Can one select a relative value (1/FL) as the shutter speed limit on SL2-S?

Have recently traded in my SL for an SL2-S and am not seeing the ability to limit the longest shutter speed under Auto ISO to a relative value (1/FL, 1/2FL. etc.). Seems I had this with the SL601 and it is enabled also on the Q2M (even though it is a fixed lens camera). The camera is operating with firmware version 2.1. IBIS seems very effective, but I would like a relative value as I plan to use a wide range of focal lengths on this camera. 

Thanks in advance and apologies if this has been a subject before - looked but couldn't find an answer.

From I can see from my SL2 menu, and the manual, you can set limits on SETTINGS AUTO ISO for Maximum ISO and shutter times of AUTO, 1/2000, and longer. There does not appear to be a way to set shutter time according to FL. At the moment, I only use M lenses, so have no idea if the same holds true when an SL lens is mounted.

Thanks for your reply. I also use mostly M-mount lenses with my SL cameras, though I sometimes mount Sigma L-mount alliance autofocus lenses and have not noticed a change in the option with these lenses. Will check again. 

Perhaps I am the only one missing this setting. ;^)

Alan;

On the M series digital cameras, most just set the shutter speed to 1/f, 2/f, 3/f, etc. While this setting is available for the SL2/SL2-S, I do not recommend it, and here's why.

When I got my SL2-S, I went out to the town square at night to photograph the lights last year over the holidays. I set my camera at Aperture Priority, Auto ISO, ISO 12,800 (max)  and at 2/f, just to be safe. When the camera is set this way, it prioritizes the 2x the focal length of the lens over the Max ISO, so pretty much for every shot, I was shooting at 1/125sec or in some cases 1/250sec and the ISO was pegged at 12,800, neither of which which were optimal for my use-case. I would have much rather shot at 1/30 or 1/60 sec at ISO 3200 or something like that. Luckily, the SL2-S is pretty great at ISO 12,800, so all was ok.

In the Auto ISO setting area of the menu, there is a selection called Max or Maximum Shutter Speed. It is really counter-intuitive, because what they really mean is Minimum Shutter Speed. I typically set mine at 1/30 or 1/60 sec. This way, the ISO won't necessarily peg at 12,800 or whatever your max ISO setting is. During daylight, I either set my Auto ISO to 400 or just dial it in at 100 ISO, but when on Auto ISO, my Max Shutter Speed remains unchanged.

Another tip is for street photography, sometimes good 'ol manual control (you set the Shutter Speed and Aperture) or just set the camera to Shutter Priority. Many complain that their photos aren't sharp, when in actuality, they need a faster Shutter Speed, and no, IBIS won't help with stopping action (;-)

Make sense?

Brad,

With my SL2-s I notice that with Auto Iso and Shutter Speed Limit at <auto>, it does indeed use 1/2F as minimum shutter speed.

However I can not find a menu item where I can change this 1/2F into say 1/F or so, apart from setting a shutter speed limit other than <auto>

Hope this makes sense....

Cheers, Arnold

The term shutter speed has always annoyed me. The shutter speed is always the same, whether it is how fast the leaves of a leaf shutter open and close, or how fast the curtains of a focal plane shutter travel, and so on. We are setting the exposure time, not the speed of the shutter. So, yes, your camera may b able to set a minimum exposure time of, say, 1/4000 of a second, and a maximum exposure time of, say, 60 seconds.

Thank you for these replies and helpful suggestions. I will have a closer look at the menu settings and camera response this weekend.

You should set the Auto ISO limit to a value, for example 6400 or 12,800 ISO. I do not believe that the SL2 or SL2-S has the option to set 1/f, 2/f etc. this is done with setting the ISO option and the Max Settings as described previously

Concur. It seems perhaps that the camera is considering the lens focal length into shutter speed setting when the shutter limit is set to “auto” rather than a set value. Setting 1/fl or 1/2fl does not seem possible  in this FW version. Auto ISO + auto shutter gives a little too much control to the camera for my shooting taste. Thanks for the insight.
