Sunny 16 rule with 400 film: No 400 SS on any of my MF Cameras/Lenses. What to do?

[Arthurwg]

I have no idea what speed my lenses clock, but I understand that most C and CF lens are seriously slow at 1/500. Funny you're so sure without actual numbers. Glad you are keeping busy however.

Sirius:
Could you please share the name of service facility that you use that will adjust, calibrate and certify that my 'blad lenses are in spec? Do they cal Bronica lenses as well?
Much appreciated!

Speaking about lenses being slow at 1/500, what about the effect of the aperture on the actual exposure time?
I would expect the exposure to be shorter at f/22 than at f/4 because the shutter blades have to travel less to uncover the aperture.
Or maybe the shutter blades are just fast enough that it does not make any practical difference.
Any clue?

Henry has a lengthy discussion on this subject as well, Use of small apertures effectively lengthens exposure and is a significant factor.

Edit: Not Henry; it's Basic Photographic Materials and Processes, 2nd ed. "Effective exposure time" pp. 39

Shutter efficiency is a rather well known artifact to anyone who done a modicum of research. Especially with regard to the use of leaf shutters and flash bulbs!

I find EV's so much easier. Only 1 number to remember instead of the f/stop + exposure time.
Then you can remember a series of EV for each condition, for instance, ISO 400 and sun => EV 17, shade => EV 15 etc. (which is just another way of saying "sunny 16")
Arithmetics are also so much easier: use ISO 200 film? simply subtract 1 from the EV number you remembered.

I discovered EV when I started using a Hasselblad and now miss it on every other unmetered camera I use (e.g. Leica M3). I have an EV table in my cell phone just for this. Maybe I should just print out the table and attach it to the M3. Or quit using it altogether, medium format is so much heavier cooler

It does not seem to be generally liked, but I love the EV feature on my Rolleicord. It's convenient and I think it is easier to start getting a feeling for light levels.

Interesting.

Well, I hope in the near future to lern more about EV's...and since my lenses have markings for them...why not?


Thank you for your input!!

Do they cal Bronica lenses as well?
Much appreciated!

Bronica lenses for which model?
The GS-1, SQ, and ETR line all use Seiko electronic in-lens shutters, and the timing electronics are in the body.

For Hasselblads I use Samys Hasselblad repairman and Hasselblad
For the rest I use KEH and Carol Fluto

Either your camera is setup to hand EVs or not.

 

[MattKing]

Even if your camera isn't making direct use of EVs, a familiarity with the concept can really be useful.
If someone says that the meter reading was EV 15 at 100 ISO, I can instantly appreciate how much light is around.

Well, the OP was saying he enjoyed his Hassy due to it having EV markings...and I was implying since I have Hassy too (mentioned way earlier in the thread)..that I'd look forward to learning about EVs too, since I own a camera that works with them.

Me too, and on Retina and Hasselblad too.

On my new/old Retina IIIc and light meters.
