eerrm.. where's the focus point?
eerrm.. where's the focus point?
You may refer to the review of 70-300mm ED VR by Thom Hogan below. According to him, this lens usable at 300mm, but this is where this lens' performance is at its weakest in almost every respect.
At web size can't see anything sia.
Need to see 100% to be 100% confirm
Well, 70-300 is quite a "standard" focal range. I'm sure Sony makes a lens of that range as well. I notice that for the D90's shot it was 1/1000s shutter speed, whilst on the Sony it was 1/1250. Any reason for this discrepancy?
Also, ISO speed not stated for the shot taken by Sony.
The shutter speed that I av overlooked, thanks for the highlight
By the way A55 is also at ISO 1600
Photo A seems slightly sharper to me.
But honestly speaking, both look sharp enough at web sizes and the difference is small enough to be negligible. Besides, many other factors like focal point, aperture, technique etc, will affect sharpness.
What is interesting to me is the different colours produced by both brands, the Sony looks better to me. Of course, this is irrelevant if you shoot RAW, or bother to tweak the JPG output on the Nikon.
May I ask why you want to make this comparison?
A is sharper. B colors look more realistic. A's tone seems to be more on the warm side. Both sets in awb?
The yellow color of the crane and the green safety cross looks like what I would see with a naked eye.
Although im a canon user, looking at the number of thread in this forum, you can't go wrong with nikon. If you are the kind who upgrade, do consider the market share of each brand as it will affect the resale value in the future...unless you are the kind who like collecting lens/bodies.
If the above is not what you are looking for then as many have mentioned. A is sharper. But seriously se little point in stating that. Good luck.
Canon 550D - EF-S 18-135mm f3.5-5.6 IS / EF 50mm f1.8 II
Sigma 70-300mm F/4-5.6 APO DG Macro
Har? So in the end "which photo is sharper" was simply "should I buy Sony or Nikon?" hidden in disguise?
Photo A has more contrast colours. I don't think sharpness is a concern here, because both is sharp. Both photos are in focused (I used the crane as a comparison since the human subjects are in different positions). I do not want to flame anyone, just saying my honest opinion. If you want to do a sharpness test, try to keep it at 100% crop and the subject you can help us to focus on. That will do help for yourself and other forumers to make a proper comparison and better judgment.

Just some points to add, do not just focus on sharpness, there are other factors which makes a camera a good camera if you weld it well. Features like AF speed, dynamic range, high ISO performance, body built-in vibration reduction, remote trigger of off-shoe flash via onboard flash (CLS), etc
Fist thanks for your comment, may I know what do you mean by " keep it at 100% crop", how can I do that or how to acheive that.
Thanks as I don't quite understanding 100% crop, do you means that I have to say focus at a wording on the crane then crop only the word out to compare instead of looking at the whole photo to comment?
Thanks and your advise is greatly appreciated.
