Sorry. I thought the question " ... and if I can get IQ like that with my 21mm lux I am a buyer"

 

referred to an M Summilux ...

 

(because I cannot see any problems whatsoever with an R Summilux 1,4/50 on the A7R).

I've tried searching this thread to get an overall opinion but I can't find examples (easily in 225 pages).

 

My question is the prevailing evidence about whether or not either the Summicron 35 or Summarit 35 work well on the A7.

 

I have a FE 35/2.8 but I am not happy with its character. I also have a C-40 Summicron which works well (very sharp, no smearing or colour shift). However, even though it is only a 5mm difference I do find it a tad restricting.

 

Can anyone post samples of the A7 with either of the two Leica lenses - or point me at examples?

 

Many thanks

Hi, I have an A7, Leica Summarit 2,5/35 and the Summicron 2/35 V4.

 

Both work on the A7 with the SONY typical weaknesses, meaning corner and

edge performance gets better when closing the aperture.

 

I have posted examples in this thread:

but I shall post 2 examples here, too.

So, here we go, the 35 Summicron at f8, JPEG ooc, no PP:

And the 35 Summarit at f8, JPEG, reducing brightness, enhancing shadows:

So, you might ask, why do I have both. --- Why not? I have 4 35mm lenses with M mount ...:D

 

Seriously, I bought the Summarit because I expected better performance with a more

recent Leica Lens on the A7, which I did not experience, however.

 

The A7 is capricious and in some cases seems to work better with the not most recent lenses, cf. 21mm and 24mm.

 

If I could have only one, I would prefer the Summicron 35 V4 over my other 35s.

(It is also more compact with the lens shade mounted.)

 

But maybe, I am biased. I have used the Summicron since 1988, when I bought my

Leica M6 ...

Hi, the market in Mainz (where I do my shopping on a Saturday). SONY A7, Leica Summicron 2/35 V4:

For my sins I started one of the several threads that were merged into this ship of state that has been sailing the waters of the Leica forum for well over six months. I cannot claim to have read every post but there's a wealth of information to be gleaned. In the meantime I have been plodding away with a loan A7r and have used it mainly with three lenses, 50mm Summicron, Summilux and 75mm Apo Summicron (one of my favourites).

 

I've had good results as you can see from my picture of this Greek pussycat (or psipsini as they say) taken with the humble nifty-fifty Summicron. Not a whisker out of place and I think this is typical of the good results to be had from a careful marrying of Sony and Leica (I have had a few very minor issues with 35mm and wider, however). While on balance I do prefer to use my M or Monochrom (focus is so much easier with a rangefinder, I think) I really can see little objection to the A7 as a second body or, even, a first body for anyone with a stock of modern Leica glass. Apart from that egregious shutter noise, it's an excellent little camera.

You can also consider of trying the R lenses: 35 Summicron and 35 Elmarit. They are very cheap (for Leica standard) on the used market, and in case you don't like them you can resell them easily. I use these lenses on the Ricoh GXR with great satisfaction. They work very well even on my Olympus E-M5, whose sensor is typically rather problematic with older wide angle lenses.

Hey all.. I'm slowly making my way through this thread, but thought I'd ask and get some initial responses.

 

I'm pretty much sold on ditching my Fuji setup and using the lenses I have for my M-E with either the a7 or a7r. FWIW, they are all 35-90mm. I plan on using a Nikon 24mm lens for landscape work, so I'm not worried about the WA/UWA corner/color issues.

 

I really want to go with the A7r but I've heard some worrisome things about shutter vibration (initial research seems to indicate this is more of a hand-held tele-zoom issue?). I would love the larger image resolution and lack of AA filter, but I'm not 100% decided yet.

 

The primary use for the a7® will be as a second body (if I have the 35 on my M-E, I'll have the 50 or 90 on my a7®), and for landscapes with the Nikon lens. It will also fill in for low-light work as the M-E isn't so great above ISO 800.

 

My lens lineup will look like this.

 

Nikon 24 2.8

CV 35 1.2 II

Zeiss 2/50 ZM

Heliar 75 2.5

Summicron-M 90 (or Elmarit 90 2.8, still testing these out).

Either the 28-70 Sony kit lens or the 24-70 Zeiss Sony lens for times that I need AF.

 

Give those lenses and my primary use as a 2nd body / landscape camera, would anyone disagree that the a7r is the way to go? If you feel the a7 might be better suited, I'd be interested in hearing the reasons you feel that way.

 

Thanks, and I look forward to reading the rest of this mega-thread! :)

I guess that all lenses of your lineup will produce results where the A7R shows more limits of these lenses than vice versa.

 

The shutter vibration issue should be quite negligible for these lenses. The A7 is a bit better compatible to M legacy glass but has some issues with sensor reflections in combination with particular lenses. The main question is if you want to have the crop reserve of a 36 MP sensor.

Seems to be unsharp? Lo res perhaps. But no doubt a friendly yet hungry animal:-)

Possibly...

The only relevant lens he's tried is the 15mm Heliar, lets wait and see how it does with other m lenses, otherwise its pretty irrelevant here. ;-)

Well, yes and no. He's impressed about the things he publishes. As he's explained many times, he doesn't like negative things and thus only publishes reviews for stuff he likes. If he doesn't like it, the review is never published.

Owning both the A7 and A7r I can find no practical difference...... I belive it would be the same

with the A7s..... enough is too much. The A7 is a wonderful camera for a lot less $!

Great with Leica glass.

 

The A7 is great with some Leica glass but not all. You have to be selective at focal lengths wider than 50mm. As someone who owns the 15mm Voigtlander I must say it's performance based on the images in Steve Huff's review represents a significant practical difference from either the A7 or A7r. If this remains true for my 25mm ZM Biogon, then the biggest obstacle that discouraged me from buying up to now has been removed. When you take into account the 'silent mode' shutter release improvement on the A7s, I think it will be all the reason many

so far hesitant M mount lens owners will need to take the plunge.
