see the two CCD cameras starting to struggle with both noise and shadows crushing; the tonal response is starting to become a bit weaker, too. On tonality, while many may disagree with this view, that is one of the reason I still use film for some projects. However, it seems that Photoshop does not recognize the lens profile automatically. , That’s because I do. But these things are not important to me. Another important factor is the availability of image stabilization. thank you very much Ming. In this section, We are going to illustrate Pentax 645D and Pentax 645Z side-by-side from the front, back and top in their relative dimensions. From this comparison it really looks like D800E, or the new D810, actually is very, very close to 645Z and that makes me think really hard if it wouldn’t make more sense (for my needs) to go rather that direction than to 645Z (and to replace my Hassy + Leaf back) and for proper medium format just shoot on film and good old square. I doubt for instance MF digital can shrink much beyond the Mamiya 6/7 cameras, and even then, we’d need to go over to CDAF and EVFs for precise framing/ focus. Much more interesting would be lists like this: Review: The Pentax 645Z, part II: compared to the 645D, Nikon D800E and Hasselblad CFV-39 ? I had wondered a while back if you were sticking to your 28mm and above because the UWA lenses couldn’t give you corner to corner consistency. Ideally, I’d have liked to have picked the best lens for each system – the 55 or 90mms for Pentax; 45 or 85mm PCEs or the Zeiss Otus or 135mm APO for the Nikon, and the 50 Distagon or 120 Macro for the Hasselblad. As far as I know only the P67 LS lenses work natively/easily. If you enjoyed the content, please consider, All images and content copyright Ming Thein 2014+.
