100-megapixel Phase One IQ1-100
This isn’t much of an update unless you count the two-images included.
We had a full moon this past weekend and I took the opportunity to try capturing it using a Phase One XF, Schneider LS 240mm lens and the new 100-megapixel IQ1-100.
My first thought was to use the 240 with the 2x extender thus making it a 480mm lens however I wanted to experiment seeing just how much of a crop I could get using the 240 as a standalone. The first image show 2-moons; the top moon is the original as shot while the bottom moon is the same moon at 100% crop. This was shot at f/11 1/200 ISO 200.
The image below is a 200% crop from the same night using f/11 1/200 ISO 100 for a setting. While not included, the full non-cropped version is the same size as the example above.
This is just an example of what a 100-megapixel medium format digital back from Phase One can produce. And yes I’m very pleased.
More to come

Shooting 100 megapixels medium format

My first digital medium format back was 16-megapixel Kodak DCS connected to a Mamiya 645 AF body. Little did I know that within a little over a decade I would be shooting a 100-megapixel medium format digital back!

Phase One introduced their first 100-megapixel full frame CMOS sensor late 2015 with delivery shortly afterwards. The IQ3-100 is so packed full of options one should expect it to weigh much more than a normal digital back; WIFI, HDMI and full integration with the new Phase One XF to mention just a few. And of course the price is just as hefty even with a generous trade-in/upgrade program. As much as I liked the back I saw too many things that I wouldn’t use thus didn’t want to pay full price; opting instead to wait until they came on the used market (which they have).

Early September this year I decided I had waited long enough. I’ve been shooting nightscape landscape images being forced to use a Sony A7rII and wanted to use medium format. I remember calling my camera dealer and very close friend Dave Gallagher and caught him literally as he was headed out the door to fly to Photokina 2016. I told him what I wanted and his rely was no, I’m not selling you anything – yet. Dave wouldn’t tell me why as he was on an embargo against disclosing details of upcoming Phase One releases that would be announced within the next couple days. Since I trust Dave with my family I also trust him not to steer me wrong. So I waited. Image my surprise when Phase One released the new I00-megapixel IQ1-100.

The IQ1-100 is everything I wanted without spending extra money for things that I no longer need/require. Since I’m no longer shooting with a tech camera I don’t need HDMI and since I can tether using my Surface Pro I don’t need WIFI. There are other differences which fit into what I consider “nice to have” however I’d much rather save several thousand dollars to use for say trips. A trip to Japan to shoot the snow monkeys or Alaska for northern lights or .. you get the idea.

I believe Phase One released the details on the 100-megapixel IQ1-100 on September 20th. The following week we were in Moab speaking to Dave Gallagher on the phone and ended up ordering it on September 28th taking delivery on October 8th. Not bad at all. The only thing that didn’t work in our favor was coming down with a cold which was bad enough to stop any work until just yesterday. In the meantime the 80-megapixel IQ180 has been returned as part of the deal and my credit card company is smiling.
So, what do you do to test a CMOS sensor that has beautiful live view, high ISO capabilities? Go someplace where you are in a dark place lit only with natural lights from very tall windows. We traveled south past Tubac to Tumacacori and visited a Spanish Mission founded by Jesuit Eusebio Francisco Kino in 1691 and is currently a National Historical Park.

Equipment used: 100-megapixel Phase One IQ1-100 digital back attached to a Phase One XF body using a Schneider LS 35mm lens. Since I wanted to shoot low and not use a tripod I opted instead to use a Platypod Pro Max with KPS geared ballhead. Since I knew I might be taking longer than normal exposures I also used a Hahnel remote shutter release for the XF.
So, was the upgrade worth it? Yes. Will I miss shooting with a CCD sensor now that I have a CMOS? Too early to say but I’m willing to bet no. How was the live view? Worked even better than I had hoped.

I’ll have more to share later from this trip as well as an upcoming trip to New Mexico where we hope to capture nightscape images so stay tuned.
