>>3518164> Great lenses for APS-C are expensive lenses.APS-C doesn't have too many particularly expensive lenses, most are $500 and under, only a few are $1k+.
> FF lenses of equivalent quality costs less.Sure. Particularly at some point above $500 or so the FF lenses feel like increasingly better value-performance than the APS-C lenses. But below that you've now got offers like pic related.
Plus you're not forbidden from using the FF lenses that have good center sharpness on APS-C. Often this is what makes FF lenses - particularly zooms a bit cheaper, too.
> The glass needs to be extraordinary precise to get same results = Drives up the cost.FF glass needed more work too because it is bigger plus they expect that you've got more money, which also drives up the cost.
Not many lenses are better than an average "nifty fifty" and cost <$500.
