I don't know brother but Phil started this thread weeks ago, and there are people on here waiting, salavating like their very creative lives depend on it. Its kind of...I don't know annoying...like damn if you don't own one get one and shoot something. If you don't like it sell it and get a different one just because I like the Brevis means squat, some people don't like the M2 but DP's on 24 sure liked it.

Hi Phil, did I miss out something ? I see only one picture in the page2 ?? or you are still working on this ?

many thanks

If these three all use a 36X24mm imaging area, then there is no issue. Just checking.

Can anyone say why it necessary it to use 36x24mm over 24x18mm (such as what the RED CCD sensor uses?)

all done. hope at least one person finds it useful!!

Best,

Phil

P.S. Watch Channel 4 this friday at 1930. My first doco for the insider goes out. partly shot with the M2

Hi Phil,

Not getting anything from page 6 onwards...

Been really looking forward to reading this though - its a tough choice!! Anyone know if there are any adapters avaliable in the classifieds section? I'm not allowed in there yet!

Thanks for your work on this though Phil, and ill remember to tune in for your documentary!

Jim

James Collinson January 28th, 2007 03:59 PM

Aww crap, just remembered im in New York this week... ill have to get someone to tape it!

Phil Bloom January 28th, 2007 04:03 PM

Do James! It should be available on Channel 4 on demand too.


Check again now...it was probably still publishing. You were probably the first to check!

Dear Phil

Nice review. Thank you for all of your efforts.

Dennis Hingsberg January 28th, 2007 06:46 PM

Great work Phil, nice to see the finished report!

Looking at the stills you provided it becomes clear that with the Brevis you gain 2 stops over the M2 and you gain 1/2 to 1 full stop with theSGPro over the M2. It seems there's been some speculation as to the amount of light loss by the M2 - now we know for sure!

My favourite image from all the stills you provided is the SGPro 50mm set @ f4 and camera set @ f3.4.

To me this still looks most natural and life like. I have to be honest and say that the M2 also pleases my eye with much of the same natural color reproduction. Although not "exactly" the same I find the SGPro and M2 stills closest to one another and the Brevis images most different from the two.

The Brevis images seem to have a disturbing amount of more color or saturation? It could be a simple matter of preference I suppose.

One question: Why was the field of view wider with the SGpro ?

Thanks, again great work Phil!

Greg, I think you are talking by the elbows. Please dig the post where I praised the G35. I actually always criticized the hype with no product and I was actually right. Where is it now?
About the M2, it makes good images. If you don't analyze it on a real monitor it's hard to catch the lack of edge to edge sharpness. I was basing my opinion on what I saw online. Now that I have used the M2 extensively I see the real performance and I can and have the right to criticize it. About the Brevis and SGpro I'm just basing it on what I have seen online and on the laws of physics and I clearly state that on my writing. I never claimed to be an expert on Sgpro or Brevis usage. Who said that was a review? Yes, it was a review of the M2 which I have used several times on real world shooting. About the Sgpro and Brevis, it was my personal opinion. So what's your problem?
By the way, the ugly grain pattern I saw on the Brevis high shutter clip wasn't compression artifacts, but whatever. About not adding strain to the lens, I never said it adds strain to the lens. I said it adds strain to the lens mount! Quite a different deal. Of course, you wouldn't know it, you use a fixed lens camera, right?

Dennis Wood January 28th, 2007 10:13 PM

First, of all, thanks for putting all that work into your review! Is there any chance of grabbing similar shots using CF3, and your new adapter with new drive/Nikon mount, and adding them in? It would be a great comparison shot if you can reproduce at least the framing again. I'll fire one out to you....you'll like the bokeh.

Phil Bloom January 29th, 2007 12:27 AM

Definately Dennis. Would love to try it out.

With regards to the warmer tinge to a couple of the Brevis shots I think that is more to do with some of the shots being a tad over than the Brevis itself making it look warmer. It's only on the F8 setting that it looks warmer, the other adaptors were well under on that fstop.

Phil Bloom January 29th, 2007 12:33 AM

With regards to the field of view being wider...the m2 wasnt that well set up and we zoomed in a bit more than the others as we could see the motor a little. With more time we could have got it a bit wider. The brevis is zoomed in the correct amount to get past the vibrating GG edges and the SGPro actually needed to be zoomed in a bit more as there was a bit of vignetting. But it still is a bit wider, best if Wayne could answer that! Wayne?

Dennis Hingsberg January 29th, 2007 06:29 AM

Thanks Phil for your comments. With a little tweak in post I was able to tone down the brevis image down to where the others were - or alternatively tweak the other two a little to where the Brevis was.

Good stuff!

Ing Poh Hii January 29th, 2007 07:19 AM

Thank you Phil
 
Thank you so much for your quick review and dozen of images.

Now I am in a deeper loop of making a good decision.

Your test has just confirmed what I have been wondered long time:
SGPro is good for outdoor due to the way it handles midtone & exposure better yet Brevis is just the clear winner in low light or indoor situation.

I love the nature light & exposure of SGPro yet I love the versatile and flexibility of Brevis.. I disappoint to SGPro can't make the setup faster with flexible len mount (as I have both Nikon & Canon len) yet I regret Brevis can't keep the explosure & color as nature as possible...

All are lovely products but I have spent too much money over last two months, perhaps I have to clam down myself for another month before I decided to buy in both of them.

Any chance Wayne & Dennis can work together so that Wayne's achromat can fit with to Dennis adapter to achieve greater edge-to-edge sharpness ? Phil, what is your thought in this ?

Thanks a lot again for your lovely review.
