Here are a few helpful websites for Sony users and photographers in general.  Check 'em out; if you like the content or services provided, please make a donation.  My own guiding factors for making donations are; did the site help me save money or make up my mind in a purchase?  Do I return to the site regularly, say a few times a month, to browse any new material, even if it doesn't help me in a particular situation.   A gift of $5 or $10 helps the site owners keep up with fees such as hosting, domain, certificates, bandwidth, security and software updates to name a few, that, of course, doesn't include time or product costs etc.  The listing below is not in order of importance, I'm just adding the links as I visit them.  More will follow in the coming months.       Kenrockwell.com  Heavy on Nikon, but there's so much more.  Would you like to be able to determine the amount of energy produced by "mirror whip" on a particular DSLR?  Or how about the possibilities of regenerative joystick and control dial charging of the battery?  It's all here.  For people that may not need this kind of information, check out the vast collection of great articles (of which I've learned a lot) about general photography, especially his magnum opus, "your camera doesn't matter."  The site is huge, and a bit haphazardly arranged, so use the search bar for quickest results.   MHohner.de   A wealth of information on Sony/Minolta AF lenses, flash units, accessories and cameras.  Basically a complete specs/compatibility chart for all AF Minolta and Sony lenses and cameras.  Also see the FAQ page, which is very interesting.  Try to send this guy some money.  I see no link for CC or Paypal.    B&H Photo  Totally legit outfit.  Mostly the best prices.  Good return policy.  I've used them for years and never had a deal go bad.  The link is for Sony, Minolta and after-market lenses.   Adorama  Another good store with excellent prices, but for some reason lately, every time I try to order something, they're out of stock.   Good return policy.  Link is to all camera stuff.    1x.com  Great photos submitted by anyone, but editors approve photos before posting, which results in almost zero junk.     Cambridgeincolour.com  Site has beautiful pictures, and plenty of tutorials.  This guy is patient, and knows what he's doing.  Link goes directly to tutorials.   Sonyalpharumors.com   A big rumor driven site, but the author keeps up on all the latest happenings of the Sony DSLR/mirrorless/SLT dept, and is (ironically) probably the best and most accurate site for upcoming Sony announcements etc.  Updated about every day.   Strobist.blogspot.com  This site is a must for people wanting to learn off-camera flash use, (important for Real Estate photography) and includes equipment reviews and tips.   Butkus.org  or Orphancameras.com  Free info!  Site for getting old photography equipment user's manuals, including cameras, flashes, old photo catalogs etc.  Say you want an original manual for your old maxxum camera with a maxxum 4000 flash, this guy has both ready for download, and for free!  Please sent the guy a few bucks if you get something useful, that helps him help us all.   .  .
