Here a quick example with Sigma 120-400 HSM OS - Tripod, + remote @3s - Traget is about 80-100meters

First with 02lens @15 : target is the red circle

Now with the 120-400 Wide open

Crop @ 50%

A few frames using the 560mm scope and the Q.
This should give me about 70x magnification.
All full frame at about a distance 60-70 feet. Remember these birds are barely larger than a man's thumb.
Big disadvantage of the Q for this kind of shooting is the slow buffer for RAW files. It's just too damn slow for fast moving birds forcing me to use JPG.
Then I have to give up the advantages of RAW processing which is a big deal with such a tiny sensor and using high ISO.

I'm not sure why you're concerned about RAW ... these look really good to me. You really nailed the focus, and that lens combination is obviously very sharp.

I agree with reh321, those are great shots of much more colourful birds than there are in my part of the world. Your setup looks great too. I have been wondering about a scope for some time, I'm mainly after sea birds and they stay out on the mud flats well out of range of my equipment. I know very little about scopes but I always thought their optics were very simple compared to those in lenses and consequently would not produce as good images, but your images are very good.

Smoother tonal range , sharpens better, more accurate WB etc. See pic

What I use is a 3 element APO triplet. It cost about $1300 now.
It's because they are so simple that they have resolution to burn. See the blowup shots
Full frame and crop (NOTE: Not taken through a Q but a K20 sensor).

Beautiful images wildman, they are sharp. To lessen the Q Raw buffer problem I bracket. Set Q to Raw, set to autobracket. Set brackets for -.3, 0, +.3. Q will shoot faster than normal. No idea why.
thanks

Absolutely beautiful, excellent detail, very well done, thank you for the information.

Pretty much stuck at home this weekend so a few more of the usual backyard suspects. But I did capture my favorite Spring Bird - the White-Throated Sparrow the last one in the series.
But I could use the practice. For this kind of shooting the Q is not Ideal. Not nearly as fast and responsive as the K5.
It's a strange piece of work - the more I use it the more confused I get about who or what is was designed for.
Oh well will soldier on.

Some backyard, at most I get a couple of crows and and the odd stray pigeon in mine, really great shots again.

Superb pictures which are now missing
Same problem with the Q : too slow with raw, I use jpeg only
Q7 : jpeg + raw is ok
What is your scope model ? I still remember the picture, it seems to be much longer than mine ?

Yes, it was a very good tip you gave earlier, bot only jpeg with the Q, raw is too slooow, and jpeg+raw with Q7

Astro Tech APO 80mm triplet FPL-53. 560mm f/7.1.
Not available anymore. I think it's been replaced with this -
