I'm getting my first pair of progressive glasses. I decided to go with Warby Parker rather than getting lenses from my local eye doctor because my doctor charged twice as much as Warby and I could not afford it. This is despite warnings from my doctor that progressive lenses must be measured in person. How will I know if the Warby Parker lenses aren't good enough? [more inside]

I have two pairs of old glasses I really like, and want new lenses for them. Is there anywhere in Boston that will give me a good deal on them? Single vision, weak prescription, polycarbonate. I could probably be interested in adding the first AR option. Costco is not an option. Walmart is $79, but takes several weeks. Where is the best place to have my new prescription filled?
I'm looking at buying a used Pentax K5 II as my main camera rig. The most important use of this camera will be for documenting fieldwork, including photographing specimens in the field.

Sigma 18-125mm f/3.8-5.6 AF DC OS HSM vs. Canon EF-S 15-85mm f/3.5-5.6 IS USM, besides the obvious zoom range differences is the Canon really worth twice the Sigma? I've checked a number of reviews and it doesn't look like the Canon's advantage is as clear cut as the price would suggest.

About ten years ago, I was given a couple Pentax 35mm film SLR bodies, and some lenses, which I was happy with. Especially the SMC-M 50mm f/1.4 lens, with which I discovered bokeh and existing-light photography. But after a while, I got tired of having to store and process film, since I just put all the pictures into my computer anyway. So I got a *ist DS, since that was compatible with all my lenses. But my favorite prime lens has been turned into a zoom by the reduced sensor size. The closest equivalent I've found is the FA 31mm Limited, but that costs ~$1000 USD, and its not even f1.4, its f1.8. Given this issue, along with the fussiness of getting all the auto-exposure/focus stuff to work the way I want it to, and I'm really missing my film camera bodies. Or is there an alternative?
