sgpro or brevis

i chose the sg pro after seeing those 50 stills and a couple others i can't remember the names.for me bokeh, ultra cleane footage, along with sharpness impacted my decision.should be recieving mine next month.and like logic 108 if i want to sale i'm sure the resail value will be no issue.
 
Has anyone really compared the M2 and SGproRev2/3? I'd like to know/see some comparisons with both using the same glass.
 
Log, for the record, we've had PL and OCT19 mounts for the last six months or so. In fact, we've already introduced the second revisions of both :-) I could be wrong here, but I believe the Brevis is now the only adapter out there that offers quick and easy external micro-collimation (better than +- .001" placement)of all of our lens mount types, SLR or cinema. Cinema lenses are so finicky with respect to flange-to-film distance, we pretty much needed this feature to guarantee perfect performance with these lenses.

CF1 can be used in both the HV20, and HVX, but CF1L is not a good choice for the HV20.

the performance imagewise between the two are very close. nearly identical. The differences are more in the "look" you like better. the brevis renders light in a certain way, the Sgpro renders light in a certain way. then theres a couple of differences in the physical form. the sgpro is a hardmounted rail system. its sturdy, and heavy.... but sometimes heavy is good. it adds weight to camera movment. the brevis is lighter, and is a tad easier on the handheld stuff, gives a lighter airier feel to movemtns. though you VERY easily can do handheld on a Sgpro. i know ive been doing it for 5 days now on my current shoot. at this point these machines are hitting their high performance marks. so they are are more kinda similr than different. it really just personal preference now.
 
I read something about the Brevis not being able to work with fast shutter speeds compared with the sgpro. Can anyone expand on this?
 
With the new adjustable motor you can get to 1/250th on the Brevis with fast lenses but beyond that you will see grain.



ash =o)
 
oh yea, the shutter speed thing, yea, on spinning adapters, like M2 sg pro, faster shutterspeeds are a little easier to attain.

Define faster shutter speed.
A movie should NEVER be shot at under 60, because the motion blur looks like crap. If Brevis can't work with 60-120 in shutter speed, I'm afraid it's a no go for me.
 
60-120 is not an issue, however 1/250s is the highest we test with. Most of our shooters tend to stay in the 1/48s range for 24p shooting. Timur is right though...if you plan on shooting over 1/250s consistently, until our polymer imaging elements are released, use a spinner. These elements will allow use of the Brevis in static mode for unlimited shutter speed use. Spinners will still see grain as you increase shutter beyond limits (determined by light levels, lens speed and aperture), but they will show a rotating mask of semi-circular lines. The only safe way to use high shutter speeds is using a static adapter (and you'll still need to watch for grain masking), or use the bare cam and intercut for these shots.

i think you can easily hit 1/120th with the brevis. ive sen aram do it. if i ever need 1/1000 a sec i use my Go35. static adapter. :) sgpro will hit 1/250 MAYBE 1/500 with real fresh batteries. but then sometimes the grain gets frozen and it looks weird.

Also if your persoanl aesthetic is REALLLY fast shutter speeds, i reccomend a static adapter altogether. Movie tube for example. its shutterspeed agnostic.
 
But I can shut of the Brevis can't I?
It's unnecessary to have a high shutter speed when doing dialogue.
The only time it's good and shows of the crystal sharp images, is when something is moving, like in an action sequence. If that sequence have so much movement, I will not be able to see so much of the grain... at least not if I clean it before :P
 
Anything faster than 1/250 is pretty fast. I wouldn't shy away from shootingat speeds slower than 1/60. 1/48 is used all the time when shooting at 24fps.
 
well, for me it's 1/50 due to the framerate of 25fps with PAL.
But if you start going under, you'll get a really awful looking "videolike" motion blur that really shows that this isn't film, it's video.
Sometimes it almost feels like someone used a consumer camera for family memories and shot a movie, when the only thing they need is to use faster shutterspeed.

When Michel Mann did Collateral I got that feel as soon as they started to use video. The motion blur looked so awful I could puke...
 
G, you can shut off the Brevis...and that's exactly what the polymer imaging elements would let you do. Even with an imaging element that does not require movement (and therefore the same as a static adapter) we'd expect most users will still use it moving to add a bit of insurance to the cleanliness of the image.
 
I recently got my REV 3 SG Pro. I think it's phenomenol. People here often say one isn't better than the other, blah, blah, it's a matter of taste. That isn't necessarily true. There are some cold objective considerations: Sharpness, grain, light loss, bokeh, ease of set up, build quality, alignment, and customer service.

For me, someone who was brought up on ENG and film cameras, the extra weight (8oz ?) of the SG Pro isn't an issue.

What sold me was the sharpness, lack of grain, alignment, build quality and responsive customer support. Very few adaptors out there can handle the rigors of filmmaking beyond the hobbyist. SG Pro has an industrial build that I feel confident with. The image I found as sharp as a PS (for a fraction of the price). The lens mount is a precision build and has no flex etc. This is important, especially when torquing a follow focus on a sticky lens. Ideally, I feel a remote focus is the best way to eliminate the jiggles that virtually all of the adaptors on this site suffer to some degree. Red Rock, hurry up.

SG loses a bit (about 1/3 of a stop) more light than Brevis. This is the price for a great bokeh. However, Brevis' new CF's I hear give an excellent Bokeh - not sure what the light penalty for that is.

The last item I forgot to mention is dust. I find the seal on the SG Pro to be excellent. Dust on a GG is a pain in the ass, causing you to disassemble the entire unit. WIth my previous adaptor, after having to do that 3 times in one day, I sold it and ordered an SG. That to me was the deal breaker because anything that stops you from shooting has grave consequences when people are waiting around and getting paid.

I also love the SG's battery design. It's external and takes double AA's. Which means I can use rechargeables or in a pinch go to the corner shop and get some AA's. I use velcro and just stick it on the side of my adaptor. Very cool.
 
Yeah..I can't wait to see how the SGPRO does against my Letus FE. But it's great to hear that the GG is sealed against dust vs my Letus does have that problem due to the amount of mirrors involved.
