I was reading in details PZ reviews for Nikon 70-200 F4, Nikon 70-300 VR and Tamron 70-300 VC and based on the resolution analysis, they don't seem too much far apart.

Then on the DXO lens comparison on the D800 camera

Nikon 70-200 F4 has Sharpness of 21

Nikon 70-300 VR has Sharpness of 11

Tamron 70-300 VC has Sharpness of 10

and Sigma 70-300 OS which should be the worst (by far based on PZ test) has Sharpness of 11

How is that possible?

Also when I look at just the MFT numbers from PZ test in 70-200 range, 70-300 lenses look pretty good compared to 70-200 F4:

I made even bigger table (with more interesting lenses) - perhaps you will find it usable:

and also the same in PDF:

Markus, Klaus, other knowledgable lens testers, can you please cheap in a little bit please?



based on the numbers nikon and tamron 70-300 looks quite good in comparison to 70-200 f4 (I am looking for lightweight zoom in 70-200 range).



It seems to me like Nikon and Tamron should give about 90% of Nikon 70-200 F4 performance, and prices here in Canada are:

$440 CAD for Nikon 70-300 VR

$450 - 100 MIR for Tamron 70-300VC

and

$1300 for Nikon 70-200 F4.



I already have Nikon 85 F1.8 and Nikon 300 F4 (non AFS)

So this morning I was thinking 70-200 F4 for 1300 or Tamron/Nikon for 350/450 - it is almost 1000 difference (with the tax it will be 1000). For 1000 I could get used Nikon 180mm F2.8 and flash (SB900/910) and even perhaps 50mm F1.8 Smile

Can you please share your thoughts?



thank you in advance

yours truly
