So many speculations... I hope that S3 arrives soon and implicitly answers these questions with stable facts and performance. In the End the S system is to regard as a designed and well thought thing that combines subjective feelings of the user with technical and ergonomically aspects.

I’m well aware of the criticism regarding the zoom performance, but thought that the feedback on the 70 Summarit was quite positive. Have I missed some discussion or consensus?

Jeff

 

It is a good lens, but in my experience, it has significant field curvature that makes it difficult for me to use for landscape work below f8 (which is generally not an issue, except at night). Other S lenses do not exhibit this behavior, at least not badly enough for me to generally notice. The 70mm does. This may be highly dependent on the kind of photography I make...Iceland features a lot of landscape features that are fairly distant and at roughly at the same distance from the camera (mountains in the distance for example), and in those compositions I find it bothersome, so I tend to stick to the 45mm and 120mm lenses at night, or keep the 70mm at f/11. It is possible this is only my copy, but I did return it to Leica explaining the issue, and they returned it to me saying it was in spec.

Some general S lens performance challenges noted in this thread...

Digiloyd noted possible S70 field curvature as well...

Still, other than perhaps the zoom, most here seem to rave about the practical results from use of the S with all its native lenses.

I don’t have issue with 70mm performance and I know myself quite critical about sharpness for landscape stuff. The zoom is also very nice and get nice corner after f8.  I don’t know why it get poor reputation but I think focus problem is bigger issue for these S glasses. You either use LV check cross frame to optimize your results or need watch out barrel location in field, don’t trust Leica’s AF.

If you look MTF if 70mm, at F5.6, it is already above 60% at 40lp/mm cross frame. That is awesome performance. Even there is FC, it is really should be minimal at 37M MF sensor. Equivalently Resolve 24M FF sensor is a piece of cake after f8 I would say.

Yes, I do not what the issue is either, but it is there. The problem is not always being very unsharp, it is uneven sharpness...having something going from incredibly sharp on center to slightly unsharp on the edge...in a way, the extremely high performance on center is working against you because it makes you notice the less than perfect performance at the edges. I know for my 30-90mm lens at least, that there is no aperture at which I can get critically sharp edges when longer than about 65mm. It is not a matter of focus, although I do find the focusing pattern of the wide angle lenses to be consistently short in a lot of compositions.

Anyway, you can have a look at two pictures that show the issue I occasionally have. They are full sized jpegs though, so I need to use a dropbox link. I should say that in general these photos are sharp, but this kind of sharpness can be troublesome in very large prints, which I occasionally make. In general, however, I like the lens and can work around these issues. I would love, however, to have a smaller standard lens where I did not have to think about this.

Slightly closer to the topic, I had a chance to try the GFX100 yesterday in the shop. It seems like a superb camera, and quite nice in many ways. I do not think it feels nearly as good as the S in hand, nor does the EVF come close to the optical viewfinder in the S. I look forward to seeing the S3 in person, but so far, Leica is still far ahead in terms of handling and ergonomics, at least to my hands.

Until I handled an X1D.  For me , the S OVF is its core differentiator, apart from any IQ opinions or lens debates.

So Jeff, do you like the X1D? I wouldn't mind the form factor and I think it's a pretty camera, but I wouldn't like to miss my OVF.

I’ve tested it (made prints) twice, as I did with the SL and S006 (only briefly S007).  Each has pluses and minuses, of course subject to personal tastes and preferences. I love the S ergonomics and interface/controls, and especially that beautiful OVF.  The X1D has  a fantastic form factor, one of the nicest modern cameras I’ve handled (shooting since the 70’s). And the touchscreen menu is simple and requires no instructions.  But I’ve never been a fan of EVF viewing, although there are undeniable advantages to on-sensor focus and display options, etc.  Additionally, I didn’t want the first generation X1D despite the many FW fixes. I’m looking forward to testing the latest iteration and reading about any lingering issues.  But at the price point, and with the new zoom, I could be a buyer.

Got my GFX100 last Thursday with the 250mm f/4 and 1.4x.

The IBIS is really blowing my mind. pin sharp image from 45mm f/2.8 at 1/20 hand shot and the support from Capture One is really good. Rendering wise, it's quite good as well. The weight is about the same with Leica S in hand, ergonomic wise is not as bad as I first hold it... maybe I am slowly getting use to it. The vertical grip is complete bare metal parts, with that blue tint grey paint. Potential to chip like nobody business.

Focus speed is impressive, almost a 135 system fast. And the rendering from the files so far has been great, and the 16bit color is really nice.

would love to see some Shanghai night photos with the GFX100 :)

Tested the GFX100 today. Very impressive IBIS ability. I can get pin sharp image from the 110mm f/2 handheld at 1/40.

The 16bit color is quite nice too. The machine firmware is still buggy though. can't wake up from sleep.

the Shanghai exhibition center + Shangrila shots [on flickr] look amazing :)

Thanks. That was a stitch, the 23mm on a 44x33 sensor is just not wide enough for this cityscape shot.

The perspective on the right look off....

This one is with the 110mm and handheld shot at 1/40. I think I can push to 1/20 with confident.
