Reviews / Re: NIKON Releasing a Medium format DSLR 50MP

Hopefully someone with better attention to detail, too.  In removing the left side of the camera, the lens release was also removed.  A buyer would need to think carefully about which lens to mount first...

That might be a feature not a bug. A MF entry by Nikon will need a new lens lineup. The article mentioned that Nikon has a patent for exactly one MF lens. If there is only one lens, no real need to take it off after you mount it.

A question to the more scientifically competent than I:
So, DSLRs have bigger lenses than rangefinders or other mirrorless cameras because there is a bigger distance between the end of the lens' flange and the sensor. Would it be possible for Canon or Nikon to make a mirrorless medium format camera that could use their existing stock of 35mm equivalent DSLR lenses?

jrista,

If you wouldn't mind, I'd love to get a walk through of your post processing. You mentioned using DeepSkyStacker and PixInsight to boost the DR of your files. I'd love to get a a step-by-step look at what you do. Thank you!

Third Party Manufacturers / DXO uh-oh?

As DXO has given a near perfect score to the D810, they may have painted themselves into a corner. Their proprietary scale doesn't give DXO much room to heap hyperbolic praise on the next Nikon release.

My read was that the supposed camera has a fixed - not interchangeable - lens. If the curved sensor design allows Sony to make small, high quality, fixed lens cameras for less, that seems like an interesting value proposition.

Interesting. You could glue gold leaf (the imitation stuff is only $5-7 per book) on the aluminum blank you cut to get a warmer light.

It is the 22 inch high output white beauty dish by Paul C. Buff fitted with the 30 degree grid. I turn my apartment into a "studio" by moving all the furniture out of my living room and into the hallway and setting up a continuous paper roll (fashion gray in this shot). While it may look like I lit the backdrop, it's just spill from the beauty dish -- I don't have enough space for the model and the lighting to be very far from the backdrop.

A single Einstein fitted with a gridded beauty dish. (I edited out the catch light from the crystal globe in Photoshop.)

A traditional planar sensor will only have part of a properly focused image out of focus. The advance of curved sensors lets a photographer have an entire properly focused image blurry.... Progress!

Or something.

I'm going back to the Big Island this August. I second the 24-70, it's what I will use 90%-plus of the time. You might consider the 14mm, especially if you make it up to Mauna Kea as you can capture some amazing pictures of the Milky Way.

I post here mainly because I enjoy helping people, sharing knowledge (I enjoyed teaching medical and graduate students, and I rather miss teaching), and good technical discussions in which I can both contribute and learn from others.  I'm not sure why you post here, other than trolling and posting incorrect facts and misinformation. 

Apparently you're unwilling to put your reputation on the line.  Interesting, although I can't say I'm surprised.

Sometimes poster / long-time lurker: I find Neuroanatomist's posts enlightening and, often, funny. Not that this relates to the D810, although not much in this thread really does.

You can mix-and-match Einsteins and 600-RTs. Mount your ST-E3-RT on your camera and connect your Cyber Commander to your camera with a PC sync cable.
