You can change absolutely nothing and get slightly different results each time you rack the focus.  When making a change you should rack the focus and take at least 3 test shots changing nothing. A ...

There is no reason for me to apologize.  I only pointed out that you haven't used the lens in the field and your opinion is based on DXOMark scores. If you are going to base a purchase on online ...

Ok, so you are basically basing your opinion on DXOMark scores along with a ridiculous video review of the D750 in which some guy just stands in front of a video camera and quotes DXOMark scores.  ...

Enjoy.  BTW - D5500 pics # 3 and 5 appear overexposed to me.

Are you basing this opinion solely on the DXOmark scores?

Blanket statements like this could be inaccurate.  How can you be sure you are not seeing an issue with your particular combination of camera and lens.  FWIW, my 24-120F4 is very good at 85mm, ...

I have both the 24-85VR and the 24-120VR F4 and the zoom action of my 24-85 feels significantly cheaper than the zoom action of my 24-120. With that being said, the two lenses return nearly ...

Be aware that an AF adjustment that works well at one focal length and/or distance might result in worse performance at another focal length and/or distance.  You should test multiple focal ...

I have one and it is very good on my D800.  Can you post some samples?

I travel with a D3300 or a M43 camera.  A D3300 with an 18-55VR or a 35mm prime is _much_ smaller and lighter than my D800 with a similar lens in FX format.  A D500 is not much smaller than a ...

I don't think there is anything wrong with your equipment. Both of your shots were taken with the lens wide open and at fairly slow shutters for dogs at 105mm. If the dog moves the image will ...

Ok, please realize that I'm not attempting to criticize your photo.  You posted your sample on a gear site so I just commented on the technical aspects.  The important part is to keep having fun ...

Maybe my eyes are going but this image looks pretty soft to me and the color/contrast is nothing to write home about.  Your combo should be able to do better.

My thought process is the 300mm lens provides an optical image that is more magnified than the optical image from the 200mm lens. Furthermore, the FX image with more optical magnification is ...

Assume we have a 200mm DX lens and a 300mm FX that are both of equal optical performance.  Mount the 200mm DX a D7200 and the 300mm FX on a D750 and shoot both in good lighting.  DOF aside, would ...

I understand your point and my previous post said this -> I do realize that my D800 is "only" 15MP in DX crop while my D3300 is 24MP at the same FOV and some might consider the higher MP count in ...

DX does not really provide more optical "reach", it just crops the FOV.  I do realize that my D800 is "only" 15MP in DX crop while my D3300 is 24MP at the same FOV and some might consider the ...

The D7200 kit 18-140 kit lens should be plenty sharp. Maybe you got a bad copy or maybe you have something set wrong. FWIW, I get sharp pictures with my old Nikkor 18-200VR (Ver1) on my D3300, ...

That is a nice one.

Thanks. It sounds like the Adorama book offers the best print quality.
