Has anyone with both Q2 and Q3 tried using the new BP-SCL6 battery on the Q2?
If so, does it function normally at full capacity without a firmware update? Also, can the original Leica Q2 or Nitecore ULSL chargers properly charge the new BP-SCL6 battery?
Leica say September for compatibility with the Q2. July for the SL2/SL2s and December for the SL (601)
edit: that's for certifications. Looks like it's compatible already......

Good to know.
I just bought the new SCL6 batter for the Q2 and will use the Q2 charger.
Leica claims the SCL6 on the Q3 provides 350 shots per charge, which is the same as the Q2 + SCL4 although the latest battery provides 18% more juice. This implies that using the SCL6 battery on the Q2 may give you more shots per charge compared to the Q3.
350 + 18% more is equal to 413, so perhaps the Q2 + SCL4 provices 413 shots per charge... ??

I have the new Q3 battery to use in my SL2 camera. It has zero charge left out of the box ( first time I've seen that with a battery purchase) Or maybe it doesn't charge my SL2. Need to check that out with the SL2 charger regardless.
My idea is to test this new, stronger battery ( I think I read 18-20% stronger?) on my SL2 to see if:
1. It helps eliminate the camera block for using high speed continuous or 4K settings when the current battery drops below 20% charge.
2. Or, maybe just gives me another 18-20% usage/time over the current SL battery before the camera blocks access to high speed continuous or shooting 4K mode settings when the battery drops below 20% charge.
I'm not exactly sure how best to test #2, if some of you have some advice/ideas 🙏🏼

The Q3 battery charged to 100% with the SL2 charger no problem as @lifeandmylens informed earlier in the thread ✅ Now to do some comparison scenarios to see what I can come up with operationally.

Upon my first test, it seems the SL2 camera will still present "Battery Power not sufficient for 4K recoding and Continuous Shooting" even with the more powerful Q3 battery, when the Q3 battery falls to about 20% charge😢 at least with the current SL2 firmware v 5.1. *From what I read, Leica is still in the process of certifying the Q3 battery for use in the SL2 camera. Results due this month(July)
Also since the Q3 is about 18% stronger than the original SL2 battery maybe one way to look at it is the Q3 battery may provide up to about 18% more shooting time before it blocks 4K recording/Continuous Shooting at 20% or below battery charge.
Pretty easy to work with if this doesn't catch you off guard otherwise. But still...

I wonder if the Q series had a custom 35mm Summilux f1.7 with all the macro functions would it be smaller or bigger than the 28mm Summilux (or really it's more like a 26mm). Just got the Q2 today. It's much wider than the good old RX1Rii, but it doesn't separate subjects as well as the 35/f2 Sonnar for things like environmental portraits.

If the "uncorrected" Q2 image is used without applying any distortion correction and just cropped to match the field of view of the "corrected" DNG, we find that the uncorrected version measures approximately 25.2mm.
Consequently, the Leica 28/1.7 Lux lens exhibits the following field of view:
Essentially, this lens behaves like a 25/1.7 lens with significant distortion. Leica addressed this distortion by implementing correction and making a slight crop, resulting in a field of view of 26.7mm. However, in terms of signal-to-noise ratio (SNR), it is like to using a lens with an aperture size of f/1.8 (26.7mm f/1.8).
By comparing the two values:
26.7 / 25.2 = 1.06
f/1.7 x 1.06 = f/1.8
Approximating the numbers we get what we already knew: 25mm uncorrected, 27mm corrected out of the camera.

So many people here over the years have been swearing it was a 25.Xmm FOV even when corrected
Due to the distortion correction crop, can we also say the Q cameras' effective imaging area off the sensor is a bit smaller than full frame?
Indeed, with its focal length of approximately 27mm, it seems reasonable for Leica to refer to this lens as a 28mm lens. Although it is possible to eliminate the correction and capture a wider image, I don't anticipate doing this frequently.
I did a comparison of the amount of blur produced when shooting with both lenses set at f/1.7. (The Q lens at its maximum aperture)
To my eyes, the blur appears to be very similar. This is to be expected since I made an effort to align the framing as precisely as I could by adjusting my distance. Still the Q2 will always show more elements in the background towards the corners.

I shoot all my cameras in manual exposure mode. Do I understand it right that in Leica Q3 I cannot assign thumbwheel to change shutter speed in 1/3 steps in the whole shutter speed range? The only option is to set closest speed on a dial, and adjust to +-1/3 or +-2/3 with thumbwheel?

I don’t think you assign shutter speed to the rear dial. But setting manual ISO, manual aperture, auto shutter — then using that dial for exposure comp accomplishes something very close to manual with 1/3 stop increments of shutter speed change.

I imagine it is the same with M series. Whew, this saves me a dollar or thousands!

On M’s and , I think Q’s (mine is on loan so I can’t compare), you set shutter speed in half stops on the dial. Lenses are also set in half stops. ISO is in full stops on the mechanical dial or in between if assigned to a custom button.
YOu can not re-assign shutter or aperture functions on an M.

This is quite close to the 28mm focal length of the Leica 28/1.4 Lux, assuming that the latter is indeed a 28mm lens when focused at infinity.
Are all these calculations based on the 28 Lux being precisely 28mm? My understanding is that lenses actual focal length never correspond to the marketing number but are rounded off, sometimes quite generously. From memory even the standard 50mm was never 50mm but 51.2mm (or some such number) based on early Leica 50mm lenses.

Indeed, you bring up a good point. The Leica 28mm f/1.4 Summilux lens is reported to have an exact diagonal angle of view of 75 degrees according to Leica. Based on the calculations, the focal length derived from a 75-degree diagonal angle of view is approximately 28.28mm, which is slightly different from the commonly referred to 28mm.
In the case of my Voigtlander 28mm f/2 Ultron II lens, with a slightly narrower diagonal angle of view of 74.51 degrees, the calculated focal length comes out to be approximately 28.50mm. It's worth noting that there can be some optical variation from one lens copy to another, which may affect the actual angle of view and focal length.
Considering these calculations, it appears that the lens on the Leica Q2 is not too far off from the 28mm focal length, confirming its "wider-than-28mm" nature as widely known. I decided to personally test it out and wanted to share my findings.
By incorporating the additional "0.28mm" focal length into my previous calculations, we arrive at the 28mm f/1.7 Lux lens measuring 25.5mm without correction and precisely 27mm after built-in correction.
