So i need a wide lens the only ones for my r10 is the rf 10-20L which is out of my budget and then we got the rfs and the efs version and i decieded to buy the ef version for dirt cheap and its sealed and buying from sm1 ik so ik its not been used ever so is the lens good and except for the variable aperture is there anything that may be problematic for that lens?

UPDATE: i got the efs lens and its really good and i like it and its not as heavy as i thought and i got some decent images with it and its focus is sharp with no noticable noise i like the lens and its really really good apart from distortion i see while 100% zoomed in on corners its not noticxable at all when not pixel peeping its a really good lens way better than i thoguht it would be

So i recently got an eos r10 with its 18-150 kit lens and i am getting noise in every photos so far even in 100 iso in broad daylight at f/3.5 i am still getting noisy photos what does it mean, is my camera a defaulted piece or sm i bought it brand new btw so what to do now any suggestions?

sorry i didnt attach an example so here they are andf yes i am pixel peeping but i want to crop in and that is why i am pixel peeping and its not visible at full screen but once i crop it or such then the noise is visible and for comarisn i included photo from my r50 and r10 and you can see r50 on 400 iso has less or similar noise as r10 on 100 iso
