    Hasselblad CFV-50c live view

    Thought I'd start a new thread to discuss this, as didn't want to move the older ones off track...

    At Photokina, Hasselblad announced a firmware upgrade to enable live view on the back. A few people that saw it being demoed in the flesh (I can't remember who it was, sorry,) indicated that while not "great" it would be adequate for focusing on technical cameras. I think the refresh rate has been stated at between 10 and 12 fps. I'm wondering about things like lag, both in terms of general responsiveness and exposure?

    I'd like to know if anyone has anything to add to the above information, or if anyone can describe how it performed in more detail? With Guy's Credo50 review using a tech cam, it's clear that this back is very good value for money if one can live with the documented limitations of movements. It's wayyyyy cheaper than the Phase and Leaf offerings, which I guess offer the gold standard for DMF live view at the moment.

    All thoughts welcome...

    Thanks,

    TJV

    No one seen or heard anything?
    I was sent some samples taken using the CFV-50c and a range of lenses on a Linhof Techno and the results look great. Just wanting to hear about the performance of the on back live view, because if it's responsive and easy to work with, this back seems like a good option. Only problem is the crop sensor and needing the 32HR to give me my widest FOV... That lens is a mammoth!

    Re: Hasselblad CFV-50c live view

    Just checked on the Hasselblad web site, the firmware with live view has not yet been released. So I guess there's some more waiting to do :-\

    The CFV-50c is just fantastic value, I really do hope it works out.

    Re: Hasselblad CFV-50c live view

    I just noted Linhof Studio together with Hasselblad is just now starting offering package deals with the CFV-50c plus tech body plus 40mm Digaron-W lens. Interesting indeed.

    With the Techno the deal is at £15k / $25k. Tech cam systems have never been cheaper :-). Body and lens is $11k so it's still not the Japanese pricing on the back though :-/

    Anyway the kit is sold without sliding back so I assume they believe in the usefulness of its liveview

    Yeah, but Linhof have also released a stitching adaptor for live view backs that doesn't add any width to the camera – obviously because it doesn't have a GG.

    Really thinking that this CFV-50c is the way for me to go...

    Actually, the Linhof & Studio package deals seem very cheap...
    I'm going to send them an email to see what they're offering the back alone for, if they offer it...

    I've asked Paula at Linhof & Studio to record a video of the CFV-50c live view in action when she attends the expo, which she said se'll attempt to do. She also returned with some sharp quotes for a back and accessories package. Fingers crossed this pans out as a good way for me to join the DMF club...

    Great couple of videos via Linhof & Studio of the CFV-50c live view in action. Seems plenty good enough for critical focus, especially considering the challenging light they're under.

    Great stuff!

    Great stuff indeed - in particular, really nice when combined with the Techno (or any other bellows design) - looks like a perfect combination.

    And this back is available new for under $10k (in Japan). Wow. I was holding out for a used IQ180, but to be honest the live view, high ISO performance and low (in relative terms) cost of this back moves it to the top of my Christmas list.

    Anyone going to Japan?

    I'd be interested in knowing what the real prices in Europe / US are. I find it difficult to believe, that you need to travel to Japan to get a Swedish back cheaper. But you never know...

    Maybe mail-order is also a possibility? Not sure if anyone checked with the seller in Japan...

    My bad - it's available at Map Camera for ¥970,000 ~ $8500 US, including sales tax. Without, it is ¥898,149 or $7800 US !!!!

    Ive search and I have yet to read about anyone buying a CFV-50c at that price. How about one of you guys pull the trigger? Anyone got $8-9k to gamble? Be cool to hear how it turns out.

    One thing though, was it the Pentax 645D that had Japanese only menus when bought in Japan? What would the chances of Hasselblad limiting the menu language to limit overseas buyers?

    Would have been nice - but with true live view, all the benefits of a CMOS sensor plus a decent screen I don't think there's the same appeal to tether to a tablet in the field as, say, with the IQ backs.

    If you want some USB3 ports, with the $20k saved over the Credo 50 / IQ150 you could buy a fully maxed-out MacPro, plus a top of the line NEC monitor, and still have a few thousand bucks left to spend on beer *hiccup* ('scuse me).

    Re: Hasselblad CFV-50c live view

    The difference is that no matter the quality of the screen, CCD or CMOS sensor, or quality of the Live View option---you are still limited by the paltry ~3 inch real estate of the screen. I think it's a safe bet to say the majority of end-users of $$$ MFDBs are middle-aged+, and that means aging eyes.

    Tethering to a super tablet like a Surface Pro, besides a bigger screen for aging eyes, brings a lot of different options to the table, not to mention a much easier form factor to use in the field. The point being is that a USB3 card/protocol is more attractive offering more flexible options/usage and probably would not have cost much different at all in final production versus Firewire, a dying protocol destined for the graveyard in the near future, imho.

    For the $10-20K saved (ha ha), you can bet that money is instead spent elsewhere in Dante's plentiful offerings in medium format digital.... But wow---what a nice MFDB offering! If it had USB3, it would be that much closer to a home-run.

    Seriously, Japan is a great place to visit...

