A study in IBIS/OIS/stabilization​.
Evidently Fred Miranda is having trouble with the image stabilization in the new FE100-400.
So today I came up with a scheme.
I had the FEGM100400 on the a9, sat waiting for something to land, took some shots with IS enabled on
the lens.....evidently when you switch off the lens stabilization the IBIS on the a9 will also shut down.
Now here's where I got tricky.
I put the a9 into crop mode and put on an 1.4TC. So an effective 840mm.
No problem staying on the perched bird with lens stabilization on, but when I turned it off suddenly I felt the weaving
wobbling me trying to keep centered.
Flipped the lens IS back on and instantly the bird stabilizes in the EVF.
Bottom line my IS is working fine for now.

But it was also another study.
Cropability is necessary for birds/wildlife always needing to get closer.
My experience with Canon was more keepers with the 7Dii than the 1DXii because of the pixel density.
But what about the a9.
Theory says more cropability of the a9 over the 1DXII, 20.1mpx versus the a9's 24mpx.
So here is an image shot while the a9 was in crop mode with 1.4TC and 100-400GM=10mpx to work with. I can tell I had
14mpx less to work with and yes cropping in post for me, but was a good test of stabilization and what 10mpx can do in this
era of mega-mpx camers.

A7S and a5100 are the only ones that do a 'live composite' if I remember correctly.
I know Poof wore out fireworks July 4 with the Oly's. Yep would be nice.

I remembered posting up a Milky Way via the FE12-24 but this one was forgotten (I think), my first MW attempt with the
B18 (before receiving Sharpstar).....and speaking of Sharpstar, did anyone here purchase the Pure Light filter from Ian ??

Might soften the blow if she found out about the B18 :lol:

Just had a wicked moon halo over my house tonight.

Looks like a dirty lens, but its cloud.

Excellent image! The B18 is a perfect astro lens.

To answer your question, yes, I bought the Pure Night Filter. Do I think its worth it...not sure yet. I finally put it to use in the Smokies two weeks ago. These are two images, taken back to back, the first one without the Pure Night, the second one with. The only edit in post was to bring them both up by +1EV. Like I said, I am not sold...for the price I paid for it...I was expecting something better, and I don't typically shoot MW in areas where I need to eliminate the color cast...additionally, using it meant that there was one more piece of glass to keep clean and free of condensation...

I decided to reshoot the bottle of Grey Goose when I realized how much detail I lost by having the bottle backlit.

How about an HSL adj layer to suppress/reduce the yellow reflection artifacts in the glass? My idea is to not allow any color reflections that aren't otherwise seen in the frame.

This is just a small thought though; it's really nice as presented. :)

Very cool! I think a set of 3 small prints would look great on a wall.

Interesting, thanks David. I have both the glass and bottle on their own layers so I can adjust them separately. I did desaturate the cyans in the glass but I thought I should leave some color rather than just desaturate all color. I'll reduce but not completely lower the saturation and see how that looks.
