I intend to pair the R7II with my 100-500. Don't think much else would be needed for me.

Show me a 400 mm f/4 lens that has a front element less than 100 mm in diameter and I'll show you a 400 mm lens that is smaller than...

4.0 is really sad…. Back in the days I wanted this EF 17-55 2.8 soo Hard…
This plus IS would be a premium Apsc lens! They could do it...

I know from my own experience that even a "slight" modification of a product, in, my case, replacing a belt-drive with a chain -drive...

No, a speed booster does the opposite, got a bigger image circle of the lens and concentrate it on the little sensor. Crop sensor gets...

Nikon is getting lighter and smaller telephotos reducing image circle and correcting vignetting on processing. Just go further and you...

What do you mean by "reducing the image circle"? That is what a Metabone or Meike speed booster does. That is why you have to use a FF...

What lighter and smaller telephotos does Nikon make for their crop cameras? They have done their best to make lighter weight ones for...

So you don't understand optics and lens design, but you know more about marketing lenses than camera manufacturers? Lol. In the heyday...

No manufacturer makes them cause there's no profitable market to do that, but integrated teleconverters are showing that you can squeeze...

Test what? Just because a smaller sensor crops away the outer portion of the image circle doesn't mean a telephoto lens could be made...

Just get a lens and test.
You can put an inferior diameter filter without vignetting or open more the diafragm without softening the...

Yes, but I said properly understand. Clearly, you don't. Just because you prefer 'keeping the same FOV and exposure and letting the DOF...

Sorry, but no. You can argue with physics, but you will lose. Every. Single. Time.
There is no 'unused diameter' to remove. With...

id rather the 40 2.8 be resurrected for RF. i'm in love with its optical qualities. if canon can play with the EF 50 STM and repurpose...

I love my beast of a lens, the 100-400L II. The all metal feel, aesthetic, and construction is top notch and the IQ is stellar. I...

Are you serious? You're correct about the ISO and I modified my previous posing but I replied to your cited posting, three posts later...

No we want cause market is not enought, but, not cause the lenses couldn't be less size and weight. The smaller the image circle the...
neuroanatomist replied to the thread A New Constant f/4 Aperture RF-S Zoom Coming.
Must? No, you can change the ISO. Like all triangles, the exposure triangle has three sides.
It's been a few months since I posted a...

None of that equivalencies are true.
APS-C F4 needs just the same exposure for the same image. Just the DOF change affirmation are...

To maintain the same DOF for same FOV with differently sized sensors and the same subject distance (update: and the same ISO), the 15-70...
neuroanatomist replied to the thread A New Constant f/4 Aperture RF-S Zoom Coming.
No, we won't. Not ever. Because physics. A 400/4 or 500/4 would be the same size and weight for an APS-C image circle as for a FF image...
