Review of Quyen Le's Letus35

Graham Bernard · September 14th, 2005, 12:47 AM

Now, Quyen, please explain the meaning of AERIAL?

Quyen Le · September 14th, 2005, 01:03 AM

As far as I learn, I understand aerial image is thru the lens, nothing blocking, everything is in focus. I don't know if anybody have a better definition of this word. Thanks.

Just got my adapter today and even though I haven't tested it with a camera yet, I can make a few comments.

Everything is very well built and SOLID. Except for the lack of cosmetic values like fancy logos, it feels like something that came out of a factory. The image on the GG is excellent (I'm using a canon fd 50mm f1.4 lens). Also, one of the main points of contention on this adapter is the noise produced by the ... errr... vibrator? I have to say I was very skeptical, because all the vibrating mechanisms in my cellphones make a lot of noise. The one on the Letus makes negligible noise! If you hold the adapter close to your ear, you'll hear the vibrating noise. If it's, say, 8" away from you, then you'll just feel the vibrations on your hand but that's it.

Overall, very impressed and will try to post a demo video soon.

Thanks

It isn't a particularly poignant example of the capabilities of the adapter, but we filmed this little *ditty* (thanks Bill) in its entirety with it:

Enjoy.

Hah, pretty funny.

Michael Maier · September 14th, 2005, 10:10 PM

Really Funny.

Wayne Kinney · September 15th, 2005, 05:52 AM

Hehe,
Watched that like 5 times, pretty funny!!! You certainly dont see any grain or flickering from Quyen's adapter, image looked great.

Bill Porter · September 15th, 2005, 10:43 AM

Very funny. P.S., it's "ditty".... Diddy is a producer from New York who just changed his name again.

Craig Bellaire · September 15th, 2005, 05:05 PM

OK anyway we can get maybe 30 sec to one minute of DV footage with the adapter. Yousendit.com can handle it and one minute would be about 250 meg. Also what kind of GG are we using in this? Plastic? Or maybe the 1500 GG glass from Thorlabs? Just wondered...Thanks

Wayne Kinney · September 15th, 2005, 05:19 PM

Craig,
Some raw DV footage uploaded would be great! I beleive the GG is a microscope slide ground with 600 grit silicon carbide.

Thanks,
Wayne.

I just got my Letus35 and I must say I am deeply impressed with the build of the thing. Syringes? Microscope glass? Nah, it can't work! Well I have not had a chance to strap it on the xl but with my 85mm 1.8 on it you can see the grain all dissolve with the flip of a switch. I got it anodized so it looks damn slick. I'm waiting on my step down ring and i'll be takin' it for a spin tomorrow. I buy a lot of stuff and this may be some of the best money i've spent.

Below is 3 seconds test of HD clip using Letus35 and some modification by Obin.

Thanks Obin.

It seems like we are all in the running of delivering the first serious test footage. As pretty as it all looks until now, pretty doesn't bring much when you're preparing a difficult shoot and you have to know exactly what the strong and the weak points of the adapter are.

I know it is in a different price league than the p+s adapter, but that shouldn't change our critical attitude towards it. I got the feeling this small fellow deserves better.

Marius Luessi · September 16th, 2005, 05:16 AM

We will be conducting our own tests shortly using the LetUs35.
As far as the two recent clips are concerned, can it be identified where the SPECKS are comming from?
Ben and Obin?

Ben, in the RAIN FALLS ON UMBRELLA scene there are some specks/dirt(?) visible. Same with the most recent clip from Obin. Is this coming from the lens that is attached to the LetUs35 or the LetUs35 itself?

Curious...
