The 907x Has Landed ...

Nice group of images!

Thank you for the compliment, Pál. 🙂

The 907x's CFVII 50c back also works very well when used with the Hasselblad 500CM body.

What's the crop factor on the 500cm??

What's the crop factor on the 500cm??

The film image out of an A12 back is 56x56mm with an 80mm lens. The CFVII 50c sensor is 33x44mm in size. Graphically, this looks like the attached illustration.

If you crop the sensor square (for like proportions) to 33x33mm, the resulting "crop factor" is 1.7x. So an 80mm lens on the CFVII 50c, when cropped to square, nets the field of view that a 135mm lens would on an A12 film back.

Thanks G! Appreciate the comparison. It makes me wonder what a true 1:1 sensor would cost one day, or if there's even call for it.

that sensor must be sheer horror to keep clean. 😀

I haven't seen much if any dust show up, and I've swapped lenses and the back back and forth between the 907x and 500CM bodies with little care. I don't think it's all that big a problem at this point. 🙂

It is extremely easy to clean, however. Just take off the back and blow on it with a blower bulb.

I'd love a 56x56mm sensor but I suspect it will be pretty darn pricey if it ever surfaces.

There are larger medium format digital sensors currently available, but the cameras and backs that have them tend to sell for 2-4 times what the 907x Special Edition sells for, and it's fairly pricey by my standards as it is.

I'm content with this: It does what I was looking for and was within reach financially. 😀

My walks continue: I've been shooting a good bit and processing slowly, playing with various ideas using the Hasselblad 907x and CFVII 50c back, along with the 500CM and the same back. It's the only way I learn things.

I did my walk with the CVFII on the 500CM with Planar 80 a week or two back, and have been walking with the 907x and 45P lens this past week. Here are two walk pix I like. 🙂

Poppies - Santa Clara 2020

Stone Unicorn - Santa Clara 2020
Hasselblad 907x + XCD 45mm f/4 P​

In the course of swapping lenses, backs, experimentation, I found on yesterday's walk pix a nice big bit of schmutz had gotten onto the sensor. It barely shows up at lens openings under f/5.6, is crystal clear at f/16. I took the back off, took out my Giottos Rocket blower, and with one puff the sensor is completely clean again. Whew! Also, I selected all the frames I made yesterday in LR and tapped the spot with the spotting tool: it's removed. Some of them need a little editing work, but overall it shows me that for my use I don't really need to do much more than normal care and diligence in swapping lenses and back with this system.

Be well, stay sane, keep on going!

The cactus plant that lives on the patio has five blossom buds this year. One of them opened yesterday ... The blossoms are short-lived, usually gone in 24-36 hours, but they make the most of it when they're around.

Cactus Flower #1
Hasselblad 907x + Summicron-R 90mm f/2


Cactus Flower #2
Hasselblad 907x + Summicron-R 90mm f/2​

The Leica Summicron-R 90mm f/2 works well on the 907x using the electronic shutter and covers the full 33x44 format pretty well, I saw little to no corner darkening. On another subject that had hard edges in a more contrasty light, I saw that it produces small bit of red-purple fringing that cleaned up easily with the LR Classic defringe tool.

Enjoy!

I know I was in Arizona when they were blooming, by the time I left they were almost gone. Nice photos, my neighbor took out here cactus so no blooms around here this year. You seem to be able to put any lens on that rig, lots of fun; especially during a lock down.

So far, most of the Leica lenses I've tried work passably well, at least on the 33x33 cropped format, which kind of makes sense since they were designed to cover a diagonal of 43mm.

The R lenses tend to work better than M lenses because the M lens mount diameter tends to cause a bit of hard vignetting.

Sometimes I've found there isn't enough real benefit to warrant using the lens, for instance the Super-Elmar-R 15mm and Elmarit-R 19mm produce usable coverage that is only barely wider FoV than the XCD 21mm .. By the time I crop down to within the corner darkening and vignetting, I might as well just use the XCD lens and get perfect full-frame coverage.

All of the V-system lenses I've got have tested out beautifully, once I either spend the time to carefully focus them with the 500CM viewfinder OR switch the back to Live View for focusing and framing. They work beautifully on the 907x ... it's doing that same thing.

Of course, with any of these adapted lenses, there are some constraints simply because you're using the sensor/back's electronic shutter facility. It's best using them with relatively static subjects, short exposure times, and works best with the camera on a tripod as well so as to minimize body motion, all because of the sensor read-out speed.

The adapted lens scheme works well for a lot of my typical subject matter, but I know that the Hasselblad XCD lenses are really the way to go for best quality and best flexibility.

Nice are shooting with the 45mm mostly?

Thanks!

These were made on May 11, quite a while ago in the scale of moments this past month and some. They're part of several sets of photographs I've made with the 907x, the 500CM with CFVII 50c back, and other cameras (645, pinhole instant, regular Polaroids, etc). So it's hard for me to answer with confidence "shooting mostly with the 45mm" and say that is really accurate or my perception... 🙂

I've actually done more exposures with this camera using the Macro-Elmarit-R 60mm lens on a copy stand to capture negatives and Polaroid prints than anything else at present!

The XCD 45P is a very handy lens, however. Its FOV and size makes it a natural for all-around shooting, either in my usual square crop or on the 907x full frame.

I will say: The 907x needs a grip to really be most handy for me ... and not the "full function", eye-level oriented grip that Hasselblad has previewed for it. I want a grip that allows me to use it waist level easily, viewing via the LCD, which from my perspective means a left-side grip. I'm cobbling one up at present.
