Yes, I think there is.
Though I would not call it cheap by any means it will be less expensive than getting 35mm lenses and an adapter. They a4re called diopters and they are ment for extreme close ups in macro.Century makes some good ones for about $600 and it has a magnification of 2.6x. Heres the link, Hope this is an option for you.
Thanks.
I´m not sure if I can film an ant with it.
Have you used it?
Couldn`t find a step up ring to 86mm either.
Does Schneider Optics manufacture quality lenses (never heard of them)?
Schneider it top notch and is now owned by Century, It could also be the other way around but no worries. Yes they are of fantastic quality for a lens add on. They do also sell the step down rings, I'll give you the link. And It should get you pretty close. How close are you wanting to get? Like one ant taking up most of the frame close, or like ant's head taking up the frame close? If your just trying to get one ant in the frame then it should be pretty close but for anything closer you will have to use a different more powerful macro lens. Give the reps a call they are very helpful even if you are not trying to buy anything. They can give you some actual figures like focus to distance ratios and what size objects you can shoot and fill the frame. Hope that helped.

An ant`s head taking up the frame close would be great, but I guess I need a different lens for that. If it is not possible or way too expensive, I can live with an ant`s body filling the frame.
I`ll talk to Schneider monday. Until then more information is appreciated.
Is 2.6x enough for my purposes?
I have used it, it works great. I think it was around $500.00 to $600.00 per day and worth it. With a normal lens, you will never fill up te frame with an ant much less get an ECU with the ant's head filling the frame.
