Hi all, firstly please forgive the length of this 1st post but I figure more information is better than less and I am intending to cut and paste this to both M4/3rd fans and to some DSLR / EOS forums as I want to get all perspectives. The short version is I am trying to capture low light, non flash, bar life, candids.. Down and dirty in the neon !! So fast primes fairly wide. I am connected to a bar in Phnom Penh and want to keep producing shots of the bar and staff for facebook / social media etc. Also this type of night low light photography is a niche I really like to see, have always wanted to take, but have always struggled to capture. Recently I used a Canon 5D Mk3 with the 50mm f1.2 prime and just WOW.. I came away from that ready to upgrade there and then. Thankfully I have had a cooling off week but still want that or closer to that kind of image capture. The long version I guess starts with what I use now and what doesnt work for me. My walking around snapper camera is a s95 which I am pretty happy with as a well lit snaps cam it is f2 at wide but its not fast enough to work without a flash much in the context I mean here. I also have a Canon D450 with a couple of zooms and the F1.8 50mm prime. This of course on the D450 APS-C sensor has a 1.6 crop to make it equivalent 80mm and I dont really know what that does to the F Stop. The DSLR is my 'better camera' and for everything apart from this type of shooting its enough for me. Of course the DSLR and lenses is big, a pain to cart around, and hence gets left when a smaller camera might come, but even the M 4/3rds systems with a decent lens present something to carry rather than pocket. Still the actual use of the DSLR is low, something I am thinking about when I consider dropping multi 1000 USD on a better 'better camera' !! Another thing is a 5d and large lens gets attention, your subjects pose, its hard to be discreet, all those reasons are factors in the size game as much as the physical of it. I am not a 'serious shooter' and am far more likely to be in auto than full manual.. I am not a pixel peeper, I dont print high resolution and I am not much of a sharpness nazi for lenses.. So I should be pretty easy to please right ??? The problem is, I want to take handheld shots in very very dim light, without flash, candids of subjects who are working and while not high speed, are not fully still either. Those kind of images with that multi point glow from every light source around a room. I had been struggling to achieve these kind of shots with my f1.8 prime, I would say I was getting only about 30% of my shots clear, without some shake or blur and while I can just spray and pray its annoying to lose good moments because your not steady enough or the subjects movement. I was turned on to a neat cheap trick of using a LED key chain to spill a little light and have been experimenting with yellow and red ones which cost almost nothing, but then like I mentioned above I had 2 minutes playing with a 5D Mk3 and f1.2 50mm prime. For a start the real 50mm width on the full frame sensor opens up the room, and the ambient glow that comes from all the surrounding light sources just made some great shots. Overall I guess about 80% of the shots came out sharp enough to use which is a massive difference in hit rate for me. After having such success instantly with that, I have spent the next week trying to look at my options and think how best to improve my equipment to get closer to those shots. I hadnt been in an upgrade mindset for a long time and while I knew the M4/3 scene was getting good, I was just out of the loop and didnt know about some of the faster lenses now out (25mm f1.4 summilux or even the manual focus 25mm f0.95 voitlander). Theres been a few days of reading so far. Just for reference what I am trying to achieve are shots like this.. I should also note that despite these looking bright and well lit, this is in a very very dim bar, mostly lit by LED rope lights, with just a little white light at the bar for staff to see well enough to work. Not only that ambient glow which is my primary goal, but lovely shallow DOF to isolate the subject and blend background with bokeh. While those look brightly lit taken with any other camera tend to show that its a dimly lit room with a couple of 5w red bulbs and rope lights !! Basically, can any 4/3rd system and lenses get that ?? If so at what cost in money, complexity, etc. The way I see it I have 3 clear options. Keep the d450, spend modestly more money on either a f1.4 50mm prime (about 300 something USD) or the very nice f1.2 50mm prime which at 1500 or so USD seems a bit dumb on a APS-C body. While this isnt so expensive to do I dont know if it can really capture those shots I want ?? So then the next step up (or down the slippery slope) is a 5D body and either of the above lenses.. The full frame sensor should open these lenses up and if I wanted to be economical I could look for a clean 5d MkII.. Even so this is rapidly heading to 3k usd for this setup used and easy to double that with a new 5d Mk3 and some lens choice. Now the money isnt the biggest problem but less is always good and I also dont want to be 'that guy'.. The guy with the uber expensive kit that barely knows how to, or actually carries it about, to use it. I am not a mad keen photographer more a happy shooter and 5k I dont spend can easily be used in other hobbies like a new dirtbike or just plain old fashioned wine, women, and song. Lastly is the area I know the least and am asking the most about. Can any smaller compact systems produce shots that are as good as, or approaching the shots above ?? I mean an LX7 may have a f1.4 lens, it may let enough light in, but that small sensor is not going to give me anything like the same DOF in the short bar distances I will be shooting. I have in the last couple of days read about f1.4 25mm prime M4/3rd lenses which are cheap (compared to the above ideas) enough and even the Voitlander f0.95 25mm prime manual which interests me greatly at ballpark 1000 usd. Any of these could be paired with something like a nearly disposable cheap used GF2 body or to gain the viewfinder a GH2 body or any one of a selection of 4/3rd systems (I really havent yet dug into the bodys yet I have been mostly checking the lens options) and the specs say it should be impressive at total costs of less than a single lens on the canon full frame route. But specs aside for all my digging on flickr I havent found any / many shots that are like I am trying to capture.. Can it be done ?? Is what I want to shoot possible with these systems. I was also told to check out the fuji x Pro1, which looks like it would work as a 35mm prime only setup, let lots of light in, but again, DOF ??? Its also not a cheap setup with a pretty narrow application even if it does seems like a quality item. At least with M4/3 and other lenses it could serve multiple roles while that seemed to me a bit one trick pony. Nice one but not sure.. So if you have read this far then thanks, even more so if you have any suggestions or avenues of research. I have been reading so much my head is spinning.