    Re: Hasselblad CFV-50c live view

    Don't forget folks that the yen is taking a pounding these days so this also is a factor in the pricing. Now I'm told that with the devaluation going on and the increase in taxes that business is 'soft' so that may also help.

    I was impressed with the live view videos.

    Hmm, next year ...

    I bought my 645D in Japan. English menus are in it.

    But on the bright side, even if the Hasselblad back only has Japanese menus, you will have some money left over for language lessons.

    Re: Hasselblad CFV-50c live view

    I watched the videos of the live view and and it looks pretty impressive. Maybe, soon enough, someone will compare it to one of the Phase/Leaf backs but what I saw was certainly good enough.... It still, though, would not be for me but I can see that it would be very tempting for many.

    I agree with you about aging eyes (presbyopia), but honestly just being able to focus on a specific point via LV should be enough for a lot of us (similar to loupe on ground glass). Having a larger screen for composition (?) is not a necessity for me. I find carrying extra gear to be much more of a hassle.

    Re: Hasselblad CFV-50c live view

    My dream is that the live view and screen quality would be good enough to dispense with the need for a sliding back in the field. I don't mind using some kind of hood to shade the screen, but I'd prefer not to put up with the extra bulk of a sliding back. With that dream realised (I hope, although with some trade off on possible movements,) my Techno stays very close to the size I'm used to and the workflow consistent with how I work now. Good stuff... But... I still worry about the movements... Nothing beats testing for ones self, and that option where I live is very difficult to arrange.

    Re: Hasselblad CFV-50c live view

    Just had a look at the videos for the first time. It looks great! It's a bit slow refresh rate in dark conditions, but still perfectly usable, there seems to be no significant lag which is the important thing.

    I use the Aptus 75 which has the worst screen ever considering visibility in daylight, but still I almost never need to shade it more than with my hand, so I would not worry about screen visibility. Shooting in midday full sun is not a very common shooting condition for me though.

    I would not consider paying $20k or so more for a Phase product to get a little bit better screen and faster refresh rate. To me it's all about image quality and then the rest (screen etc) just needs to be good enough to be usable in the field. It seems to me that the CFV-50c passes that with a wide margin.

    The next question I have is image quality and Phocus workflow, I haven't hard that good things about Phocus LCC correction, on the other hand I don't think the Sony CMOS requires as advanced LCC correction as the Dalsa CCDs, as the CMOS lack tiling and microlens ripple, so if Phocus LCC correction is just decent it should be good enough to handle the CFV-50c.

    I'm still a Schneider wide guy so this is not for me, but I'm still very excited about this offer, it opens up for view camera revitalization and much more affordable technical camera solutions making it reachable for many more users which I think is a great thing.

    I've heard that most of the main Japanese HB dealers have already pre-sold their inventory and are back-ordered (no pun intended). Hoping that B&H may have some grey imports in due course, but if not has anyone got any good leads? Given the excitement and demand surrounding this back, you gotta wonder what bright spark at P1/Leaf didn't decide to pitch something at this price-point (even if it was only in V-fitting)? That said, maybe they don't need the money

    I've enquired via a friend in Japan and there is at least a two month waiting list at Map Camera. I'm a little confused as to why it's much more expensive everywhere else in the world? Perhaps a loss leading, brand building exercise?

    Hi,

    Just to make clear. Seller is in Russian Federation, that is not EU. It may play a role for EU buyers.

    Well, with Putin, you never know, but last time I checked I have not seen a Russian tank parked in front of my apartment…

    Best regards

    From what I've seen in samples I've been sent, it seems to work very well – at least with the CFV-50 and 50c. Have not had a chance to shoot my own tests though.
    Nick, what back are you currently using?

    Re: Hasselblad CFV-50c live view

    trying to sum up a few details, re, the CFV50: please correct any mistakes:

    1. battery is external, available in small and large, hangs below the back (not shown in the product shots i have seen) and will interfere with the SWC unless an extension plate is fitted.
    2. back is only capable of fitting in normal landscape position, battery down. meaning the Aptus rear standard, for example, has to clear especially when shifted down. And for portrait orientation, the entire camera has to be rotated.
    3. cost is from $15k down to $10k, depending on Asian outlets.
    4. live view is available when tethered using Phocus via firewire on the external monitor right now, but not yet on the back's LCD itself
    5. speed of transfer for tethering is more limited using firewire compared to USB
    5. back is available with H or V mount

    comments?

    ****
    FWIW, a CFV back won't fit on an unmodified SWC (pre ~ 1980) because it won't clear the "quick release shoe".

    Do not know what the "Aptus rear standard" has to do with using this back on a Hasselblad V camera ??? But, if you are going to use it on a V camera, it is in landscape orientation, but some of us are going to use this back on a technical camera that allows it to be connected in any orientation.


    3. cost is from $15k down to $10k, depending on Asian outlets.
    Correct, at this time.


    4. live view is available when tethered using Phocus via firewire on the external monitor right now, but not yet on the back's LCD itself
    Incorrect; LV is available without tethering; see video links in above postings for LV demo.

