One of my few complaints about my GH1 is the relatively poor high ISO performance compared to a number of the dSLRs now on the market. This is exacerbated by the fact that thus far I only have the kit 14-140mm lens, which at its widest only opens to f4.0 and so I end up using a higher ISO setting than I would prefer in dim light. As a result I've been looking at noise reduction software. (Yes, I plan to purchase the 20mm prime but that's a little ways off.) The "big names" in noise reduction seem to be Noise Ninja and NeatImage, but yesterday I became aware of a competing product called Topaz Denoise. Several separate online reviews indicate that this product is much better at retaining fine detail for a given level of noise reduction. I've downloaded the free trial and will be experimenting with it. Being new to noise reduction software, I'm not sure I'll be able to do a good comparison in the short term. So I'm curious if anyone here is using Topaz Denoise with a Panasonic mu-43 camera. If so, what have your experiences been like and do you prefer this product or one of its competitors?
