    Re: fat pixel digital backs

    went to mineral king in sequoia national park yesterday to get out of the valley, 104 degrees. unfortunately mineral king was warm and on thursday night/friday morning there were thunderstorms which ignited a fire. the park service was right on it and helicopters were brought in to dump water on the fire, which was put out. but smoke brought a haze to mineral king valley which made shooting difficult. also when wife and i left for our drive up, my truck had ash from the fire near yosemite. here in california, with over 100,000,000 trees dead, fire is a major concern.

    Re: fat pixel digital backs

    i just noticed something. just uploaded an image of rialto beach. instead of using my laptop i used my desktop that i use only for photographic work because the monitor is calibrated. on my desktop the image looks really nice as an upload to this website, on my laptop the image looks a little gritty and on my wife's desktop, it looks somewhere in between. i knew that there would be some difference but not to the extreme i am seeing. so when we upload an image here we can only hope that a person viewing an image has a screen that is positive for said image. i went back through all the pages on the forum to look again at the images posted, using my desktop, and images that i thought were so-so on my laptop took on a new quality on my desktop.

    Re: fat pixel digital backs

    i tried to post this yesterday but for some reason it wouldn't work.

    when i posted the image of rialto beach, i did it on the desktop that is only used to process my images. the monitor is calibrated. the jpeg posted on this forum, viewed on the desktop looked very good. i decided to view it on my laptop and the image looked gritty. so i tried my wife's desktop and the image was somewhere between my desktop and my laptop. i went back and looked at all the images on this forum with my desktop and images that i thought were so-so on my laptop, looked so much better. i guess the moral of this post is, your image will only look as good as the monitor it is viewed on.

    Re: fat pixel digital backs

    hasselblad lens question:

    i have the 80mm lens for the h3dll-22 camera and thinking of purchasing a second lens. it is only used for b&w landscape photography. new lenses are out of the question because of price. for my nikon d850 i only have zeiss primes, but because of size and weight of multiple primes, i was considering the 50-110 zoom which i know is one heavy lens. i have read both good and not so good reviews. because of price i was looking at the older version. for the wide end, at a later date i will pick up a 28mm lens, so no need for the 30-90mm lens. does anyone here have the larger zoom and what are your feelings on image quality or would the 120mm or 150mm be a better choice.

    50-110 is a spectacular lens..excellent acuity at both ends..it is heavy

    I adree with Stan about this lens. It is a fine lens if you can put up with weight. I eat one banana for some energy!
    This lens, I am sure you can find at a good price.

    Hi,

    is a P30+ with its 6.8Ķ pixels considered a fat pixel back ?

    To me Fat Pixel is strictly 9 micron. But then again, what about 12 micron ?

    How did I go for so long without seeing this thread !! Spent the last 2 hrs going through it.

    So, 2 questions: if I was buying one, (have an H1 with 80 f2.8 that's collecting dust since years), what would you choose between a P30+ and a P25 (H-mount) ?

    Also, does the exposure count make a difference when buying one? ie, do more exposures = worse quality / attrition?

    Thanks!

    Since there are no moving parts in a digital back (except for fans in some models, but not the Phase backs) then the shutter count does not necessarily matter.. how it was used matters quite a bit more. I.e two backs with 20,000 exposures, one never left the studio and one spent most of its time outdoors in adverse conditions that may be closer to a failure of some kind.

    That being said, I did hear of one such studio-bound back with a low shutter count that failed. It turned out that although the shutter count was low, it was nearly always tethered and spent a lot of its life on, and therefore contributing to the death of the back nonetheless.

    Wait, are you saying that some digital backs have a moving fan? That blows me away. For astro, we've used piezo cooling for years.

    Yes, at least Leaf aptus backs were made with a tiny cooling fan in the design, and I believe some of the Hasselblad CFV backs do as well. This, along with the associated vents, is one of the reasons why Phase backs are seen as more rugged or fit for outdoor use than others, as they do not have vents for sand/water/etc to get into or fans to fail.

    Re: fat pixel digital backs

    Btw I wouldnít be overly concerned by the fan in the Aptus backs. Iíve had a couple and other than the slightly annoying whine, they never caused any problems out in the field. I always worried about this but in the end it was never a concern, even in the rain. Ditto with the CFV 16 I had for a while.

    I would agree though that there is a certain peace of mind with a passively cooled back like the P+ & IQ backs.

    Re: fat pixel digital backs

    ^^ what Graham said. I should have stressed that the passive/active cooling argument is just what SOME think and say... Iíve never had a problem with my aptus in any condition and I suspect there isnít a huge difference in failure rates between passively cooled backs and actively cooled backs.

    An argument in favour if active cooling would be that it is much more likely to maintain a healthy temperature in hot/humid conditions than a passively cooled device. I have had problems with heat shutting down passively cooled computer components, amps, and speakers and Iím sure that actively cooled components would have fared better in all cases. Just because something is passively cooled is doesnít guarantee itís function in all cases; the designers are usually counting on a certain amount of airflow around the cooling components to dissipate heat.

    All this to say: donít get hung up on which backs are more or less likely to fail as itís a total crapshoot. Buy one that has the features/sensor you are looking for within your budget for your system of choice and enjoy. They are pretty much all as equally likely to fail as not.
