Looks more like a difference in post processing to me. Yours looks more sharpened and much noisier and more posterized. It's also a higher resolution file.

Here is the jpeg straight from RAW conversion, no other pp applied and about a 50% crop. Not my fault it is a higher resolution file. Sorry about the terrible noise and posterization.

Those are better processed for the noise for the most part. There is something seriously going on with your GBH shot though, nasty noise and lack of detail, it looks like you might have tried to raise the shadowed area a bit too much in brightness. Anyway it still just looks like the difference is nothing more than a matter of post processing, you seem to be more comfortable with the sharpening slider than I am.

You've got to be kidding. The image is as "quiet" as the GBH flying in the distance

I'm just telling you what I see on the displays I have available. Yes the background is nice and noise reduced but if you look in the area under the wing that is facing the viewer there is some serious nastiness like a shadow that has been lifted too much. That is what I see if I'm being honest.

Well we all see what we want to see, and we have different monitors. What I see is that the images I posted show more detail and no more noise than your hummer shots.

But just for you, I cleaned up the GBH as bit.

I look at all my photos and want to see them look better, but it never works.

As long as it's working for you. I know if I don't look at my images with a critical eye I never improve.

A zoom is not a 600mm lens, nor is a 400mm lens with a TC. Neither Sigma nor Tamron makes a 600mm lens.


Sigma have made a 600mm f/8 lens. It is a mirror lens, and they no longer make it, so you still have your words correct. In fact, I did not try to prove you wrong, I just answerd the question:

And what makes you think f6.3 is perfectly normal for a 600mm lens? The best 600mm primes are f4, and nobody even makes a 600mm f5.6 that I am aware of.


To that question, what makes me think f/6.3 is perfectly normal for a 600 mm lens, I think what makes it normal is what apertures people actually use to take pictures at focal lengths approximately 600mm. It is irrelevant if they use zoom lenses or teleconverters or pure 600mm prime lenses currently made, as long as what they use are real solutions people compare for prize, weight and performance.

Even if I think f/6.3 is slow for 400mm, I perfectly understand why it is made and why people buy it, I just think it is slow for 400mm.

Of course it is slow for 400mm. That is why it is at a price that many can afford.
