Aren't these a little ... ah ... large for f/1.8 ?

While 'Art'-like, still no statement about improved QC (and yes, Tamron, you could also do some homework on this ...).

It was also about time that they improved their rather crappy finish honestly speaking.

The 45mm f1.8 indeed is pretty large.

 

But the 35mm f1,8 is not especially large, when you see that they went for recessing the front element a bit (which naturally makes it a bit longer and wider than the Canon 35mm f2 IS USM and Nikkor 35mm f1.8. It is not unusually or shockingly larger.
