Minolta MD and MC Lenses
Concerning your "Orange-X", which optical design is it? That would help when recommending lenses to others on here. Is it an MC or MD? ROKKOR or no ROKKOR? The orange ROKKOR-X only designates that it was sold in North America. Does it have…

I am only speaking of optical (light path) designs of which there are four. There are many configurations of construction, markings and coatings included in these designs. At present count there are 13 sub-variations without taking into account lens…

@DrDave More than four optical designs? Can you share your source? I am curious where you have heard this. There have been different ways that the casings for the front and rear groups have been built during the run of various optical designs, but I…

Concerning bokeh...I did a test with most of the standard (45, 50, 53, 55, 58 mm) Minolta SR mount lenses (and two M39 mount ones). You can see them here. https://drive.google.com/open?id=0B14hN10qvwXjRENyV2Q2M2hLNWc

There were other diagrams of the first design that were floating around in early Minolta literature that turned out to be incorrect. They are believed to have come from the marketing department and did not represent the actual design. I disassembled…

Here is a scan from a Japanese book called "Minolta Camera History". It shows the optical diagrams of the four versions.

Minolta MD and MC Lenses
Which MD version? There were four distinct optical designs for the SR mount 50/1.4. The MC ROKKOR-PG (or for North America MC ROKKOR-X PG), the MD ROKKOR (MD ROKKOR-X) with the 55mm filter thread, the MD ROKKOR (MD ROKKOR-X) with the 49mm filter thr…

GH4 Firmware 2.3, V-log for $99, Epic Panasonic marketing fail
@BrennanK Got it. I have edited in Avid for years on Windows. Love DNxHD/DNxHR. I have a Shogun and record in DNxHR. Sorry you can't.

@BrennanK Why the step to transcode to DNxHR? Why not just work with the file in ProRes?

Geez people. Someone tries to help others, and you are all over him. @paglez If something has been available on a camera since its release, it can still be a "hidden feature". (Some less hidden than others). @joethepro Many peolple get con…

@touviere7 I find the GH4 to be a much more ergonomic camera to use. The GH2 seems tiny to me now. I assume when you focus, you have your hand on the lens. This is where the balance comes from. I have no problem using my thumb on the Fn3 button when…

@touviere7 As @h20tara stated, read pg.107 of the "Owner's Manual for advanced features". You will see which button is the default for this feature, the Fn3 button on the back of the camera. It can also be programmed to another funct…

@digitalflaskpost That was beautiful. @jopereira Widescreen is great for many films, but some films need 1.85:1 or 1.77:1 treatment because of the subject matter. Most of the shots in his video are of a single childs head. There is no service to th…

@dlzn Minolta didn't make a 28/1.8. Did you mean 28/2 or 28/2.8?

Atomos Shogun 4K recorder
One thing I have noticed on the Shogun. When recording in the GH4 Luminence Range of 0-255, the waveform on the Shogun shows super whites and blacks. When brought into After Effects, all of the range is there when the footage is interpreted as "…

If you are shooting in 0-255 mode, the histogram seems to show 16-235 as darkest and lightest limits. That is, 100% zebra will show at 235 where it should show at 255 when shooting 0-255.

Available when DMC-GH4 OR DMW-YAGH are connected... I think what that means is that the limiting factor is that you have to have an Atomos product connected for that feature to work. You can come directly out of the camera or through the YAGH.

I love my GH4. My grading is not the best in the world, but I used the GH4 for this short film (45 secs.) for the 2014 Fantastic Fest bumper contest. I was using a Metabones Speedbooster, older Minolta primes and anamorphic front lenses (SLR Magic A…

Since you are dealing with a video file in the h264 codec, no matter what the bit depth 8 or 10, you really should try to get as close to the final look that you want "in camera". The reason Alexa and Red users record a Log profile is beca…

@maddog15 You have to remember that when RECORDING at 96fps, the bitrate would be a max of 104Mbs if it is max 26 Mbs during playback at 24 (23.98) fps.

@Azo I will be getting my GH4 from B&H Photo on Monday. I plan on doing greenscreen tests comparing my GH2 with the GH4 when it arrives. Will post results when I have them.

@rNeil @AdamT The reason you would want to shoot "full-range" (0-255) is because there will be more discrete levels of luminance within the camera's dynamic range to start out with. If you plan on grading in post, this gives you more …

The Blood Moon over Texas on 4/14-15/2014. Panasonic GH2, Minolta 600mm f/5.6 Tele Rokkor-TD, Minolta 200-L 2X Teleconverter, Fotodiox MD to m4/3 Adapter. The phases overlap because I had to expose for the dark and light sides seperately.

Black Magic URSA - first modular camera, now from $4995
@bwhitz Really, you think that the budgets of films are ballooning because of unions? Have you ever worked on a major motion picture? As a crew member (and union member), I can say that the number one thing on your mind is speed on a set. On the qu…

@driftwood I downloaded your test, and wow, it looked great on my calibrated Flanders CM250 OLED grading monitor. It's resolution is only 1920x1080, but my Blackmagic Mini Monitor card can send just the center of the image to the monitor. This …

SLR Magic 2x ANAMORPHIC lens
Sorry, the test was to show the extreme of the bokeh, it is focused on the chart as best as possible using the adapter's ring and taking lens. Yes, 1.7 is too wide open for an actual shot.

SLR Magic 2x ANAMORPHIC lens
@BurnetRhoades The angular bokeh (i.e. diamond shaped) is being created by the adapter, not the lenses. Here are three images using the same Minolta lens. Minolta MC 50/1.4 at one click closed (1.4/2 split) and five feet from the focus chart. The fi…

SLR Magic 2x ANAMORPHIC lens
@vicharris I was not saying that the Anamorphot did not work with longer lenses, it does. What I was saying is that the bokeh (especially for point light sources) is odd to me. Do you get the same results as I do in the examples that I posted, or do…

SLR Magic 2x ANAMORPHIC lens
Thanks @BurnetRhoades. The Anamorphot has proven to be great for wider lenses, but I am still working on adapting projection lenses for close-ups. I have found that the bokeh of longer lenses with the Anamorphot is quite odd. See the earlier tests t…
