I am using a Canon 40d EOS with the Dragon frame program. I have a non-digital, manual Nikon lens (with adaptor). They have a new product advertised as the "lens correction cap", which allows a "zeroing out" of my digital camera's settings. My impression is that this will allow a better live view exposure during animation. Perhaps I will no longer have to deal with the very dark live view screen.
Dragon Frame's website claims that my camera will remember the last f-stop setting of any digital lens that was mounted on my camera body. So...
Couldn't I just briefly attach a digital canon lens with auto-focus, open up the aperture to lowest setting (2.5 or whatever) , then re-attach my manual nikon lens for animation? Wouldn't I be re-setting my camera body's aperture setting to 2.5? Then Dragon Frame would take it from there, and my live view screen could be brighter?
I am just thinking of a way to avoid spending the $65 on a cap that I will only use once. Perhaps I could put that $65 towards a digital lens for non-animation use.
Any reviews of this lens cap or possible solutions will be appreciated.
With the correction cap being the next item on my shopping list, I too would like to know if there is an alternative.
So, to answer my own question....
Yes, after attaching a friend's digital Auto Focus lens to my camera body, I opened the aperture all the way up. Took a few shots, then removed his lens. Once I re-attached my manual Nikon Lens, and connected up to Dragon Frame, my live view was much brighter. Problem solved, no need to buy the Lens Correction Cap.
This is Jamie from Dragonframe. If anyone has a real solution - please let us know. We tried everything for months including - bugging Canon to help us find some way to reset the value. The cap was our solution (at my personal studio) and so we are offering it to others.
Opening up a digital lens will get you close but not perfect- you could also use Dragon's Exposure Preview compensation to go the rest of the way. That said - our Live View Cap will take the f-stop to f/0. Which tricks the camera into a perfect match for your live view. Also - we have noticed that sometimes the value changes during camera use like once every couple months - and so we use the cap again. All very strange - for an issue that the camera should not have. In fact, when you place a manual lens on - the exposure values and light meter will be correct - so the camera knows what is going on - it just doesn't communicate this to the Exposure Simulation equation. Duh.
So - yes, if you have a digital lens that opens to f/1.4 - that will make the live "Brighter" - but it will still be darker than what you are really shooting.
Thanks for the information. I will keep an eye on my live view and see if it darkens over the next couple of months. Having my live view actually match my shot frames is very tempting. So I might be ordering one of the lens correction caps from you in the future. Keep up the good work over there at DF!
I finally ordered the lens cap correction from Dragon Frame. It works like a charm, and has been a great help to have a crystal clear live view window for my Canon 40D.
Anyone here able to ship it so I can borrow it? I'll pay of course. They are out of stock on the website.
