Many thanks for the answers. Is Q10 faster, more responsive, compared to the first Q?

...is there any difference in IQ between first Q and Q10? I'm asking more on RAW-quality, JPG quality is less relevant. I'm mostly interested in DR and noise.

One can see craters Kepler, Copernicus and Erastothenes up (left to right) and Gassendi plus Mare Humorum dark area left down.

The moon with genuine (1st) Q and small 500 mm telescope (4 images stacked, 500/4.4, ISO 125 1/125 s. not cropped). The seeing was so-so at best. I'm quite happy with the result, but have to check if good 300 mm lens could be more useful for most moon photos.

I used "sun foil" for visual observation (special Baader sun foil) glued to some step down ring as a filter, This was my first time with Q and the sun, but it seems that ISO around 160, 1/800 s and f11 should be OK.

Tokina RMC 400/5.6 - how to open?
Posted By Piotrek K

Thank you, this is extremely useful! I checked before, there are no additional screws under the focusing rubber unfortunately. No problem if it would focus past ininity, in this case I would just mark proper place with some paint, like in case of some my zooms. But it is focusing at circa 50 meters when at infinity mark...

It seems to be a nice lens: quite small, relatively light, with good rotating tripod collar, not bad at f 8/f11...

Tokina RMC 400/5.6 - how to open?
Posted By Piotrek K

I have a nice Tokina 400/5.6 which I need to open to adjust the infinity focus. I suppose this is possible as it was definitely made in many mounts, But I do not see the possibility:

- it has one screw on the lens barrel, but when I unsrew it I can't move anything,
- I do not see how to open it from the front - the nameplate is not perpendicular to the lens barrel, it is almost perpendicular to the front glass element; i do not see how to use lens spanner here...

Maybe someone tried to do this already and could offer any insight?



This is the lens, btw:
