Hey that's a good image of Orion can you not change the aperture if you go manual
Focus looks ok what does it look like at full size
Well, after reading the manual (you know, that thing us guys tend to ignore?), I found out how to change the aperture while in manual mode. However,
with this lens, I can only take the F stop down to 5.6 at 55mm and down to 3.5 while at 18mm. It will not go any lower than that.
If you could see the full sized 4272 x 2848 frame, you'd see that they stars are actually out of focus slightly.
However, I discovered (also by reading the manual....dang I wish they'd tell us to read these things!) that I can go to "Live View" and using the
LCD display, I can move the focus square around the frame to where I want, then hit the magnify button. It has 2 levels, 5x an 10x, which allows me to
very, very, very gently adjust the focus even more.
So I'll be playing with that tonight and see how that works out. However, for today I'm going to work on this home made adapter ring so I can try
attaching my FD 70mm - 210mm telephoto lens and see how well it performs (i'm a bit worried about the difference in the 44mm to 42mm focusing
difference when Canon changed it back in the late 80's)
