35mm Adapter Comparison Table

Dennis Wood said:
The Brevis35 + flip (including internal power cells and 35mm lens mount) weighs in at 2.3 pounds which makes it the lightest flipped adapter system out there. Given that our rails system is solid carbon fibre (1/2 the weight of stainless and 75% stiffer) the weight difference looks better when rails are factored in. We've abandoned stainless in favour of the much better material properties of carbon.

Jared, the Brevis35 systems ship with internal rechargeable cells, and a charger/AC adapter as standard equipment...something not reflected in your chart. I'd also suggest that light loss figures should be quoted using a 35mm lens mounted (50mm f1.4)..as our .5 to .7 stops has been quoted. If you really want to be comprhensive on light loss, you should also indicate light loss at f2.8 and f4.0 as there is a huge difference between the Brevis using CF1Le and all the others listed. It's in the order of 3 to 4 stops faster by time you get to f 5.6. This clip illustrates http://www.cinevate.com/images/lightloss.mov

The other values you've quoted simply don't reflect real world use of the adapters. Light loss is something we've obsessed over particularly with respect to CF1 and CF1Le. Leny's light loss tests are the best that exist anywhere with regard to comparative light loss between the adapters.

Another major point not reflected is that a given Brevis unit can be optimized for both large and small cameras using our interchangeable imaging elements so that both get full frame performance across the typical lens range on everything from the HV20 to the HVX200. Given the optics differences between these cameras, anyone suggesting that an adapter system can provide full frame performance without the same modularity, is not telling the whole story.

Forgive the lengthy post, but the chart and sticky means this will be read a great deal..and accuracy is important.

Cheers,

Dennis - I overlooked this post somehow, I apologize. I'd love to include a more detailed section with light loss numbers with/without flip units, with different lenses, etc. I don't have nearly enough info yet though. I might make a chart with the data we have and see if people who've run well documented tests are able to provide the numbers we need to fill in the gaps. I'm not sure.

Same goes for the weights actually. It's been hard for me to find the weights with/without flip units/rails/lenses.

I'm definitely game for increasing the scope of the chart but I don't have all the data I need for fair representation. I'm also not sure at what point its complexity will outgrow its usefulness for the prospective adapter buyer.
 
Jared,
I've gone down this road before probably on this thread. Its going to be hard to put simple numbers in for light loss because the parameters are a little complicated and nobody's tests have been perfect, so I sympathise with your plight.

I could send you my numbers but others have had different results.

The numbers in the chart you have now though are unfortunately pretty misleading as they are based only on advertising and in my experience are plain wrong.

What is anyone thought of the best Adatper and Flip to use with the HVX200A W/ Nikon lens - attached to the M2 Matt Box, Rod and Base Plate? Need to order one by this weekend.
 
Just thought I'd chime in here...

I believe that once you purchase ANY of these adapters, if you give yourself enough time to learn the particular quirks of each, you'll be able to achieve the look you desire. And in the end, a shootout between all the adapters should reveal that they all basically look the same when properly used. Light-loss is really, I think, the major point of difference between these adapters, as I think they've all pretty much nailed down the "film-look" everyone is after. The differences are too small to mention, and come down more to user experience than the inherent capabilities of the units.

I own a Brevis (CF3L Diffuser), Minolta glass, and a DVX100 classic, and that baby NEVER comes off the rails. I have been able to get some really beautiful footage, and it has never let me down. It is also incredible in low-light situations, even with the more light-hungry CF3L, which has the most film-like bokeh of their interchangeable diffusers. I love it, just like everybody else loves (and defends) their own adapter purchases.

So, you really can't go wrong. Look at your budget, and don't forget to purchase the FASTEST 35mm lenses you can afford.

Be brave, and resist the urge to debate over minutiae - just go get some footage in the can!

Another issueto be considered is the lead times for shipping your order. I´m actually living a nightmare with Redrockmicro. Here´s my history:

37 natural days and Redrock still not shipped my M2!!!

The very day I made my order your shipping lead times site showed a 5 bussines days lead time for my current order!!! But I guess it only was Redrock´s best estimate as they state in their legals !

12 days from my payment, when I asked for my order status Redrock replied:"The M2 is currently backordered and the lead time for this is approximately 14 days."

15 days from my payment. Redrock Reply: We are looking at an approximate lead time of 10 days from today.

30 days from my payment. Redrock Reply: We have finally rectified our M2 part shortage and your order will ship early next week.

34 Days from my payment. Redrock Reply: We attempted to ship your package today, and it seems there is something wrong with the address we have on file. Can you please review the shipping address you have for this order and make sure it is correct.

