The Sigma 70-210APO works well in manual focus. I get some nice sharp shots. It just isn't great for action shots.
Yes I bought the Sigma 70-300APO a few years ago and did some test shots with it. I haven't used it much lately. Maybe i'll hunt it out and test it again. I'm always looking for birding lenses to try. I lost about a year and a half of photos the other month when a hard drive quit. I think the test shots were among those lost.
I had a few people want my Mamyia's but my daughter told me she wants all my photography equipment when I fade away. I'll save them for her. I'm not sure why she is a die hard Nikon person.

Hard Drives - the old kind ... were doomed to failure, at some point along the way. These new ones, though - will last a whole lot longer. Also, SSDs are getting a lot of folks out of trouble ... very unlikely those things will EVER fail! ... Plus, you can use them for automatic back-up of all important stuff, if you don't already use an external drive, in unison - a good idea!!! ... But, also - I don't wipe off my SD cards, after downloading. I download using the USB cable. And, when the card's full, after the last transfer, they are retired, labeled, and stored in a case. This way, if I ever lose anything, I can refer back to the original save, on the card. SD cards are so inexpensive, now ... it's a good idea to buy several, at a time, and just pop in a new one. Also, there's absolutely NO substitute for good maintenance, and a good AVU - to protect yourself against malicious downloads, and other hacking attacks.
There are many AVUs out there - some paid, some free. MS also has Defender and MS Security Essentials, both, either, integrated into the OS, or free for the asking. If you don't use one or the other, already ... and don't have a paid service - activate it in your Windows OS. It won't do maintenance - that part's up to you ... but there are many free utilities on the Net, which will check your registry, and do HD Defragmentation - two items, which should be checked as often as you think of them - hopefully - daily, or, at the very least - weekly. Once your Registry gets out of whack, you could get yourself into REAL trouble. Defragmentation - speeds up your HD access, and keeps things you use more often - closer to the laser's most readily-accessed pick-up point. Not doing a Defrag every once in a while, will slow down your computer, and depending on the state of neglect - could make you more vulnerable. You can also clear your browser rather simply - just look at Settings. Also, there's a built-in utility, in Windows, for wiping clean all the accumulated junk. Use it often. Don't pay any attention to the warnings - you don't even NEED that stuff - no idea why they warn you! ... For Registry tuning - get a freebie from the Net. System Mechanic's a good one. They will clean junk, speed up the HD, and check the Registry for free. If you want full service, the monthly isn't that much. But, if you use Defender ... you don't need anything more, really - it does a pretty good job ... but keep working it ... download updates!
