Hi! In an attempt to avoid flicker, I read an article in stopmotionpro, which says:
"The lenses that are supplied with modern DSLRs use automatic iris. When you click the shutter release, the lens iris 'stops down', the shutter opens, after the set exposure time, the shutter closes and the lens iris opens up again. Unfortunately the lens does not 'stop down' to exactly the same place each time you press the shutter. It causes an annoying flicker.
To solve this problem, the best solution is to use older style manual iris lenses, not to use the lenses that usually come bundled with the new DSLR cameras."
So, I have a camera Canon Eos Rebel Xs 1000d, and I want to buy an adapter lens eos for a 45mm MINOLTA MD Rokkor 1:2. But, there are two kinds of adapters:
- With electronic focus confirmation
- No focus confirmation
To avoid flickering, I can use any of this adapters? Or should I buy without focus confirmation?
Nova flex adapters have been used to attach m42 manual lenses to cannon bodies with good results but are very pricey. I found exactly the same thing for about £5. As far as i can tell it works wonderfully for fitting pentax M42 fit lenses to my Cannon 550d and eliminates flicker produced with the auto lenses. I know this doesn't help much as the fitting will be different for your manual lenses but something along these lines should work in theory.
For the price of a Novaflex adapter, you can buy a used Nikon Micro-Nikkor 55mm F2.8 AI-S Manual Focus Macro Lens and an adapter(has no glass) and still have change to spare. These used lenses can be bought on Ebay. You want to buy a Nikon (AI or AIS) lens..not an AF.
There can be several sources of flicker. First, don't wear a white shirt because it can reflect light back on your subject and cause flicker. Second, check settings on yoour camera and remove any auto adjustments such as white balance, exposure and etc. Third, try using compact flourescent bulbs. Fourth, if all these fail, then you need something to smooth the voltage going to your lights and camera.
Perhaps longer shutter speeds and lower ISO's? Not sure, just a thought.
Has anybody tried or have had any luck with pancake lenses?
I was looking at these the other day and thinking about stopmo applications.
