The venerable little pancake lens, shorter than it is wide, packable, turn your mirrorless to the equivilent size of a point and shoot and make your camera better than your phone.
I put a post up a while back about if you could only carry three lenses, and most of the replies included a pancake lens...if the definition above works.
The conversation was interesting to see how people view only having a limited choice of three lenses, usually there is a lot of compromise in some area of your shooting. The conversation was directed more for people getting into photography for the first time and as some sort of direction what lenses more seasoned shooters would choose.
The flip side to that conversation was directed again at a newer photographer (purposely without pointing that out) that if the dSLR was too big and the phone camera wouldn't cut it what point and shoot camera would you choose?
Well it appears the point and shoot isn't greatly loved by many, the phone is a better option for a quick snap, and @Munch made the group aware of a great app he has been using for years on his cell phone with great success.
A lot of responders felt a mirrorless with a prime pancake lens would give much better image for a similar size and in some cases for less money.
So...pancake lenses, primes or mini zooms, what's your take, love them hate them. For me in the Sony line up the only lens that can be considered a pancake zoom is the 16-50 kit lens and like most it ends up as a paperweight or being sold off.
@Pathfinder had some great things to say about pancakes and small primes in general, hopefully he'll jump in here and tell us his favorites
In my bag I have a 20/2.8 sadly I don't have mine with me right now but it's this one. I 'made' myself take just that lens and a a6300 on a two week ride and expected to be having a sense of loss at some point or another but kept telling myself my legs were my zoom.
I knew that the majority of the week would be more landscape based shots and the little 20mm didn't disappoint for what I needed it for.
With this particular lens even though it'll open up to 2.8, it is at its best at 5.6, just giving a very mild bokeh but remarkably sharp up close
As we have shooters on Cake using a very wide range of brands of cameras it will be interesting to see what the preferred pancake lens is, as a single grab and go lens and of course images would be a bonus to see how your lens does in the real world
