Hello all,
I produce high-resolution Milky Way pictures, mainly using my Pentax 645Z and 25mm f4 lens. The results are good, but due to the f4 lens, I am generally using ISO6400 - so noise (while amazing) is still an issue. Since the advent of the Sigma Art 14mm f1.8, I am wondering if the D850 might allow better results. Although the sensor might not be quite as good in itself, the ability to use faster apertures would allow the use of lower ISO which might produce better results overall. The pixel count is similar.
But then I noticed that the D850 seems to be coming up in tests with somewhat poorer results at high ISO than I had hoped for (though I am wary of tests!). Some people are suggesting the camera is optimised for performance at lower ISOs and perhaps the D800E/810 may be better at high ISOs (even allowing for lower pixel count).
So the question is, which full frame DSLR camera would produce the best overall results in the ISO range 1600-3200? Taking into account noise, resolution and any other factors. I am prepared to trade pixels (by using D800E/810) if the noise is much better than the D850. In the end, it's the 'clean detail' that is obtained overall through resolution and noise, etc. that I am looking for. Do I dismiss the D5 because, while there is probably less high ISO noise, resolution is also much lower.
And (<<gulp>>), would any other manufacturers' cameras provide anything better still for this precise application?
Any views/data/examples to help?
Thanks,
Ed
