Agree, I had dozens of manual lenses over a decade ago when not many AF lenses existed. Nowadays it's totally different. I'm not going to strain my eyes trying to focus, nor am I willing to have a...

Manual lenses is a very small market niche, especially those expensive Voigtländer ones. It will make happy a couple of people, most will only yawn.

I depends on the dogs color, hair, eye color. My Z6 finds the eyes of my white poodle, but with my black poodle it almost always fails. In fact it often fails to focus anywhere on the face of my ...

@MediumFormatLover -- FF sensor collects over 1 stop (2.34x to be precise) more light than APS-C, so using your numbers the ISO 400 on APS-C equivalent to ISO 936 on FF.

@DrewRick -- this is a very primitive way of looking at the situation.
When it comes to bodies, the sizes and prices are overlapping and the sensor size by itself doesn't add too much,...

@Josh Houser -- unfortunately, that site is propagating popular false beliefs. It says, "The amount of light your lens lets in will not change, only the depth of field or the "blurry part" of the...

@MyReality -- I was looking for smaller camera to complement my Nikon Z6, including the APS-C cameras and lenses. And the interesting thing you don't really find a better package than Sony A7C....

@MediumFormatLover -- no, you don't understand equivalence, you just demonstrated it in your reply. It's a total equivalent of 17-28/4 lens, i.e. you will get everything the same, the FOV, the DOF,...

@MediumFormatLover -- I thought people who don't understand equivalence don't exist anymore after so many years and tons of explanations. But then again, I just recently found a concrete person who...

Sony pretty much killed their APS-C line when they released A7C.

Unless you already spent lots of money on APS-C camera and lenses and don't want to change I don't know why would anybody choose to go with APS-C cameras and lenses.
This lens is approximately...

@Dave Oddie - the art works can be protected by copyrights. It's been long suggested that software shouldn't be patentable, copyright protection is what it should receive. But the current system...

@Upritbass -- Chief Judge Leonard Davis of the U.S. Supreme Court in the Eastern District of Texas has dismissed a patent claim filed in 2012 by Uniloc USA against Rackspace, ruling that...

Poetic? Not for those who involved in patenting. It's a tough work not to miss anything. You need to be very diligent describing the prior art otherwise your patent won't be valid.

It's a shame the companies are still allowed to patent software. It's no different from math, which cannot be patented.

the article says, "Specifically, it features a 70mm front filter thread"

Dog's facial expression says it was a good beer. 😋

Imagine an electronically controlled ND filter.

The longer the focal length the more difficulties have to be overcome. The optical quality goes down, the air movement smears the picture, ISO has to go high reducing the image quality, the size ...

70mm filter thread? That sounds unusual. I have dozens of filters but not one is 70mm.
