A common theme on many of these forums involves folks who argue over the sharpness of a particular lens. The argument often ends with "You got a bad sample. Send it back." Honestly, there seem to be an awful lot of "bad samples" floating around out there. Is the lens manufacturing process really so loose that a high number of bad samples would be produced? Are bad samples just an aberration, or is there a range of sharpness (from great to poor) that affects all lenses? Do lens manufacturers test a lens before boxing it up, and is there some minimum level of performance that renders the lens "good enough?" Finally, how can one know if a newly-purchased lens is a bad sample, other than by making a totally subjective assessment by comparing results to results claimed by others?
I have neither the time, skill, or desire to run lab tests on every lens I buy, and if a lens doesn't meet my expectations, I have no problem sending it back. That said, I see no reason to settle for "bad copy" when a better copy can be had for the same price. Thoughts?

The Sony a7CR is a high-resolution addition to the company's compact full-frame a7C series. So what did we make of it and where does it leave the a7 IV that it sits just above?
Lomography's LomoChrome '92 is designed to mimic the look of classic drugstore film that used to fill family photo albums. As we discovered, to shoot with it is to embrace the unexpected, from strange color shifts to odd textures and oversized grain.
The LowePro PhotoSport Outdoor is a camera pack for photographers who also need a well-designed daypack for hiking and other outdoor use. If that sounds like you, the PhotoSport Outdoor may be a great choice, but as with any hybrid product, there are a few tradeoffs.
The Sony a7C II refreshes the compact full-frame with a 33MP sensor, the addition of a front control dial, a dedicated 'AI' processor, 10-bit 4K/60p video and more. It's a definite improvement, but it helps if you value its compact form.
Why is the Peak Design Everyday Backpack so widely used? A snazzy design? Exceptional utility? A combination of both? After testing one, it's clear why this bag deserves every accolade it's received.