In the next hour I sent again my adrress. Redrock Reply: I think I figured out where the mistake was in the address. The city was entered into the wrong place. It should ship out on Thursday. Sorry for the delay!

And in fact!!! Today is friday and still no news!!!

I wonder... If this happen with my M2 what could it be with a MicroMatteBox, a replacement part, accesories????

Browsing on Redrock´s forum there are several user´s sufering the same history!
 
are you happy now with you M2?
i'm ready to order, finnaly you give me hesitations
To save lux the better choice is brevis, and for quality it's redrock i hope!

no offense but you sound like a big baby. you entered the city into the wrong place and then YOU complain? heck, THEY should be the ones complaining. you messed up, not them!

Hey Leni - light loss on the chart is just based on the manufacturer's specs as Jack recognized. I don't see a better way to present it in a concise manner and you're right, people are always going to argue about it. This is just a quickie comparison. One of the benefits, I think, is that it shows how incredibly competitive all of the offerings are with each other, down to the dollar.

I'm happy to continue updating the chart until we reach something that everyone agrees is accurate...(ha ha, but I think we can get there) I don't think I'll have time today though.

I'm not sure what to do about the pros/cons rows though. Everyone has had different problems with one or the other. I think it should be there, because obviously none of these adaptors is perfect...feel free to post your thoughts as to a better way to present the pros and cons for any or all of these adaptors.

Jared, thanks for putting this chart together! One question I have about DOF adapters that may be something for pros/cons is maximum shutter speed parameters with each unit. This is certainly a BIG factor for my purchase decision. I know that the extreme reports it at 1/120. The others I can't say. This chart focuses on the sub 2k DOFs and maybe 1/120 is as fast as it gets in that prie range. For more coin the Letus Ultimate reports no limit on shutter. Does anyone know about others?
 
Ditto!

Ditto!

does anyone know which adapter will have the widest view, meaning you zoom in the least amount so you get more view of the picture?

That's a great point too. Of course it probably comes with a spiderweb of factors related to the camera you are using. But on average which adapter requires less zoom to frame out softs and vignettes. At a certain point you go beyond the sweet spot of the lens and loose the perspective you are looking for say with a 28mm.

Zoom needed and shutter are important factors.:dankk2:
 
Ok just found a post in another thread from Dennis Wood reporting a 1/250 shutter max by tuning (i suppose the oscillator) it for such. This is the Brevis.

Wow talking to myself here. Sorry everybody new to the forum participation , want to contribute but don't want to clutter. Apologies.

So as not to spread misinformation here's what was said in relation to BREVIS

"The oscillation amplitude and frequency are controlled by the onboard microprocessor. On MP.1 units this can be adjusted on the fly (as it should be) with a full rig via the adjustment port. Normally the units are shipped calibrated approximately to the usual shutter speed at 24p...which is 1/48s. It can be tuned to 1/250s if desired. There's a tuning guide in our owner's forum section that covers the basic procedure."

In response to Zarbel. I used the Redrock M2 for over a year. I loved the look, but fighting with the light loss was a struggle indoors, and frustrating. Then I upgraded to the Redrock M2 Encore, and OH MY, is it a huge difference. It's an amazing piece of equipment. I only lose 1/2 stop of light. I got over excited and shot a bunch of B-roll at 1/1000 shutter, and I could see the spinning disk in my footage. That wasn't smart, but at 1/120 or 1/250 shutter, I love this thing. To me, it looks better than the Letus Extreme. But the Letus Ultimate sounds like it is a better adapter from all the reviews. Never used it. Happy with the Encore though. I'm saving up for the Redrock follow focus. I rented it from a buddy, and it was very smooth.
 
i just spoke to a RedRock rep at CineGear in LA last week and he said that that EX1/3 users are having edge 2 edge sharpness difficulties due to the camera front lens elements. i know Letus created an Ancromat attachment to correct their issue, but RedRock doesn't seem to have an answer for this issue. has anyone here had this problem using the EX cameras with RedRock adapters?

Why not just get a DSLR? Would that be the same? I am new on this adapter and currently not sure whether to invest with the adapter for my Sony HDR-FX1 or just get a DSLR.
 
Because a DSLR has half the resolution of a camera like the EX1, has problems with audio and has half the adjustable parameters. Then there are the issues with moire and aliasing that leave it unusable with certain frequencies of patterns, like bricks, grates, plaid, canvas, etc.

I have a 7D, but it has a lot of limitations.

The AF100 'might' be the ticket, but we haven't seen one stress tested yet.
