La maison du pêcheur Ce carrelet blanc tente de nous montrer la ligne d'horizon caché par l'épaisse brume qui régnait ce soir là.
Une photo léchée, efficace Le moulin Plessard L'un des plus beaux sites près de Clisson, sur cette photo j'ai laissé la teinte originale de couleurs oranges. Baguettes magiques Voulant prendre un couché de soleil sur les Marais Salands de Guérande, j'ai tout de suite percu le potentiel de ces branches qui dépassaient de l'eau.
L'eau du marais saland était d'un calme religieux et le dégradé de couleurs sompteux. Il ne fallait donc pas rater cette photo qui malgré ses origines Bretonnes marquées a une consonance chinoise ; non ?

Use case of this test : nikkor AF-D 50mm f/1.4 vs nikkor AF-D 50mm f/1.8:

This test has been made with two different Nikon D70 in jpeg mode resolution max (6 millions pixels) with the same menu parameters, color sharp ..
The 2 D70 where put on a tripod very near, all the photo have been shoot whith respectivly same focal and same shutter speed (per focal).
The house was in front of us about 10 meter and the photo have been shoot at th same time.
I have choosen to have an small angle inclination with the wall to avoid some questions about Back-Front Focus. Originals jpg files (full size) are on line, so you can see it by your own : results are more surprising in full size.
Thanks to régis for his contribution.
All pictures below are crop of the full size jpg at the point where focuse has been made

Lens

Nikkor AF-D 50mm f/1.4

Nikkor AF-D 50mm f/1.8

Comment

f/1.4


50mm 1.4 f 1.4

We can note that the 50mm nikkor on f/1.4 is already good. Sharp is the same as the Nikkor 50mm 1.8 on f2 almost f2.2 !

f/1.8


50mm 1.4 f 1.8


50mm 1.8 f 1.8

The 50 1.8 is very slackness whereas the 50 1.4 is already very good. (Out Of focus ? I purposely took the photo with a certain angle even if there were a shift of focus, it is forcing good some share on the wall, therefore by taking the image full size (just by a click) it is very easy to see that the 50 1.8 is less sharper that the 1.4)

f/2


50mm 1.4 f 2


50mm 1.8 f 2

On f/2 the 50mm 1.8 is a little bit shaper but the 1.4 is more an more sharper...

f/2.2


50mm 1.4 f 2.2


50mm 1.8 f 2.2

on f/2.2 the 50mm nikkor 1.4 is already almost its max sharpen, the 50 1.8 is not.

f/2.8


50mm 1.4 f 2.8


50mm 1.8 f 2.8

f/2.8 the 50 1.4 is on its max sharpen that's why it is an very luminous lens because a classic lens which begin on f2.8 will be on its worst sharpen.

f/3.5


50mm 1.4 f 3.5


50mm 1.8 f 3.5

the 50 1.8 is near itx max of sharpen but not as good as 50mm 1.4... But we enter in the range of standards apertures ...

f/4.5


50mm 1.4 f 4.5


50mm 1.8 f 4.5

At this aperture we can say that the two lens are equivalents

f/6.3


50mm 1.4 f 6.3


50mm 1.8 f 6.3

No visibles differences between nikon 50mm nikkor 1.4 and 1.8

f/8


50mm 1.4 f 8


50mm 1.8 f 8

No visibles differences between nikon 50mm nikkor 1.4 and 1.8

f/10


50mm 1.4 f 10


50mm 1.8 f 10

No visibles differences between nikon 50mm nikkor 1.4 and 1.8

Bilan du test:

Nikon nikkor 50mm f/1.4 cost (on 2005) about 230$ in HongKong (via ebay + tva) and 100$ for the 50mm nikon nikkor 1.8. Quality construction is better on the 1.4. The lens is bigger on the 1.4
I take pleasure with the 1.8 while many month before to do this test and to sell the 50 1.8 for the 1.4 ;).