    5. speed of transfer for tethering is more limited using firewire compared to USB
    The back uses FireWire 800 (IEEE1394b) for tethering/transferring. I currently tether a P45 via firewire and find no speed of transfer problems. Is USB 3 available with Phase One backs?

    5. back is available with H or V mount
    AFAIK, it is Hasselblad V mount, but can be used with other cameras via adapter plates from the specific camera manufacturers. I may be purchasing this back to use with an ALPA Max and STC, if so, I would mount it via my ALPA V adapter plate. I currently shoot ALPA cameras with a P45 and an ALPA Mamiya mounting plate.

    Correct. The extension plate is an "L" shape and allows for its use on the SWC.

    Not sure what "Aptus rear standard" means here? When mounting on a V series body, the CFV backs only have one mounting position, which is landscape orientation. This is not ideal, in my opinion. For technical camera users however, the back can be mounted in either orientation, or even upside down.

    Correct. Prices in Japan are BELOW $10K USD.

    I'm not 100% sure if the new firmware that enables on back live view is being publicly distributed yet, or if new backs are shipped with it already installed, but by all accounts it has been tested and works reliably. Videos from Linhof & Studio show it in action. In very low light the refresh rate is very much adequate for easy focusing and in good light seems better. There is no lag in the display.

    It's firewire 800, so should be more than adequate. More than speed, the bigger problem is that new MacBook Pro laptops etc. don't have firewire ports, although thunderbolt to firewire converters can be used. Again, not ideal if you're a hard core tethered shooter, but can be worked around easily enough.

    No. Only V mount. The H mount version is the H5D-50c and is significantly more expensive due to being sold with an H series body, etc.

    Re: Hasselblad CFV-50c live view

    thx, useful feedback as always.

    I am thinking of using the back on the Cambo Actus, which can be fitted with an H or V mount. this little gem (the actus) has a rear standard with shifts like a view camera and the downward movement of the back could possibly cause the battery to interfere with the standard. The Actus also has a rotating rear mount, allowing the P to L switch; again.
    clearances due to the battery need to be looked at.

    as far as transfer speed, Phase makes a big deal how USB 3 speed is critical in their IQ series for moving image files;

    problem with firewire might be no easy PC compatibility or modern Mac compatibility

    Maybe now they do - it's a selling point after all - but during the two year period when it wasn't working on the IQ backs they never appeared overly concerned - FireWire seemed to cope just fine.

    I very much doubt the battery would get in the way as it isn't flush with the part of the back that mounts on the camera, plus the standard battery doesn't extend down that much.

    While USB3 certainly wasn't topping marketing talking points during those "dark times" it was not at all the case Phase One wasn't concerned about getting USB3 to work. They invested heavily in bringing USB3 to the IQ and IQ2 as promised. Part of the issue, and why progress was so slow on this front despite continual R+D, was that USB3 was still a bit in the "wild-west days" and the variation from one manufacturer's USB3 card/implementation and that of another manufacturer was significant. Regardless the goal should be to under-promise and over-deliver and that was definitely not followed on this feature, at least as regards its time-of-delivery.

    Fortunately for all involved they did pull through and provide USB3 on all IQ and IQ2 backs as promised and having USB3, class-leading raw compression, and very fast and modern internal components (ram, processors, coprocessors) is critical in providing the Credo 50, IQ150, IQ250 fluid, high frame-rate, low-latency live view whether using the built-in Retina LCD or a high-res monitor while tethered by USB3. It's also critical in providing fast and consistent capture rates when shooting tethered, rates which can be sustained at maximum speed for hundreds of frames without hitting a buffer. USB3 is useful for the other IQ/Credo backs, but it's especially critical for the CMOS backs (Credo 50, IQ150, IQ250) since the CMOS sensor is capable of some very high data rates.

    As told in our Phase One IQ250 - CMOS Fully Realized article.

    Can we please not turn this thread into another plug for Phase?

    Re: Hasselblad CFV-50c live view

    Having had both the IQ and Credo backs in for testing at our studio, we have found USB3 to be "wanting" on several fronts, especially compared to FW800.
    1. USB3 does not provide enough power to charge the backs
    -real world result = dead batteries in the middle of a long day of shooting
    2. USB3 does not allow cable length longer than 9ft
    -real world result = cables run across floor and can be a tripping hazard or we now must purchase specialized new cables and active extenders to boost the weak signal
    3. USB3 is just as fast as FW800,but not faster, and can not handle sustained thruput the way FW800 can with aplomb.

    Not sure whats so great about it other than the first word in its TLA which is that it is "universal". They should have gone with Thunderbolt but whatever...It works and will have to get use to its quirks and live with it.

    The Hasselblad looks like a fine system and at that price, amazing! It was just an overall system and support decision for us but if we were a Hassy studio I wouldn't have given it a second thought!

    HB have taken a beating on the net over the years for various products they've put out, but this doesn't appear to be one of them. To be the first manufacturer to release a digital back with the latest sensor technology at a (relatively) sane price point deserves a huge slap on the back.

    If anyone is contemplating going down the tech cam / digital back route, then this is hugely attractive. e.g. in comparison to the IQ250:
