I had done all those checks, and it was off. I went to B&H and checked their floor models. The front tripod leg was lower in all three of the Systematic series 5 I tested. It was not lower in the ...

Glad it worked out

Thanks for pointing out the need for cables. Run in the mill usb 3.0 won't even deliver 1 amp. From my measurements you can see that's just not going to cut it. I didn't make charts because it ...

As others pointed out, converting an existing lens design as-is would be equivalent to using an ftz adapter. There is, however, a "middle ground" between a brand new design and an adapted version ...

@RobDunf Yes, absolutely more hot and dense than we can imagine. The science gets a bit uncertain at the instant of the big bang, but a second later it was still two million time hotter than the...

If you'd like to be more precise, the universe used to be hotter and denser. Since the big bang, it has become cooler and less dense.

The big bang didn't happen in one place. It's space itself that expanded. It took "first light of the big bang", known as the Cosmic Microwave Background, billions of years to get "here".

I suspect it was something wrong at my end.  I was going to try again after logging off and logging back in but I literally fell asleep and woke up at 9.

Had the same problem. I fell asleep and ended up ordering at 9am this morning. I guess I'll receive it by 2024 :-D

Yes, this is true with some additions. The image shot with the TC has more noise and motion blur per pixel. However, it also has more pixels. If you were to downsample the TC image, the blur and ...

Good to hear.  What are you shooting? Tell me how you it goes.

With a Z camera in DX mode, you see the cropped frame filling the entire viewfinder. This makes it easier to see your subject and compose the frame. In addition, the camera matrix meters the ...

The 70-200, but that's just me and what I shoot. I use the 70-200 when I'm shooting events (indoors and outdoors). I take my 2x and 1.4x converters with me in case I end up in a situation where I ...

Are you suggesting that lens correction is applied when metering? Or that any difference in metering is caused by vignetting, which will be corrected in the file and hence won't be seen when ...

My Z f2.8 70-200 is ridiculously sharp all the way to 2.8. My F mount 70-200mm f/2.8G can't touch it. It is so sharp, I lose almost nothing with a 1.4 TC. Even a 2.0 TC gives excellant results, ...

Vignetting and transmission loss are two different issues. Vignetting is a gradual darkening towards the corners. Transmission loss affects the entire image. As you mention, lens correction will ...

Thank you for reporting back.  I am not really suprised it is 11% dimmer, but like you I am suprised that it would have such a noticable effect of ability to focus. When I have a chance I will test ...

Touche.  You could add habits that are "bad" for you like smoking ($2,000 /year) or compulsive gambling (+$10,000/year).

I agree that is much more accurate, just a little more involved.
