Hi, I have the A7, because it offers better UWA/WA support for Leica M mount lenses (some needing the SONY lens correction app, too).

 

Thanks, I thought that from the lenses you were liking. Sounds like a decent M backup if you can use M lenses from 12-135 AND can use Sony FE AF lenses.

I don't think we can talk of lens in isolation. One can't use zeiss 55/1.8 on M therefore only way to use it will be to accept the +/- of A7/r system.

 

Anyway, my original question was whether Leica has any 50mm lens in its arsenal with corner to corner sharpness at wide aperture.

 

(disclaimer: I am still on M9)

 

 

 

I'll take it as a given that you shoot perfectly flat objects square on with the lens and the lens wide open often enough where having no field curvature is a concern. Maybe the new 50mm 'cron is worth a look (I've no experience with the lens not have I done any research on it).

 

 

 

That corner sharpness is restricted/compromised/fixed in the camera firmware, with the digital sensors, even the well adjusted, for their lenses, Leica ones. Unless the new Summicron was designed specifically for digital they were all designed for film and yes there is a difference, all to do with the sensor cells, their depth and micro lens (if any) angles. Any digital lens test is examining the combination of lens and sensor. hence the excellent lenses that are performing poorly on the Sony series, they are not bad lenses they are not poor, smearing the corners, the combination is doing that.The Sony glass is "matched" to the sensor design, optimised if you like, much as with the tolerances involved in "perfection" the Hasselblad H digital series (3DII onwards) are matched back to body.

 

 

It'd be strange if the new Summicron was not designed with digital image capture as its primary usage.

 

I think we agree on the rest.

Hi, I see the A7 as a complementary camera (body) to my Leica M9, the NEXen and the Olympus Pens.

 

I do not have SONY lenses (at present), as I have 4 35mm with M mount, and 3 50s.

 

The SONY 1,8/55 must be very good, from what I have read and seen.

 

However, doing mostly landscape and architecture travel photography,

55mm is a little long for my taste, and I do not like its size with lens hood.

(I like the sliding hood of my Leica Summicron 2/50 better.)

 

So, I must (and can) live without AF.

 

But one never knows ... There are rainy days, and you are trying to make

yourself a little present ...;)

Indeed. The redesign is not major, close attention to exit pupil and impact angles of light at the edges, and allowance for the greater reflected light coming back at the rear of the lens from the sensor reflections the rest is down to glass types and shapes. I suspect that modern computerised machinery has allowed more extreme shapes and precision certainly the recent advances are not restricted to one star designer or manufacturer. Zeiss, Sigma, Sony Leica (in no order) have all shown new glass which has pushed what we expect in performance. (and just to rake over old ground, in small size lenses as well :D ) Some at affordable price points

I agree. I got the M240 last summer, and then the a7 and a7R after a few months. The M240 essentially replaced my M9. I think if I had it all to do over again, I'd skip the M240, keep using the M9 for lenses 35mm and shorter, and the two Sonys for 50mm and up. I'd gain a backup camera, and I'd save some money, although that's debatable if selling the M9 is factored in.

 

I'd get better live view than the M240, and slightly better low light performance, although I'd have to settle for worse low light performance for short lenses with the M9. I'd have the integrated EVF, and wouldn't have to keep taking off the M240 EVF when I want to make flash pictures (yeah, I could have bought the grip). I'd have the articulating LCD on the Sonys, which I thought was no big deal but now I love (you can kind of get the same thing on the M240 by swiveling the EVF). I'd use the Zony 55 f/1.8, and for now the rest Leica or other third-party glass while I waited to see what was going to happen with the Zony FE lenses -- I don't want to jump into a new lens line with bath feet without a really good reason.

 

Shutter shock? Certainly a concern. That's where the a7 comes in. It's useful when M240 resolution is enough and you're worried about the a7R shutter. BTW, in spite of the a7's AA filter, I've found it the equal of the M240 for horizontal features, and not bad for vertical ones. And I'd have the a7R for places where high-res really counts.

 

Cost? Two Sonys are substantially cheaper than one Leica.

 

Weight? The M240, battery, strap, EVF, 50 'lux, and RRS plate weigh 46.2 ounces. The a7, a7R, 2 batteries, straps, 55mm FE, and RRS plate weigh 48.2 ounces. But there's that M9 to weigh you down when you travel, so that muddies the water. And if you go with the M240 for everything, don't you still need a backup body for travel?

 

It's not so simple, is it? But if you've got an M9 and haven't taken the leap to the M240, it's at least worth considering.

Hi, I only have the A7 and the M9.

 

I did not buy the M240, because I am unhappy with the manufacturing quality of my M9 body. (Less diplomatically put, I find it shitty.)

 

So, not knowing whether I would get real value for money and proper UWA/WA support, and not liking the bolt-on EVF, I gave it a miss.

 

I do not have any SONY lenses (which are said to be very good), because I am happy

with the performance of my 21 M mount lenses.

 

Cost is not my (main) concern ... Photography is my hobby, which I practice with flexibly deployed rationality ...

Now I have heard BS, but this takes the cake. You experience GAS just like the rest of us who rationally deploy flexibility.

Sorry for the wording. --- Not everybody understands irony, or self-irony ...

Ok, I'll bite.

 

What are the 21 M mount lenses?

See message 4340... he means he has 21 lenses he can mount on an M...

Hi, I have M mount lenses from Leica/Leitz, Voigtländer and ZEISS.

 

E.g. I have 3 21mm lenses, 4 35s, 3 50s, 2 90s and 2 135s, 21 in total.

 

(And there are Leitz/Leica R, Nikon, Minolta and others, over 40 ...)

Quite witty really. Your FDR seems to describe nicely any expensive non-essential purchase.

Hi, yesterday I took my A7 and the Leica 3,8/24 APSH for a stroll to do some field studies.

 

So, here is a picture of a field (ISO200, f8, AWB auto, JPEG ooc):

Doing landscape photography, I had a close look at the right middle side (f3,8; f4; f5,6; f8).

 

F8 I can live with.

Hi, inside the church in Eberheim/Germany (same setup as above, f8).

 

The crop shows strange effects I have not seen with this lens on my M9, or NEX-6.

 

Nothing to get excited about, but it can happen ...

Hr.Polygamer,

 

When you aim your camera toward the strong point light source, the polygons in the image are exactly the shape of the aperture opening. The f/16 aperture setting allows you to obtain a perfect round shape, while large opening such as f/4 let you get a clear polygon with eight segments (the same number of Lieca M lens aperture blade). Please see the attachment.

 

When the oblique beam of the strong point light source comes into the lens, i could be reflected by the walls of adapter, lens inner barrel, or even the surface of certain lens element and make happen the "flare" on the sensor to create the polygons shown in your image.

 

For environment with radiant light, try to set creative style as "Clear" to see improvement if any.

 

Best Regards,

 

Thomas Chen
