I find lens correction can make some portraits less flattering if pincushion is removed from the long axis in portrait orientation but will benefit if its a horrizontal format.
so i usually leave lens correction off uless i want it then just click it if i think it will help sometimes its good sometimes not. I definately dont have it applied to everything

You are welcome, I was out shooting but was amazed nobody jumped in with an answer for that, Lightroom is so powerful and considering the amount some people here shoot, literally thousands of images per shoot, I'd expect a robust preset strategy to be basic necessity and a huge time saver.

I only find the serial number setting useful when shooting with different bodies of the same model and their exposures are out compared to each other, then a basic exposure preset will even everything out.

I'm well under way now, I've enabled luminance NR at a fixed ratio, ie iso 400=8, 800=16, 1600=32 etc. The noise on the Nex 6 is quite nice, looks a lot like film grain so I'm not bothered with adjusting color noise.

However to set NR I need sample images at each iso - an inconvenience to say the least. I haven't been able to find a settings file where I could define this, such a shame because it's easy to miss out on NR settings for intermediate iso's this way. I don't suppose you know if this can be configured by editing a settings file by any chance?

I'm not buying another "fast" wide angle lens until a manufacturer can offer me near-zero coma and near-zero CA. My Sigma 35mm f/1.4 was a *horror* in this regard at f/1.4; the only useful portion of an astro image was perhaps 10% (at most) near the center. And if a lens can't shoot cleanly at f/1.4, I don't think they ought to advertise it as such. My Sigma 35mm was only useful at f/2.8 and above. At 1.4 it was a joke.

As consumers, we've been far too forgiving of these horribly distorted lens designs. Here's hoping the manufacturers are listening.
