servo motor with linear actuator, very easy to control with regular RC car remote

At 18fps the shutter speed is 1/65, at 24fps the shutter speed is 1/86, and at 36fps it is 1/130

There's very limited options for zoom lenses with more than 2-3x zoom range. That's why I'd like to explore this further.

Hey guys, I was doing some math the other day and realized that when shooting Raw video in the 3x crop mode on my 5D the active sensor area is very close to 16mm format. I'd like to try an m42 version of the krasnogorsk meteor 5-1 zoom since m42 is easily adapted to EF mount. Are there any other 16mm cine zooms that could be adapted in this way?

or these (650w) 10pcs Ceramic Standard Medimun Screw Base Socket E26 E27 Bulb Holders With Wire for Hot Halogen Bulb (E26 10pcs) - - Amazon.com

these are $4.00 a pop, but they're porcelain and the ease of mounting is what appeals to me: Satco 80/2164 Medium Base Socket E26 Surface Mount Porcelain 6" Leads Sign Receptacle (lighting2lightbulbs.com)

because this lens has 3 different helicoids working in tandem, (because of close range correction) I used the lightest grease available (#10) the only thing with a lower viscosity that won't migrate would be a regular household white lithium grease (which I've read is appropriate for stiffer lenses or very fine threads)

I was successful in my attempt to dismantle, clean and regrease the helicoids. I put it all back together and it focuses perfectly from infinity to macro, there is just one sport where it's a little stiff I think this is when the CRC helicoid kicks in. may have to take it apart again and rehaul those threads with a lapping compound but right now it works well enough for my use!

OOH! thanks for the warning, definitely don't want to get branded by the cookaloris!

I'm pretty damn happy with this thing for $75.0p (used) i measure f4 (asa 800) from 10' away with full CTO through a 55" softbox with the interior diffusion kthe one that hangs inside plus the outer diffusion (so 2 layers of diffusion) this thing is gonna be really handy. As an added bonus the barn doors from my LOWEL DP light fit perfectly so this solves the problem of gel frames!

Hey guys, I found a great deal on some GODOX sl-60w today, they are a 60watt open face daylight LED with a standard bowens mount (kind of like aputure) I have a bowens style speedring for a 58" octagon softbox already, I'd like to purchase some other modifiers but I've never owned any other bowens mount stuff. The first thing would be some type of gel frame for CTO (to balance with my tungsten kit) do they make something that just snaps in to the bowens refelector? I'm also interested in some type of ellipsoidal attachment (so i can use it to fill a bounce card like we do with LEKO's) can you guys recommend anything? and maybe just some basic essential bowens specific attachments that would make a nice kit? (barn doors, lanterns, etc...)

So if I understand this correctly, if I wanted the same DOF as 2.8 (s35/aps-c) I would need to stop down to a 4-5.6 split (FF) ?

what method of construction did you use?

Hey guys, We're slow here at the shop where I work. (winter slump) I have access to a mig welder, drill press, some taps/dies and a band saw. I was thinking of fabbing up some little bits and peices that could come in handy for rigging. maybe start with making some wall plates that have an 3/8" nut welded to them that I can easily screw a baby pin or other receivers into? What are some other peices that are simple to make with the equipment I have listed?

Now that I've had a few weks to practice with this camera package, I have found that the 5D3 sensor is capable of shooting at much higher ISO with less noise than the 7D because it uses 3x3 pixel binning instead of line skipping. So a lot of the noise get's binned out in camera. This has allowed me to shoot deeper stops with the same lighting setups. It seems like If I shoot for 5.6 I have about as much DOF as 2.8 on a S35 kit. couple that with the fact that the HDMI out is a true 1080p it's easier to see critical focus on a monitor or EVF too. feel much more confident now. Thank you for your input
