I would guess that it is a combination of Vista + Lens. The Chinese like having syllables from western words in their naming.

Looks like Vistilen it's the brand they would use to sell Nikon Z Mount and Canon RF lenses with licensed autofocus capabilities.

I just remembered I posted a careful comparison of the RF 200-800mm and RF 100-500mm close up shots. The upshot was that at ~3.5m (or...

That's the SLR era lens. It was excellent but is huge, heavy, and the AF is very slow by today's standards.
But yes, that lens is one...

To reiterate: If you want less noise at high ISO (i.e., better actual image quality), you need a bigger sensor to collect more light...

I understand the point about shot noise dominating at higher ISOs and that total light collection is a primary driver of overall...

That depends on how the camera handles ISO 1000. If it's like most Canon DSLRs handled ISO 1000, it's actually using ISO 800 analog...
