Yes I'm afraid I have another adaptor.

marlene.. i am using a sonia +10 that is attatched to the camera.. and then an asian +10 inside the adapter.. both cheapos.. so it might be that which is causing blur... is the only macro your using the co-7?? because even with just one +10 i cant get zoom in far enough to cancell out vingetting..

Little doubt that your edge blur is because of the macros. And what do you mean "+ 10 inside the adapter"? I think you're just asking for poor quality with what you are using.

I've tried a lot of combinations and what's working for me is the +7 CO and a +2 Close Up. Did you look at my resolution test with the least amount of zoom I could get away with (76zoom), a little more zoom maybe to 78 or 80 and there would be no vignetting. The test does show that the combination of +7 CO and +2 Close up are giving me acceptably sharp edges. I wish I'd done this same test with the Asian +10 Macro and +2 Close up as you'd really see how bad the edge sharpness is.

het guys here is my new test
it was done on an old trv-27 and with the beattie screen.
the beattie is currently my fav.
the vingetting is from me not zooming because the zoom on the camera is real fast and sensitive.

but when i do zoom, everything is bright and looks great
i am using a 18+ tiffen macro

Why didn't you do the test with proper zoom and the camera on tripod? You say that your cam has too fast a zoom? You also say that when you do zoom, everything is bright and looks great.....so why not show us that footage?
 
Dan- would love to see the "master" at work @ the 35mm Internet school.

Was wondering if building a adapter was more fun than making the movie?

Marlene- can you share with us the Beattie screen model number, size your using?

I haven't tested a Beattie screen. I've only worked with the Nikon Type D, Wax , DIY Ground Glass, and the AOL screen.
 
opps sorry marlene,

today was a hectic day, i had to bring back to school: a sony z1-kit, tota lights, c stand, 10 feet green screen, atw wireless mic, 501 moffetto tripod, and steadicam flyer, all this was done in one hour and also stuffed into a civic sedan.
when i got everything in, i had an job interview at 1 pm plus a anthropology confernce to do tech for.

i only allocated 2 hours to test on that trv-27. I only zoomed in for my vitewing purpose to see if i had barrel distoration or vingetteing, and they were no there. plus the fact that my hands was shaking, i was going wide as i can so i can just show how the beattie worked even if i was not zoomed it.

but i will have the equipement back on thursday and will shoot on a tripod to really show the setup,
 
MArlene. Question for ya.

Out of all those screens youve tried, could you please list the pros and cons and then order of preference? Im ready to wait to ordre a nikon type d screen from b h but they are out of stock right now.


Also, i see you use a +2 macro instead of a +10. Is therel ess distortion on a +2? Can one use a +2 on a dvx100b and still have enough to zoom in and focus at that close detail? Does that make sense?
 
Thanks Steve,
I enjoy the two processes (making and using it) equally. I have two very unusual orders (custom MPIC) and I will post the pics when finished. None done before (as far as I can tell) and not available for any other source. Custom work is fun and keeps me "mechanically challenged" (the least to say):happy:
 
Dan,

I'm totally in for a 35mm university. I think an actual comparison of available materials would REALLY help out this DIY community. We're throwing everything but the kitchen sink into these adapters, but not always with the best results. As many of us are visual learners, I think the ability to see the process would be most helpful.

Ahaaaa... so you just found out on your own what's missing!....BRAVO!!!!
lol
Well... to be honest, I did not try it either, but I did drop one MPIC in the kitchen sink once and nothing spectacular happened (but that wouldn't count anyway, right?)
Well... let's wait see if anyone else is interested and we'll take it from there.
I got banned from DVI for my findings must have hurt some people's business. I don't want that to happen again here. Freedom of speech is granted as long as you don't know what you are talking about! (I figured this one on my own! hehehe)

Steve, if you mean the 35mm format, you’re looking for the 82430, made for the Contax RTS II. There is another one made for a Nikon that would work, but it is slightly smaller.

Dan gave prime advice as for the use of a Beattie in a static adapter. You will soon find out the grain is too much. On the other hand, it’s a great solution for a dynamic adapter.

HTH,

I'm using a +7 CO and then a +2 close up. My minimum zoom is about 78 to avoid vignetting and obtain focus. The combination works fine.

As for preference of the screens I've tried.

Best....Wax.
Pros.....least "grain" and can be very brite.
Cons....hard to make ...lots of patience and redos.

Very Good.....AOL CD Case
Pros....minimal "grain", brite and free
Cons...hard to find for some and then you need to have a scratch free,
defect free area on the case big enough to cut out for your screen.

Very Good...Nikon Type D
Pros.....minimal grain and pretty brite.
Cons....hard to find and dust can get between the condenser and screen

Very Good....DIY Ground Glass
Pros....if you use the right grit and do it right, it can be smooth, even
and brite
Cons...hard to make grainless, mine had grain so I need to try again

As I said before, I haven't tried a Beattie yet but the easily scratchable issue tends to make me not even want to invest in one. All screens need to be free of dust so they need to be blown off and checked prior to filming. Dust specs are hard to see on the small LCD or through the viewfinder. Using a 7" monitor really helps you see if you have any dust on your screen. You don't want to see it on your computer monitor after filming something important.

The best thing to do is to make your adapter so that you can easily exchange screens, this gives you the option to test screens and also exchange screens for different effects. I've started to view screens as effect filters that can be used in creative ways so I plan on creating some screens just for creative enhancement such as soft focus or fog.

Remember, the above list are only the screens I have tried, there are many possibilities out there. In fact, I layered several pieces of sandwich bag material and got a pretty nice effect. The important thing to remember when trying out free materials to use as a screen is that they must be free of any pattern or distortion such as the beer cup screen unless that is the effect you are going for. One of the DIY GG screens I made, that was really a reject, gave me a old film look so it's in my bag of tricks in case I ever want that look.

It seems that a lot of people get hung up on the screen issue when the real issue is with the diopter you use. Before anything else you need an aberation free and sharp image. The lens that you put on your DVX lens really must be achromatic.
 
marlene,

What grit grinding powder did you use? (and how does one get on the AOL snail-mail spam list?!?...)

Aluminum Oxide, 5 micron and then 3 micron. I purchased the grit at a Jewelry Making Supply store near my home.
 
You need to breed Felix and include a little Felix with each MPIC:) Everything is growing fine thanks for asking lol. That footage leaves me feeling thirsty, looks good as usual.
