I've always had zooms with my Canon gear. I prefer wildlife photography to be honest, but having such a young family I realise that having free time just isn't going to happen any time soon. So for now, family/landscapes are the short term future ( 3 years or so ). I'll probably get a 7D3 and Sigma 150-600 Art in a few years when I get some free time back from nappies/bottles/spoon feeding
I'd rejected the 16mm/1.4 due to it being so close to my 18/2, I did consider it initially with the 56/1.2 and my 35/1.4 in the middle. When I say family shots I meant outside as we walk a lot with the kids. I thought 23mm was better for those type of situations.
Someone had posted they felt their 16-55 could replace their primes which had me curious.
I took my X Pro1, 18/2 and 35/1.4 out yesterday in a shoulderbag, and hardly felt it was there. It's so easy to slide it round and get a body out. In the last few years I've taken my 7D, 16-35/4 and either my 70-200 or 100-400 and never even taken my rucksack off due to it being so cumbersome to get it out and maybe swap lens. So, I've lugged it around all day for nothing. My 70-200 hasn't taken a 1000 shots, neither has my 16-35...............
Just analyze your style of shooting. As you will see majority of all the photos on this thread are natural light be it indoors our outdoors. This is where I find the fuji system to excel.
I have seen very little events photography on the POTN using flash.
What is tough for me to do is shoot fuji turning off the exposure preview. Shooting mirrorless the strong points is wysiwyg and shoot away with almost perfect exposure. If you turn off exposure preview you'll need to chimp just like using a traditional mirror camera using flash.
I can't see a fuji 16-55 replacing primes if your indoors. In fact even my 27mm f/2.8 is not fast enough for indoor photos in home. Casual snaps is not a problem but for serious shooting fast zooms/no flash cannot reap high keeper rate IMO.
A 35mm equivalent is probably a nice fast prime for outdoors vs 50mm equiv. In my particular style I dumped the 35mm FL (canon) as I found it boring compared to getting killer neat perspective with a UWA lens. This is all subjective and personal..........
Just remember when you analyze photos to see if it's action or stationary/slow moving. Flash is still Fuji's extreme weak points.
