My recommendation is don't skimp out on rain gear. When you are out in the elements with thousands of dollars worth of equipment a couple hundred dollars for good quality rain gear is well worth the investment. I agree in general (...)
While I really dig quality, I have, in general, to disagree here. I recommend a two-step strategy: first, buy a cheap solution, once that isn't sufficient, upgrade to professional grade equipment. I have a lot of cheap S___ that I never needed or even wanted to need more than once
If OP goes out into a downpour on a daily basis, sure, he should invest a few hundred bob on something that fits his workflow. But I haven't heard him about requirements that warrant more than a plastic bag with a few strategically placed holes. Spending lots of money on stuff you don't use, just
because you have a pricey camera, is not very bright, in my book.
I live in a country where it rains eight months out of twelve and I don't need anything more expensive than an Op/tech bag... just saying YMMV.
