Thank you John, I thought there where only a few that did it.

Edith Shain passed away at the age of 92 last Sunday.
If you've no idea who she is, I don't blame you since I didn't know either but we all know the photo she is in so she will never be forgotten.

V–J day in Times Square by Alfred Eisenstaedt
Comment Image

Description what happened according to Alfred Eisenstaedt
In Times Square on V.J. Day I saw a sailor running along the street grabbing any and every girl in sight. Whether she was a grandmother, stout, thin, old, didn't make a difference. I was running ahead of him with my Leica looking back over my shoulder but none of the pictures that were possible pleased me. Then suddenly, in a flash, I saw something white being grabbed. I turned around and clicked the moment the sailor kissed the nurse. If she had been dressed in a dark dress I would never have taken the picture. If the sailor had worn a white uniform, the same. I took exactly four pictures. It was done within a few seconds.

Matt look at your EXIF data with the lenses with a digital info contact you've some form of focus distance.
Also Dimitrov talks about it. link
The F 50/1.7 at most 16 different distance settings according to him.
Good enough I think show the relative interesting part of the chart.

But going back on topic, which zoom lenses do have a DOF besides the few lenses from the Pentax A series?

thanks Gareth - yep, 47mm of tubes. I'm a real close-up junkie
You could reverse mount the 28mm onto the 100mm macro, it will give you a 3,6X magnification. Don't know how close you need to get though.

I've tried it once with the DA40 but the DOF is very shallow even with that lens.

I've truly never used a DOF table, if I want to know the DOF I simply use the optical preview. I'm probably just too lazy too look them up I think

Old zooms often have DOF scales, but usually only the trombone type.
Yes only some lenses from the Pentax A series have the scale on the "zoom" tube but older lenses like the M or K series don't have it.
Don't know how it is with other brands?

Far better to use DoF tables, there are some good iPhone apps.
Sorry I don't understand it really, do you mean it's not on the newer lenses because there is an iPhone app?

Actually you brought me on a good idea, why can't they display the DOF scale on the back of the LCD screen? Lenses these day give away the focus distance they are so it should be possible.

Have you thought about getting a Stofen diffuser, they're great at really softening up the flash
Stofen doesn't do a lot outdoors besides eating one stop of light.
Stofen relies on that it throws the light against the ceiling, the walls and the ground in the hope some bounce backs to fill in the shadows so it only work indoors.
They are after al not called omni-bounce for nothing
Lumiquest explains it with pictures link

To get softer light outside you either need to create walls to bounce the light off from it or make the apparent light source larger.

So for outdoors a small softbox like the ones from Lumiquest are your best bet or a bounce card.

AA are batteries right or not?

Can I zoom whilst filming? (I am assuming I have to focus manually?)
yes you can zoom and focus manually but you can first auto focus before filming.

Can I pre select aperture or is exposure fully auto in video mode?
Yes
Quote:
Can I change aperture mid shot?
No... actually you can with a lens with an aperture ring not 100% sure about the rest though.
Quote:
What about speed? or is that done via ISO?
Speed is 30FPS I believe nothing you can do about that and with the ISO the camera controls exposure.


Please correct me if I'm wrong with anything

You might notice something with the AF 35-70 f/2.8 maybe?
But it use his own batteries I believe.
