Pentax SMC-DA 15mm F4 ED AL Limted

Pentax smc DA 15mm f/4 ED AL Limited review

Compact and lightweight; High quality aluminium construction; Quick shift manual focus system; Built-in sliding hood (but see below); Good flare resistance; Almost no distortion; Small 49mm thread, doesn't require slim filters; Rather soft at F4 - F5.6; Hood design causes problems with filter use (particularly square systems);
