Viltrox 20mm f/2.8 Severe Field Curvature & Barrel Distortion?! Quick Lens Review & Test Charts
Переглядів 18214 днів тому
A short review of the Viltrox 20mm f/2.8 lens! Covering barrel distortion, vignetting, and sharing test charts to help you decide if it’s worth the price. Minor mistake: I was referring to field curvature on the test charts not barrel distortion, but it’s still visible. I got the lens at a discount for only at 100$, it's still pretty worth it.

Straight to the point
What you speak of is field curvature
you are right, looks like I made a mistake. Thank you for pointing that out. Well to be fair, this lens has both barrel distortion and field curvature.
Can I use any silicone based grease , or does it have to be specifically for lenses ?
for older lenses like these, you can use what you have in hand. the grease I used is for automotives
I found one of these locally for $10 for my Nikon film bodies and my Nikon D3. Really like the lens
That sounds great, The only frustrating thing about mine was the aperture and autofocus not working.
@@Protograph sorry to hear that and like the video
