speeds available in "T" mode

I'm interested in the Q2's potential for night time starscape photography.  What are the shutter speed limits at different ISO values in "T" mode?  Anyone?

Thanks,

Brent

I think you'd find it helpful to read this thread where there is quite an extensive discussion about the possible use of the Q2 for astro photography (warning: it's not going to encourage you). The manual makes it clear that in T mode the maximum shuuter speed you'll get is 120 seconds.

Thanks Stephen,

I had read that thread, but it is inconclusive for the question I am asking. Hence my wish to clarify.  120 seconds is more than enough if it can be used with higher ISO values in “T” mode.  But if the ISO/shutter limits are the same in “T” mode as per normal (eg., 4 seconds at ISO 3200), why even have a time mode?

So I’m still asking: can one get 120 seconds (or 15 or 30) with ISO 3200?

It is impossible to remove noise reduction

Well, alright then!😉. I guess no one knows the answer offhand.  But if anyone who owns the Q2 wants to experiment to find out the answer at some point, I'd still appreciate it.

Thanks

Also, Massimo.  Normally you should start a new thread to ask a new question.  Otherwise your querry will remain buried in a thread that is not about your question, and fewer will find it. FWIW: I do not own the Q2, but if you're referring to the noise reduction routine the camera performs on long exposures, the instruction manual leads me to believe that it cannot be turned off or cancelled.

Try it yourself and let us know. If you are shopping and are determined to do astro-photography then you might want to look at a different brand.

The short answer is that, unfortunately, T mode does not help extend the exposure duration at various ISOs. Tested and demonstrated here:

If I could try it, Pico, I would, and I would happily share what I learned.  But since I don't live anywhere near a Q2, I need to ask on line.  As for brand issues, I can and have used other Leica cameras for the type of landscape-astrophotography in which I'm interested.  I just was trying to determine whether I could use the Q2 for the same.  And 'not really shopping, but wondering if one day the Q2 could replace multiple cameras now in my possession.  And, judging from Jay's post, the answer is a big, marginal "maybe."

Jay (I assume?),

Thank you heartily for your concise post that tells me exactly what I needed to know, and for the very informative video.  My searches had not turned that one up.
