ok, a few DOF solutions, but how much?

How much we talkin for a WELL MADE DOF solution, i'm thinking of just making my own if they are going to be as costly as the mini35 (over 7 grand) i'd like to pay substantialy less than a grand if i can pull it off, or else im going to radio shack and grinding down a cd. Which ones are the good cheap ones?

BUY a Letus and it's over

Just buy a Letus35 www.adapterplace.com for a few hundred bucks and you'll save yourself so much in head ache, time, and money... Of course this is a DIY community... Kind of like Burger King... Have it your way......

If you wait a bit you can save yourself some money over the Letus. Jim Lafferty, a member of this board, is bringing out a low cost adapter that (last I heard) was going to be targeted at $209. Jim, feel free to correct me if I'm wrong. So far I've been very impressed with the footage from his adapter tests and I'd definitely recommend him if you are looking for a quality, low cost adapter.

before thinking of the Letus35, read this article, it is a shootout between the Letus and the SG35. basically the Letus sucked bad in light loss. about 3 stops. But the SG35 only last about 1/2 a stop. now thats an amazing accomplishement. but building your own is definatly a good way to go. you could build a nice one for under $80 if you think smart, and buy only what you need. ive already made a static adapter, and i am in the midst of building a spinning adapter. but i have a problem of making a good glass (or plastic) without getting hot spot.

I agree,
If you have the time, try building one, at least to begin with. Its a great learning curve.

forrest.. what article are you talking about.. you didnt post a link.. and im having probs trakcing it down on here.. from personal experience you dont get 3 stops light loss with the letus. i have the older version and with a 50mm 1.4 lens i dont detect much loss at all. definately nothing greater than a stop IMHO

If you have an older version then you probably don't see as much light loss. The version in the article is the 'flip' version, which DOES suck up a lot more light than the earlier versions that did not flip the image.

Also, in that article the SG35 doesn't get a fair critique. Ok, let me rephrase that. It gets a fair critique of the adapter that they received, but that is not the typical quality of the SG35. I have seen other footage that is MUCH better than that shown in the article. I'm not saying it's any kind of bias on the part of the testers, but from what I have read concerning this the adapter that was shipped was defective. And it is also being redesigned, so it will be even better in the near future.

Also, you can build your own relatively cheaply. Depending on what kind of GG you use (and other options) you can make the main tube assembly for as little as $60, depending on where you source your materials. The $209 adapter that I mentioned earlier will have a pretty dang good GG in it, and Jim does plan on selling it separately. You may want to look into building your own tube assembly and then using his GG. It's really not that hard to make these once you have the concepts down. But then there is a difference between making one that works, and making one that works well. Best of luck to you.

Also in that article, all the shots and footage and still grabs of the Letus35 were done using the unflipped letus35. the written part of the article was about the flip version, which does take up alot more light. but look at the old letus35 grabs compared to the SG35. those were done with the older, and lose a fair bit of light. alot in fact.

if you get yourself a good beattie screen, then you will be getting almost no lightloss, am i correct? thats what Dan states with his MPIC. which uses a beattie intenscreen. anyways, if you can make that screen oscillate. then your pretty much set. ttyl

I'd be down to buy one at that price range if it's for real and not a piece of junk... ...jim, you have a website?

go-35.com, though it is little more than a placeholder at the moment. If you'd like to see some high res footage from the $209 prototype, they are here:

http://go-35.com/vids/go35standard-lg.mov

http://go-35.com/vids/go35standard-lg2.mov

Low res footage from the Standard is the "Demo" link on that page, as well.

I also have DVX footage with the Go35SD ("standard"), but I'm hesitant to show it as in truth the adapter needs a proper achromat to work with the DVX at its full potential. The DP I rented the prototype out to over the past few days laughed when she saw the vignetting -- "You know, plenty of people pay a ton of money to get that look in post..."

Yes we did find the problem once i received the unit back after testing. Was a build error o my part, resulting in the dvx being about 5mm too close to the GG.

I am sending them an SGpro next month, so they can update the article.

You're looking at the Letus Flip version. Click the Letus35 link on the left side of the page, scroll to the bottom and you'll see he offers regular Letus models starting at $300.

Steven, how would you define "well made"? I'm interested in your point of view. It's not something often discussed in the current crop of adapters.
