Panasonic GH5 Lenses - Native or Adapted?
When I bought my GH5 back in March 2017, one of the most frequently asked questions I saw was "Should I buy native lenses or adapt Canon glass?" Before my GH5, I had a Canon 60D, but I mainly had EF-S glass, and one Canon 50mm f/1.8. I wasn't very invested in full frame Canon glass that everyone adapts to Micro Four Thirds.
So I decided to go native for it's reliability, small size, price, and stabilization. First two lenses on my list were the Panasonic 12-35mm f/2.8 and Panasonic 35-100mm f/2.8, seen below. These two lenses on a Micro Four Thirds sensor have the equivalent focal length of a 24-70 and 70-200, which is a very popular combo. If I had to choose any two lenses again, I would pick these two, except maybe opt for the Olympus 12-40mm f/2.8.
I also bought both of these lenses used. Since the Mark II's were about to release, it seemed like everyone was trying to get rid of the Mark I's, even though they didn't change much in the Mark II versions. From what I remember, the Mark II's have Dual IS 2.0 and are all black.
One of the biggest reasons I went native was because at the time, the Metabones Speedbooster was having problems with the GH5 and the infamous Sigma 12-35mm f/1.8 that everyone loves. Eventually I'll start investing in Canon EF mount glass, but for now, these two lenses are more than enough.
The one problem I have with the lenses and with Micro Four Thirds in general is the low light capability. Which is why I turned to Canon FD.
Canon FD 50mm f/1.4 - Low Light Capable
This Canon FD 50mm is one of my sharpest lenses. At f/1.4, it's a little soft, but in a low light situation, I'll take softness over boosting my ISO in order to get the shot.
This lens is also pretty cheap. Looks like it's going for about $75 on eBay, which is nothing for a lens this good! I scoured Craigslist looking for someone trying to get rid of their old Canon lenses. Luckily I found a guy an hour away selling a whole set of them for about $100. Along with this, it came with a second 50mm f/1.4 (he couldn't remember why he had two), a Canon FD 24mm f/2.8, and a Vivitar 75-260 f/4.5, which is an insanely huge lens.
Anyways, using this lens with a "dumb" adapter makes it a 100mm lens, but with the GH5's IBIS, it's really easy to shoot handheld with it. I love it.
