X1 lens behaves like what it is

Hi everybody,

 

The X1's 36mm-like field coverage cannot fool the eye. The lens images depth exactly as it should do, rendering perspective like a true 24mm wide lens. Next time, try a scene with some vertical objects along the line of sight.

Do you mean that the lens distorts a bit? If so, yes, but easily fixed with LR even though you lose a bit of sharpness as a result. But the field of view is still 'normal'......

Perspective depends on distance to the subject, not focal length. To capture the same field of view with X1 as you would with a 36 mm lens on an M9 (or any other 35 mm camera) you need to keep the same distance, therefore the perspective will be the same.

 

Apart from perspective (which has nothing to do with lenses as such) there may be issues with projection and distortion, but these don’t strictly depend on focal length either.

I didn't intend to do a "physics" analysis. All I meant was that, when looking at the foreground object on the X1 screen as contrasted with the far background objects, the impression is that of a wider than 35mm focal length lens.

I don't own a 24mm SLR prime lens, but I use the 28-90mm on my R6.2 and the X1 projections of the far distant objects are more like with the 28mm than with the 35mm focal length.

But again, it's all an impression maybe. And, by the way, I see no noticeable distortion--that must be due to the 1.3 cropping.

 

Thanks

The X 1 lens behaves like what it is, a 24 mm lens. Nothing changes by the crop camera with exception that we see a cutout of a pic, made with a 24 mm lens.

With regard to depth of field the the lens of the X1 corresponds roughly to a 29 mm lens on an M9 (at the same f-stop). That is, DoF isn’t quite as large as it would be if you used a 24 mm lens on the M9, but larger than that of a 35 mm lens.

I know what the OP is getting at and maybe it has to do with being an Elmarit. It is a very sharp lens but does not produce distinctive out of focus areas even wide open at minimum focal distance. A 28 Elmarit on my M8 renders in the same fashion as the X1. It's more the look it produces rather then the actual focal length.

The OOF areas in X1 photos are very pleasant, not like the lux or cron but pleasant.

Being an Elmarit entails having a lens speed of 1:2.8 and nothing more.

So every lens has the same signature at corresponding apertures? (28 summicron @ 2.8 vs. 28 elmarit @ 2.8)?

 

Phancj - the X1 does have a nice OOF for what it is, I've gotten a lot of nice shots with it.

Not generally, no. I just wanted to point out that there isn’t really that much in a lens name – 1:2.5 and it’s a Summarit, 1:2,8 makes it an Elmarit, 1:4 an Elmar etc.. There is no such thing as a typical Elmarit signature.

Hallo,

The 24mm on the x1 "behaves" like a 35mm on fullframe or a 50mm on medium format, when one shoots it at the same distance.

The only difference is that the wider the lens the more DOF will you get when using the same f-stop at the same distance. (Plus of course chracteristics of the specific lens).
