It is not as Bright as the Brevis? I can't wait till Dennis sent you the flip unit. It would interesting to see how they match up . When both adapters offer flip image and one has light smear.

I think the Letus will win out against the Brevis with the flip. Apparently the letus loses just half a stop, very similar to the Brevis CF1. Not sure how much more the Brevis flip loses, I think it is around another half a stop.

I would be very interested to hear if Redrock are planning to catch up with the competition...They haven't touched their M2 in ages whereas the Brevis is constantly being revised and the Le brothers have stuck a big two fingers up to P & S and Movietube with their adaptor.

Now, all they need to do now to make me happy is bring one out for the JVC with a relay. Now that would be one sweet combo.

For aerial image pass-through, tighter apertures are not going to help much except for reducing the actual soft area around the pinpoint so it may be less apparent as an artifact.

You may find you have to use a polariser to dull reflections down a little and maybe do some tricky things with black-stretch in the camera if you have it, to pull down bright highlights and bring up the dark detail to compete for attention in the image.

As a mater of idle interest, try 1/100th sec shutter to see if the groundglass fixed pattern artifact comes back. If you can wring 1/100th sec out of it, this will make a few music video folks who like to shoot a sort of slowmotion quite happy.

...i second that jvc relay...although id prefer it if Dennis came up with one first...

For those who are desperately impatient and already own a Letus for JVC, chances are, and I must emphasise "chances" -- with all the uncertainty, grief and malaffection that comes with uninformed comment (mine) subsequently acted upon by innocent others (you?) with disappointing outcomes ---- got this far ---

okay caveat expressed --- and Quyen, please beat me down to a quivering pulp of bundled neuroses if I am wrong so no harm be done, ----

---- chances are, that the relay for the original Letus35 flip for JVC GY HD100 might be in the meantime usuable from the flip module rearwards with a small mod, on a LETUS Extreme or maybe more easily, on the LETUS economy.

Almost certainly, the bridging tube from the rear of the flip enclosure would have to be carefully drilled with precise screwholes to match the screw fitment of the bridging tube on the Extreme. The internal diameter of the bridging tube might need to be skimmed to match the diameter of the rear shoulder on the Extreme but it may not if the same tube material has been used on both.

RE: JVC Modular addon
 

Posted by Hien over at LetusDirect regarding the JVC

Modular...brilliant news. There was me thinking how I can justify coughing up another $1200 or so!

Tell the boys if they need a guinea pig, I AM THAT PIG!

Expecting dates for Letus Extreme Hd100?
 

Hi Jamon ...I did the same thing but Quyen just answered me " They are working on that" I tried to ask again asking if they have already expecting dates but he never aswered, Do you have another response from Quyen?

Thanks, I guess it would be a good combination....

Hey Alan,

I actually Talked to Hein (I hope i spelled his name right) and he said that he was actually playing with one not too long before I talked to him. He said that it was brighter than the stock Fujinon, I don't know if he was just talking but I wont doubt it, I love the Letus. I couldn't nail him down on a date but i will say he hinted before X-Mas so....As you probably gathered from the modular quote they are actually working on a relay that will be sold separately. The relay is probably gonna be around $1,000.

I came across the smear again yesterday. Will post examples. Worst culprit was my f2 nikon 105mm dc. When I used the dc function I could minimise or exagerate it. This could be vital information as to why it is happening.

As a side-effect, does the DC function move the plane of the iris blades forward or backward on the optical centre axis relative to the focal plane?

This might have some bearing on it if it does.

Every adapter will have some effect on the picture, you are shooting thru a diffuser.

M2 has less blooming and very little grain but loses a TON of light and the bokeh has a distinct and sometimes "fake" look, like it was forced in post

Brevis has very little blooming, loses very little light but can get grainy very fast, especially with CF3L. CF1L is a great diffuser but you will need to stack some ND's in front of it to get more DOF.

The Letus EX has almost no light loss but you get the smeary bloomy effect. It is on EVERY unit but it is situational. It is the easiest adapter to use.

Bottom line, know your unit and how to work around its faults. There will never be a unit that addresses all the issues, to fix one, you create another, it is just the nature of shooting thru a diffuser.




ash =o)

I'd be up for a HD100 Extreme, should it eventuate.

Sam

The HD100 version of the Extreme will be a modular addon for the existing Extreme. This makes the Extreme very versatile as it can be used now by threading onto a lens or when the HD100 module comes out, it can be attached directly to the JVC body.

I already built my own LetUs Extreme for my HD100...work beautifully. And I am not talking about adding the adapter to the end of the fujinon lens. I was able to get a adapter to connect nikon prime to the HD-100 body and then attach the Extreme to it...works like a champ!

EXTREME - NIKON PRIME - JVC
