Paul, where are you getting your 24 x 16 paper? :o

 

Following Jaap's valuable suggestion for printing MM files on Canson Bayrta Photographique, I have started using it for everything.... But I stick with the R3000 borderless because I do not see 1:1.5 paper in sizes larger then 13x 19. What have I missed?

 

Thx,

Peter

 

Depends on the project really but my lab prints up to 120 inches on Fuji Crystal Archive, Kodak Endura, Duratrans, Ilfobrom Gallerie FB or ILford RC printed by Lightjet.

 

The backlit duratrans have to be seen to be believed.

My guess is that Sony has intentionally crippled third party lenses by using a thicker filter. Why would they not? I had suspected they would do something like this from the beginning to make you buy their lenses designed with the entire sensor module in mind.

 

 

I am not willing to make any assumptions and simply hope the cover glass will avoid any IR issues. ;)

CV 35/1.2 @ f/1.2 on a7r

I'm sure everyone is aware this is the fastest 35mm lens ever made for 135 negative. Do some peeping and you may be surprised at the sharpness wide open.

you can find more samples in the same set. :)

 

I see it begins to seep in here that the Sony performance is unmatched by Leica with some lenses, while inferior to Leica with others: though it should be said the A7r has superior central IQ nearly with all M lenses. Sony rendering is beautiful....

 

.

 

Yes it is very sharp at F1.2 indeed. But now that we are looking at 36MP images at 100% we also clearly see how paper thin the DOF is. Maybe we will be shooting stopped down farther than in the past to get enough in focus.

I see some flare issues in the reflection of the sun in the cat's iris.

 

Fail.

 

;):rolleyes:

 

 

You forgot to mention the horrific chromatic aberration there as well! :eek::rolleyes:

I am amazed Rick hasn't pointed that out by now.

He is probably to busy fondling his A7R.

Yup. Just from practical experience on the M240 I've not been at f/1.4 as much as with the M9. Now with the Zeiss 35 on the A7R I'm not missing f/2 to be honest and the shutter is up at 1/250 mostly.

I guess I have been saying this in a roundabout way a few times. On very high res cameras I really wonder what the utility is of fast lenses except for some special purposes since many people will just see the image as being un-sharrp.. Not everybody appreciates "beautiful bokeh." And if you are not going to use the image real large, a lower res camera will suffice.

 

On 4x5 I generally was at F16-F32 and could have had shallow depth of field quite easily, but didn't go that route very often. I think there is now a dichotomy between using 35mm as a fast expressive camera and using it like a hand held view camera.

I've been thinking exactly the same thing as I've been looking at some of the samples I've been shooting, the DOF is extremely thin. You can see this on Ronaldo's head, and hair on the back of his neck.

Ahem....DOF is an optical property gentlemen, not a digital property. ;)

 

Right. But we didn't typically use this level of magnification before. At higher magnification the falloff of the sharpness becomes more apparent.

Peeping has evolved I give you that.

 

50Lux at f/1.4 @ 3 meters will have identical DOF on 135 film, M9 and A7r. Obviously rendering will vary. :)

 

My shot above is unusual in that it is taken with a hawks close focus adapter.

 

again 35/1.2 well this could be 1.4 :(

In thinking about this and the Lytro light field concept, I wonder if other approaches will develop. For instance as technology evolves, I can see a system that shoots two images in rapid succession... one wide open and one stopped down a lot. These could be stored in a single file and you adjust the sharpness falloff selectively in post. It is similar to focus stacking and some HDR techniques.

 

This certainly is doable today when working on a tripod shooting still objects. Another reason why Leica may want to electronically link their lenses to the body and control those lenses from the body.

A7R is here, but alas, I'm at work. I did bring the 50 Summilux with me and so far grab-shots seem very good. I probably won't have time to really shoot this little beast until the weekend.

 

Also, the box isn't half bad either. Certainly not up to Leica collector status, but functional.:rolleyes:
