There is a perpetual online discussion amongst measurbators about “equivalence”.
Equivalence is a very real phenomenon which can be predicted and measured. The idea is that when comparing cameras with different sensor sizes, smaller sensors tend to have greater depth of field at “equivalent” focal lengths.
Why “equivalent” focal lengths? Ok, it gets technical pretty quick, but rather than bore you with esoteric technobabble, lets just look at some images. (Photography is about making images, right?!) If you feel that the differences are drastic, then by all means read on. But if none of these images strike you as dramatically different from one another, just know that you can safely ignore anybody who ever mentions “equivalence” or “equivalent apertures”. Because they’re either trying to waste your time or sell you something. (hopefully I’ll have saved you from the clutches of some forum troll)
Here they are:
This is what the war is about. A mountain of a mole hill, idn’t it?
True story: modern cameras are racist. Most slide film, with it’s high contrast, was as well. “Kodachrome has great skin tones” was only true for white folks. Digital has actually been better at this for at least 10 years. But not at high sensitivities, and not always with video. And video is tougher to correct in post.
So I happened upon an amazing piece of software for basic adjustments and manipulation of photos on Android devices, called Photomate R2. It’s a lot like the ACR/LR engine, perhaps with a little less refinement. But it handles true raw files, and it’s the only Android app I’m aware of that does so.
So I’ve got that wrapped up.
What I haven’t figured out yet, is an app that will allow me quick manual controls of the camera actually in my phone. Something that will simple direct control of things like exposure/ISO/aperture/WB.
Imaging Resource/SLRgear has D4s test shots up already. Is this the new Lord of Darkness? See for yourself! IR brilliantly gives you raw files from their lab test scene for damn near every digital camera ever.
I’ve just had my first absolutely awesome experience with the Nikon USA repair department (all previous ones having been abysmal). They did a bang up job (for a price!) of bringing my many times dropped 70-200mm VR (V1.0) lens back to spec. And the proof is in the images!
This was shot with the 70-200mm, a TC14E, and a crappy Tamron 2x extender, on a D7100 (for a grand total of 840mm equivalent in 35mm) and it STILL looks good (in my opinion)
I’ve never personally sent a lens in for repair to Nikon–only bodies. And we all know how bad that went!
Perhaps I got lucky? Or they do a bang up job when it’s on my dime? Or maybe Nikon actually has some good test gear for lenses, but not bodies? Time will tell, since I still need to send my 17-55mm lens in!
I just discovered something awesome. Maybe this was obvious and everybody else knows about it, but just in case you don’t: I used a sensor swab to clean a DSLR mirror.* Really wet, really gentle. And now REALLY clean! AF even improved!
*Try at your own risk! I am not responsible for any damages to your camera.
I’ve been complaining about being hassled at concerts for a long time. Especially when they’re expensive ones. I’m incredibly discreet with a DSLR, and others are taking pictures with their phones anyway…why bother me?
