Brevis 35 vs. m2 redrock adaptor

Rez, with regard to what you're suggesting, it would be worth exploring. However, I suspect it would be better to machine an interface between the 60mm macro lens, and the camera body rather than using all those adapters. I'm assuming you've already researched using the macro lens as a relay as I have no idea if that would work. The best thing to do, particularly if you own the macro lens, is to set it up on a test bench. An adapter can be represented by just a 24x36 frame in this setup, so all you need to do (sounds so easy doesn't it?) is get that frame focused on your cam's CCD's via the relay. You can email me if you need some help setting up an experiment or two.

So where's the shoot out.? I think that the SGpro should be included as well.. The owner is very nice, responded to my emails and the footage looks great. I have a February purchase date so window shopping now would be cool...

RGD... ever get to it? Can we include most of them... aside from the obviously out of price range movietube..

I like the SGPro too. Like I said, I'm up for a shootout. I've already made my decision on what to buy but I think this shootout would really help the DVX100 and HVX200 community. I'm eager to put my Letus35 Flip Enhanced up agaisnt the SGPro, M2, and Brevis35. Let's stop talking about it and just do it. I'm available next weekend, December 2nd or 3rd. Who's with me?

Oh great! Thank you for your detailed reply! I do know that Nikon sells just the F-mount mechanical ring for custom applications. I really have no idea how to do what you're describing in a precise manner, but I do already own the AF version of the Nikkor 60mm macro lens. But because the registers are so close between the Nikon F-mount and the B4 mount, that would probably necessitate DELETING the factory B4 mount on the camera, then trying to engineer an F-mount directly on the body.

There just doesn't seem to be a way to (cheaply) mount some kind of high quality macro lens to a B4-mount camera. That $5K+ Fujinon 20mm B4 macro lens seems to be the only thing on the market.

I'm with ya storm. Another interesting control would be to throw in the scneider 2x tele-converter. I'm really looking at that... I know it's not the same thing, but it would be possible to do some pretty cool things with DOF.
 
Hey guys -

Exciting news coming within a day or two - I have a small but extensive test shootout that I have been performing with the Brevis and the M2 for the past few days. I tested light differences, overall ergonomics, DOF differences, everything you kats want to know about the differences between these two heavyweights- Post coming soon..

In the meantime, P+S, Movietube, Letus man... if you guys want to donate your adapters to my cause, I will glady do a shootout... hell... it's better than working..

: )
 
Let's just say they both have their fair share of pros and cons. It's all going to be about preference. Review coming within a few hours. Just wrapping up the compression on this video comparison I've been editing for all you guys.
 
It's very nice of you to take this on. can't wait to see the results. I'd love to see more adapters get worked into this too.
 
yeah RGD. Thanks so much for your hard work. I keep playing with my equipment and my day job is suffering. hahahha. (so don't get fired on account of us.)
 
If I had a proper chart I would have done it.. I didn't want to print one out.. Check the Unicorn scaled clip, that will give you a good idea of detail..

I figure it's pretty much down to preference at this point. We've all seen enough images from the more afforable SGPro, Letus, M2, Brevis, and the DIYs to see that they create great images, at least on the DVX100.

My curiosity is how this Letus will hold up to the HVX200 1080/24PA. How much grain will be seen and will you see it moving? Other than that I love what I'm seeing with it and the DVX. RDG, I'm in for lending my Letus to the cause. What area are you in?
 
thanks for the shootout, in my eye the Brevis wins. I had the M2 but sold it because the motor was just way too loud, I could pick it up from 10 feet away, others didn't have this problem but I did, even after tweaking. I ordered the Brevis and I pray the motor is less noisy. anyone else with a brevis that can comment on the motor noise?

gota say the brevis is way bright!! compared to the M2. Anyway thanks for your hard work.

\v
 
I've been kicking around the idea of getting a 35 mm adaptor, looks like the Brevis wins from your footage (For which, many thanks).
Will havt to keep an eye on exchange rates and bank balance in the new year!

I found the test very confusing ! One minute were seeing the M2 at f11 the next were seing the brevis at f1.8 on the same shot ?
Also did you not have any more ND filters, I don't see the point in seeing a really over exposed image as was the brevis most of the time. If the M2 is that dark then show it to be so but I would never shot with the brevis so hot.
Please can we have a properly exposed test.
You mention that the brevis was very noisy when tilted vertically could you record some sound evidence of this perhaps ?
Cheers
 
you might have a difficult time recording the sound from the brevis. as designed, it doesn't register in the cam's onboard mic, or even my external Okatava during shoots. The only way would be to basically touch the mic to the unit, then bump it up in post.
 
Hi Rgdfilms,
Great test. I still think it would be better with a controlled environment. This way we can really judge from one to the other. I just got my M2 this past week, and would have loved to have this test prior to ordering it. (by the way I ordered on the 15th and received it at my door on the 24th) I didn't realize how much light it looses. Though I'm super busy right now, would love to sit down with you one day and take a look at both adapters and do some test. (also you may be able to help me set mine up a little better that what I have it setup so far. I will be doing a hard mount as soon as the step down ring and the male to male adapter shows up.) I think the best thing to do would be to be in a studio. (ie. my empty room or somthing like it.) have controlled lights, set up both cameras at the same distance. Get a proper focusing chart. (I wouldn't mind springing for one myself) and then rather than providing moving pictures, take stills and post those up side by side with the same f/stop setting. This would be a great time for anyone with the LETUS and the SGPro, to bring their cameras, mount them all together and do the test at the same time.
What do you think?
We could also weight them all.
And take to still photos of the set up so everyone can see.


Also. what does this mean?
"Since I decided to not attach the rail system to the M2, it only took a minute to screw it on the front of my HVX"?
did you have the M2 attached with a hard mount also. screwing the lense to the M2 etc....?
Why color correct the shots? (wouldn't it be better if they were not CC.?

Thanks for the shootout, RGD.

As for noise with the Letus, you barely know the thing is on. That's why there have been a couple times that I have forgetten to turn it one and only realized it once looking at the footage on a larger monitor.

siniarch - This Saturday?
 
Wow. Nice job. That Brevis sure is bright. Might be handy. I'm having issues with using my M2 indoors just because I don't have a good light kit. It rocks outside, but I could use more fixtures (which I can't afford) for indoor stuff.

Anyone know how the SGPro stacks up, light-wise? Their footage looks nice, too.
