Sigma BF (Beautiful Foolishness).

I think for most (all?) of them they really just changed the name and dropped the DG DN label. Other than the new silver color option. MPB usually has a nice selection of used L mount glass.
 
I too thought I would wait a while for the redesigned… typeface… of the i-series, since I have both M-mount and K-mount lenses that I can adapt. And they do work very nicely, though the rangefinder lenses are much more sensible on an adapter than the SLR lenses. Being able to set up shading compensation so easily is a very nice touch – I only did it with the lenses at f/5.6, but I could have created a second profile for wide open aperture if I wanted to. It's so easy to switch profiles, so why not?

But… yeah. Manual focus works well, but AF fits the gestalt of the camera so perfectly. And solves some problems.

The screen is a weak spot, so seeing to manually focus under adverse conditions is a challenge. Autofocus definitely eases the workload there, where manual focus needs one hand on the lens, one hand on the shutter, and a third to touch the screen for magnification. (It took me a while to figure out how to make the magnification 'hold' instead of timing out after two seconds.) Having autofocus cuts the number of hands needed in half.

I bought a used 45/2.8DGDN instead of waiting for the just-plain-DG version. (Its focal length fills the critical gap in my 35-40-50mm M-mount primes.) The different font doesn't bother me much (I'm absolutely someone who can spot the difference between Helvetica and Arial) and the advantage is that the typeface for the older lens makes the aperture values more prominent. If that sounds like rationalization it's only because it is – but it worked for me.

I don't know if the BF has it but on the fp L you can turn on magnification and the center portion is always magnified except with a half press of the shutter button. That bugged me at first but the logic of that with an adapted lens actually makes a lot of sense.You can always see the edges of the framing with the middle being zoomed in. Focus, then half press, final compose and shoot. Once you let go of the shutter release the center is zoomed again. Saves a button press every time you want to focus and is quicker once you get used to that logic.
 
Success, maybe. Focus Camera had the new 45/2.8 showing in stock so I pounced. Let’s see if it’s actually available.

I’ve been checking the linked retailers from the Sigma site a few times per day. I have a 24/3.5 on order locally (paid with a trade in Z mount lens) and am still looking for a 17/4.

Interesting. I looked, but couldn't see any setting for that, and there aren't a lot of places for settings to hide on this camera. But that got me looking at other possibilities, and sure enough, clicking the centre of the wheel while the shutter button is half-pressed will magnify the screen. So that's easier, if the centre is what I want magnified, and it usually is.

Well done! I'm hoping that the status is correct and it will be on its way to you shortly.

Great find!
 
The centre button is handy. Normally it brings up the options, but with the shutter half-depressed it changes the AF selection zone from area to 1-point. So in AF-C it selects a new subject to track, and in AF-S it recalculates the focus and relocks the exposure.

Another control quirk I've noticed is that the playback button only shows blinking highlight warnings with a full press, not a touch. I don't mind – I use two levels of zebra warnings when recording photos – but it's good to know that they display information differently.

The ellipsis … button shows the battery percentage, clock time, and shots remaining when touched instead of pressed.

And one of my favourite things is being able to lightly tap the power button (not haptic) to sleep the camera, quickly woken with the shutter button, so that I can conserve power but still leave the sleep timer set to something generous.

It doesn't have a lot of controls, but it makes good use of them.

The 45? I wanted the newest version because the person at Sigma USA I spoke with implied that there might be minor product improvements over the original.

The only other change to the 45mm (beyond the font) was that it now works with the magnetic lens cap, which made it slightly heavier.

Optically Sigma didn't change anything. (Sigma confirmed this)
 
I picked up a TTArtisans 75/2for the BF, but it’s going back - in testing I found the aperture never opens up beyond f/4 in program or shutter priority mode and there are no firmware updates shown on the manufacturer’s website. I’m not willing to take the risk, and it points up the issues with third party lenses. I’m pretty sure TTArtisan isn’t part of the L Mount Alliance so they must be reverse engineering.
