Dust inside brand new lens, Canon quality problem?

[stillviking]

Hello people,

Just bought 2 brand new Canon RF 16mm 2.8 (returned 1st one because same problem), both say Made in Taiwan and had dust inside lens.

Is this a control quality problem? Dust inside brand new lens I think it's a factory problem? Happened to anyone?

First time it happens to me.

I used the RF16. I do not notice dust. Not in the lens nor the photos.

I've never had that problem, even with refurbished lenses. What if it's the same lens!?
For what it's worth, I doubt there is enough dust in there to affect your photos.
Take a look at what Roger Cicala wrote about a fly!

I've been doing lens stuff for a long time now. Long time. Trust me; it's hard to remain polite the 843,911th time some newbie goes into hysterics because there's dust in their lens. Telling them it doesn't matter a bit, and that all their other lenses have dust they just can't see ( because...

Hello! Thanks for feedback, looks I need to return and try to buy a 3d copy! Unfortunately it's not the same lens.

Good luck!

I just tried my 2nd RF 16mm copy (while not return) and it was pretty ok for indoors and closeups (focus not far) but for landscape (focus in infinity) it looked real horrible to be honest only center was sharp but close to center it was already without detail and corners very mushy. Same experience? This makes me think this is a vlog lens created for close focus objects and not for landscape.

I've never tried focusing it to infinity. Where I live, there's a lot of trees. The few places where I have a chance to focus that far away, are not super interesting for me, but I will try tomorrow. I'll take EF 14mm f/2.8 for comparison. I do think the 16 is better at the sides closer though...

Mine is described by this review, tack sharp in the centre and near centre. You may have bad copy. https://www.opticallimits.com/canon_eos_ff/1136-canonrf16f28?start=1

Mine can only be said to slightly soft when viewed at 100% beyond halfway to the sides. !

So, I agree with Alan

Things happen during production. When twelve years ago I bought a new ef 70-200mm f/2.8L IS, I was shocked and appalled to see quite a bit of dust inside, when looking through the front element. Replacement was fine.

Of course it depends on the use of this lens. It cannot be compared to a top L lens. But you can certainly take beautiful photos with it. Here is an astro photo also set to infinity.
