I hope this series of video tutorials is less confusing than the last one I did. But first the written details.

My Materials List:
Canon FD 50mm 1.4 Lens $70 Ebay
Canon FD Mount $13 Ebay
Focus Screen $ depends on what you use, I've had success with an AOL CD Plastic Case but a Nikon Type D Focus Screen is good if you can find one and you can find tutorials on making a wax screen.
72mm Macro Filter $25 Ebay
72mm Cokin Series P Ring $8 Ebay
Scrap piece of 2" ABS Black pipe $2.00
2" ABS Cap $2.00
2" ABS Coupling $?
2" ABS Cleanout Body $?
JB Weld $4.00
Sandpaper

Tools:
Drill
Jewelers Screwdriver
Hacksaw
Dremel

Here's what the materials look like layed out

The distance between the front of the Canon FD Mount and the end of the "connector" is critical. Start with about 43mm from front of lens mount to end of connector. Tape a piece of diffusion material (like you get from Lee's Filters) on the end of the connector, put on your 2"coupler and look through it at a distant object with the 35mm lens attached, focus on infinity and see if it's sharp. If you come up short on the focus (meaning your lens is on infinity but your distance didn't come into focus yet) then you need to sand down your connector. If you come into focus on your distant object before reaching infinity on your lens then your focus screen is too close to the lens.

I forgot to mention in the video that it is important that your connector is perfectly flat, if it's not then your screen will not be parrallel to your DVX lens and you won't have a sharp image from corner to corner.

If you are going to use a Nikon Type D screen then you may want to check out my previous tutorial which shows how to mount the screen.

Here's what it looks like finished, but I use that term loosely :)

Here's the video tutorials in 3 parts:

Part 1 http://homepage.mac.com/marlene.mac/iMovieTheater19.html

Part 2 http://homepage.mac.com/marlene.mac/iMovieTheater20.html

Part 3 http://homepage.mac.com/marlene.mac/iMovieTheater21.html

There are several ways to make these, experimentation is good. This is just an example of where to start. I even have plans for another design.

Hope this helps.

Marlene, what type of shade is on that lens? it's a canon right?

The shade is an Asian brand that I threw in with an order for a macro. It's metal and works great with no vignetting.


And thank you MovieMakersClub.

Thank you.....I'm glad you enjoyed the tuts.

Once you have the parts it doesn't take long at all to put together. Probably the longest part is getting the "connector" the right distance from the lens mount, once you get it close you have to sand it.

I'm glad that you're going to try this, it really is quite simple and fun to make.
 
Just finished watching your latest tutorial. THANK YOU!! I can see clearly now... sorry for the pun. Although I've been searching high and Lowes for the end cap (#5817) for the lens-mount and no one has it around here!!! Neither Home Cheapo or Lowes that I've been too (closest ones around). Although I just got off the phone with the Plumbing supply down the block from me and they might have it!! bloody ironic. Just waiting for the Macros and P ring and I'll building this out!

Thanks Marlene for the inspiration, advice, and tutorials!!

My local family hardware store often has more to offer than the chains. Hope you found it!

How do you cut the connector so that both edges are parrallel? Band saw?
Click to expand...

Funny you should ask......that to me is the hardest part. I use a hack saw and try to follow my measured lines as best I can, then I lay sandpaper on the workbench and sand it. My workbench is level so I use a bubble level to get both sides parallel to each other and the cap the "connector" is going into. I'm sure there's a better way but that's just what I do.
 
Just a Thought.
How about using a Macro Bellows before GG (found el chepo new for 89$) so you can use more than one brand of lense (via premade adaptors), mark your lense focus points on rail.

Thank you....it is responses such as yours that making sharing information so easy to do.
 
Since making this tutorial I have since traded out the +10 Asian Macro for the +7 Century Optics Achromatic Diopter. I added a 2" spacer so I wouldn't have to use the Asian +2 close up. I strongly advise not using the +10 Asian Macro, the aberations are bad and it's just not sharp on the edges.
Here's my latest test

Spend the $200 for a 2 element achromatic diopter....it's worth it!
 
Marlene the footage looks great. There's something about adapter footage that is a blast to color correct and color grade. It seems a little flat right from the adapter...very even. But bring it in to your NLE and boost the contrast and colors and it looks great.

Quick question, is the CO achromat right in front of the DVX lens, or is it further away, closer to the focus screen?

The +7 is attached to the DVX lens by means of a step up/step down to the Cokin ring, so yes....it is right in front of the DVX lens. It's also important to note that if you need to use another close up such as a +2 or +4, that you put that on after the +7 CO. In other words.....the +7 CO should be the first piece of glass directly in front of your DVX lens.
 
Thanks Marlene!!! What a great thing you've done. I don't care for the term (overused), but in this case it fits...."you rock!!!".
 
Marlene,

sorry if you have answered this before (I searched and couldn't find it).. but what and how exactly are you using as a screen again? I guess I don't understand the AOL disk description.

Thanks!!!
