I see that not just you but a lot of people use m43 for travel. Is this because of the smaller lenses and less weight? Wouldnt that be a hinderance in low light?? (i mean the fastest prime is actually like a f3.5.
You can see in my Gear List that I have both systems. The difference in size and weight between FF and µ4/3 is enormous. Many of us have traveled with FF systems and had an aching back by the end of the day. OR, we brought fewer or inferior lens options.
We have found that µ4/3 gives very good results. Not as good as FF in low light or DoF control, but more than good enough to forgo carrying the heavy gear.
Opinions will vary and there will always be those people who feel it is ALWAYS worth it to carry the heavy gear, but I'm not one of them. (any more) Please note that I'm only 44 years old and in reasonably good physical shape.
What also comes into play is whether, when you travel, you would rather:
- Enjoy the travel experience, or
- Document it with the best technical clarity
Hence my "split vote" option. When I travel, it is with my own money with the primary goal being to experience another culture, not to make it into a photo expedition. I (no longer) have no delusions of being a National Geographic photographer. ;-)
***********
As for whether it is a hindrance in low light, I would say no. With my particular systems, in low light, with relatively static subjects, the outstanding IBIS of the µ4/3 system, combined with a fast lens is as good as the FF system without stabilization or with a slower, stabilized lens.
If have low light AND subjects in motion, I just have to take my lumps. Shoot at higher ISO in raw and de-noise later, if needed.
To me, the superiority of FF in low light is a much lesser concern than the DoF control of FF. I can't afford the f/1.2 PRO lenses in µ4/3, just to get to the DoF control that an f/2.8 lens will give in FF. It sounds like it's picking nits, but it's really not. In FF, even at f/5.6, with a short telephoto, we can see truly limited DoF. With a slow f/4 or f/5.6 lens on µ4/3 , it's like f/8 or f/11. Useless. You really need the fastest optics or the right conditions to limit DoF in µ4/3.
By the way, when I got back into FF, I was toying with the idea of selling off my µ4/3 system, because of the superior DoF control. But in the end, I decided to hold off until I can travel again, as that is where µ4/3 really shines. When I do travel, it will be a choice for me of:
- Nikon D610 w/24-120/4 VR, [3 lbs., 8 oz.] or
- Olympus E-M10.3 w/12-60 (24-120), 17 (35), 40-150 (80-300), 9 (18) [2 lbs., 11 oz.]
...with the Olympus system STILL coming out way ahead, in terms of weight, and bulk is about the same.
