 |
|
I was playing with my Kodak Hawkeye 110 lens on a D200 and found that when stopped down, all the way to f/64, there is much PP work to be done.
you can click on the PIC to see the Orig...
Every problem on the sensor shows, and IMPO... this is far to much work. This is the last time I use this lens stopped down this far. I think I'll just leave it @ f/8 in the future... BTW, cleaned this sensor about a week before this shot was taken. Even f/16 doesn't show this bad.
So, what do you think?

I found out that if you have a really really small aperture and a really really long time, it will show dust on the lens aswell. just like in macro.

So, what do you think? |
I was taught the technical basics of photography in the early 60's by a man who must have been nearly 80 at the time, almost old enough to be my great-grandfather. He used a folding camera, I don't remember which, and he first learnt his skill in his twenties, well before WW1.
He used to say that you should always try to take pictures with the lens at its "standard" aperture setting - i.e. when it's closed about midway, around f8 or 11, and adjust the shutter speed to suit. Only when the available light, the film speed or the camera's shutter speeds make it absolutely necessary should you adjust the aperture. The theory is that the lens is at its peak performance at mid-aperture and any adjustment away from this, up or down, degrades the picture.
Technical advances in lens design and film manufacture have given us a lot more freedom than he had, but the principle is still true.
What is the f number for the widest aperture on this lens Chris?

@ ChrisLilley... Actually the cam takes PICs. The "other thing" is just a bunch of sand! 
@ Nesster... Thanks for this education! That link tells much. Looks like there used to be a bunch of "systems" for calculating stops before ASA stepped in.
@ peterqd... Looks like it runs from US stop 8 - 64 (for US stops, read more @ Nessters link), f-stops of ~11-32. And I was just playing with it to see what I could render. Looks like it will be wide open with any shots in the future...

At least in the digital 35mm realm...

Well, you can use it as a sensor check, definitely lets you know when to get it cleaned.

I did a cleaning over the weekend and expect it to be a bit better. But anything over f16 should still be avoided with a digi-bod, IMPO. And usually f5.6-11 is the sweet spot in the 35mm arena.
