Beleive it or not, id say all of my lenses were cheap when it comes to price, but i love them all
sigma dg macro f4-5.6 70-300mm is a great zoom lens for the price and i have gotten magnificant bokeh with it, best outdoor lens ive had yet
theres a sample.
i also have one of those "paper weight" takumars, but they are great if you know how to use them, they make really great portrait lenses
not bad for a paperweight to say the least this is stopped down to f2.5
hten theres the 50mm smc f1.7 but i dont guess thats considered a "junk" lens, but i got it for quite the bargain.
i believe this was either at 1.7
