Is it true that Nikon don't have a MF equivalent of the Pentax 'A' Series?
i.e. They don't have a MF lens on which the aperture can be set from a DIGITAL camera body and also displayed on the LCD? They only have AF lenses that do that.

If it is true I'm surprised no one has picked up on it from the other mans grass is always greener brigade I'm sure they would if it was the other way around

Hi Stan, I take it that your using the foot on the lens and not the tripod socket on the camera?

I would have thought a 4" B&S would hold it. It's normal for the lens to drop slightly when you let go you have to aim a bit higher to compensate and you have to tighten the screw really tight to hold it.

It's better if you can balance the lens and camera by using a longer
QR plate on the camera.

There's nothing like having a really substantial B&S head with friction hold, but they are expensive. I use two Novoflex ones which are really solid. Arca is the top one.

I Love 'Polaroid Pied Pipers' and 'Instamatic Madmen'

Kodak once advertised photography as 'Simple as Blinking'

i thought the distance it triggers at can only vary depending on the distance the focus is set to on the lens, the point you are focusing at is static so going in or out with the camera should not change that i.e if you set the focus distance on the lens to 30cm move in closer than that to the subject then move out it will trigger at 30cm from subject or vice versa beyond 30cm from subject and move in focus is still obtained 30cm from subject so it should trigger or am i missing something Algi
I've tested most of my MF lenses using a Novoflex focusing rail which
has mm scale on it. I usually establish exact focus wide open by
LV and tests on a K-5. I then check how much in front and behind
of the 0mm position the Green Beep/Hexagon/CIF triggers and
adjust the micro-focus value so that it's either centred or
triggering when I move the camera in.

Actual Example....
Pentax-A 50mm f/2.8 Macro lens. 950mm from target to sensor position.

Triggered at -12 and +14 Setting -5 in menu.

So there's a range of about 26mm but the DOF is only about +/-7mm
so neither of the 2 CIF points would be in focus.
It might be with the lens at f/8

With macro shots and good eyesight just looking at
the image in the viewfinder is quite good.

Don't forget that CIF triggers at a different point if you
move the lens in towards the subject compared to if you
move away from the subject.

There are also two different points if you use the focus
ring from infinity or from min. distance on the lens.

Using f/8 to f/11 might lose this in the DOF.

You can of course change it to suit with the built in lens
adjustment compensation.

Who are Brand A and B?

Seems misleading to me?

The previous page made me laugh

Interesting shots. The first one is spoiled by the path being blurred?
It also shows quite serious moire on the roller shutter to the right
of the man.

There's also moire on the aluminium above the handrail on the second shot
and on the sloping roof of the last.

Is the moire due to the camera or processing.
