I did as you instructed and got photos! It still functions! Yea! I had been following settings in an article. F8. 1/500-1/1000 and ISO 100. Started today with your formula and worked down to these and got a series of photos. Need to work on fine-tuning by putting it on a tripod and adjusting 1 factor at a time to get best histogram, then work on focus. Lots to learn! If I get any decent eclipse shots, I’ll post and let you know. Thanks so much.
What youve quoted from the article is approx correct bright sunny day settings WITHOUT any filter. Some Hogsters call that "sunny 16" but avoid such jargon unless you really WANT to seem like a dimbulb ....
Worse yet, mention of "sunny 16" can trigger 3 pages of verbose BS from our resident geek wannabee about how its actually off by 5/16 of a stop :-(
Are you using an eclipse filter if not you can damage the sensor from the light of the sun.

Yes, thanks. I bought ND100000. 16.5 stops. After reading more, I felt misled and might have bought ND1000000 (6 zeroes, not 5). But no time to revise and 16.5 sounds like it will suffice.

That jargon was from before I took up this hobby! But this week i feel like a dimbulb! Maybe I should have stuck with macrame—oh wait, I missed that craft’s era too! Sure would have been less expensive, though!

Sometimes its helpful to read the opening post. Why not give it a shot ;-)

Anything can get expensive if you let it. Did you have beads in your macrame ? Theres a rather pricey bead shop here in town ....

16 stops is ND 4.8, and anything from 4.0 or beyond is safe for solar observing. Youve got an extra 3 stops beyond 4.0, just in case the sensor possibly needs even more protection than your eyes.
As to counting up all your zeros, you might find that the standard density notation is far more comprehensible than those ginormous lengthy numbers that you mentioned. (Its a little trick called an inverse log scale. It can take really unwieldy numbers and compact them into manageable bite-sized notation.)
In whole stops the scale goes 0.3, 0.6, 0.9, 1.2, 1.5, 1.8, and on and on. Each 0.3 that you add is one more stop. Its just plain dirt simple addition, over and over. (NEVER ask WHY the increment is always 0.3 and your head wont hurt !)

No patience for macrame..or knitting!

Right. Not asking. Head hurts just thinking about asking. Do not need to know! My idea of ‘math’ is phone numbers and the Dewey Decimal System and recipe measurements.

I put the Tamron 150-500mm tele on my Sony a6000 crop sensor. I can get photos in S, A, and Automatic modes...but nothing in Manual mode. What am I doing wrong? What settings do I need to change? This is to be my setup for shooting the Annular Solar Eclipse next week. I will need to set focus in advance. There are choices on the lens barrel---VC modes, VC on/off, and AF/MF. (I will use ND100000 filter then. And not look through viewfinder.) I searched 'net. Could not find any answers to this dilemma!
Thanks.

Update: everything worked just fine and I got some good results at Bisti Wilderness in NM for the annular solar eclipse Oct. 14. Here are screenshots of some. Not sure when I'll get around to editing but I'm grateful for all the UHH help and my "coach" Chuck Winter.

Thanks! I am excited! Learned so much.

Recipe math is no joke. Nonmetric kitchen measurements are as unweildy as the old UK currency of pounds, shillings, and pence. The kichen stuff seems actually worse !
OTOH, Dewey Decimal ... I have an MLS for that. I can sort DD from LC from IBSN, etc. Just one of my multitude of obsolete skills.
