Looking at the Sony RX 100 next to the new Lumix GM 1 on this site, I think my video camera will soon get a more compact replacement with a bigger sensor.

 

A rebranded G1 could be imo an interesting entry for Leica into the m4/3 market segment, adding some nice Leica lenses to these systems.

M lenses not being so backlisted as they were untill this summer, while a bigger production site in Wetzlar will be started soon, this is not so unlikely.

See this, quoting Leica CEO Alfred Schopf

'He stresses that Leica won't be building on Panasonic's Micro Four Thirds format' (my italics).

 

Entirely consistent with everything Leica has said regarding m4/3rds over the past couple of years........

Any new APS-C system at this moment is crazy... it is a suicide!

 

We will see new E mount FF cameras from Sony for $1000 next year!

Possibly dumb question - but since when has that stopped me!

 

There's no route, via Sony adapters, to get PDAF on the A7R with the new FE lenses. Is there? And if not - are the lenses that you can achieve PDAF via the adapter full frame but with a longer registration distance and therefore in crop mode, or are they full frame?

 

Apologies, I still don't speak Sony, but learning every day.

If it works with the 35 Summilux, I think I'll be happy.

 

Purpose of this camera for me (i.e., why would I use it instead of the M9 - SACRE BLEU!)? Well, it's weather sealed, does video, is compact and rugged, has live view, and takes both M mount and Nikon F mount lenses.

 

This could be a lot of fun.

 

Cheers

I agree John, the feature set seems quite interesting and wide angle use would be a bonus but I've seen couple of dodgy samples so not holding breath. 35 Summilux, I would think would be OK. 36MP with the Noctilux feels exciting for me though and it's everything I was looking for in the M. The cynic in me thinks it would be wise for Sony to cripple Leica lenses enough so you then buy one of their Zeiss lenses. I suppose we will see.

 

Wether it is durable enough for heavy use and wether it will tether reliably etc etc etc are all contributing factors I need to wait out and see.

 

Not sure how I feel about EVF only either. I have the same feelings going to those cheap and nasty department stores with no windows and banks of flouros above for some reason!

Hi Paul,

 

Welcome, please join the club.

At the moment my A7R is scheduled to be shipped December 2, 2013.

Unfortunately I don't have the 75 Summilux. :eek:

So, the 75 Summicron will have to do.:D

 

Amazing! A camera that is announced AND comes out in the space of a couple months! I look forward to hearing your thoughts on it!

 

That 75 Summicron is a very outstanding lens. I think all used market prices on these items is going to rocket.

John,

 

That sounds a lot like the M240 (except for the price)

 

Regards,

Mark ;):rolleyes:

 

It does.

 

And the 36MP, outstanding high iso, AF if you want it, NFC, Wifi, Eye Focus, Dedicated TTL, flash compensation, high speed sync, focus confirmation with manual lenses, accurate framing, A USB port without the need for a stupid expensive grip, Decent movie, HDMI out, smaller size and weight.

 

But apart from that very similar.

I can't even imagine why they think this would be viable right now. Perhaps only because they are heavily invested in it and trying to save face. Either that or they have entirely lost touch and aren't even aware of the A7r which seems entirely plausible these days.

Since I have no experience with manual lens focusing via EVF, I'd like to know how this works in practice:

 

* Focus wide-open, then stop down (possibly with the risk of introducing focus shift); or

* Stop down, then focus (with potential focus error due to depth of field and/or insufficient light)

 

How do those of you with an EVF on your M, NEX, or whatever do this?

I've scoured some a7r pages over interwebs and have to say I'm very curious to try this camera out. I think it is going to work very well with something like the Noctilux and 75 Summilux and I may just buy one for that alone and leave The M9 for the 21mm and 35mm Summilux's.

 

I'm excited to try it out.

 

Your idea is not a bad one because also you can be changing lenses less and therefore hopefully keep your sensors cleaner.

 

And don't forget that with a Techart adapter the AF feature works on Zeiss Contax G lenses which have a very good reputation for sharpness.

Thanks. Great questions. You can do both until about f/5.6 or f/8.

The EVF just cranks up the gain.

Beyond that, depending on lens, some can get very dark.

Others stay light all the way.

 

I typically focus with magnification wide open or one stop down.

Most of the lenses I have are performing very well for those f-stops.

When one switches back to full view focus peaking shows areas of high micro contrast.

That's interpreted as being in focus.

 

The latest EVFs, like VF-4, perform a lot better than the previous generation though.

So I expect further steady improvement in the future.

But for focusing and framing purposes I find the image qualities of EVFs already good enough.

To me the haptics, for lack of a better word, of a camera is important.

It has to feel right, so button and switches have to be conveniently placed and be configurable.

 

In this context the Olympus E-M1 is exemplary for the way I operate a camera.

It can be configured in such a way that there is hardly any need to go into the menus.

There are also two levels of menus, one complete one, and one shorter one for most important functions.

 

Of course, menu layouts are quite different, say between Olympus and Sony.

I deal with that by spending some effort memorizing them as much as I can.

Having done so for a few cameras helps considerably getting acquainted more quickly with a new model. :D

True. Also, the Olympus cameras with IBIS seem to have a very effective dust removal system.

In over a year of use I have not felt the need for a wet cleaning yet.

Others have a similar experience.

Because of the 5-axis In-Body-Image-Stabilization IBIS I wouldn't touch that sensor with a wet swab.

Using a blower is fine.

 

Of course, the new A7/R don't have IBIS. But future models certainly would benefit from that.

Karl,

 

That is true about the A7/A7r not having IBIS but future models will. However, I would expect those models with IBIS will need to be substantially larger due to the size of the IBIS. Case and point look at the size of the IBIS for the A99.

At the price of body, and if it works out as hoped, I would see myself having more than one body. Who knows, maybe even one for each lens. That would be great for many reasons, minimal dust being one of them.

 

I'm not imagining a 21mm Summilux to work so well so I can leave the M9 for that. Given that my two mostly used lenses are Noctilux and 35 Summilux it could be a perfect solution.

Very interesting - it's French though! Even the pictures! :D

 

Test Sony A7R - Focus Num Caractéristiques

Test Sony A7R - Focus Num Gestion du bruit électronique

Test Sony A7R - Focus Num Exemples de photos

 

So I processed their ISO 12,800 image sony-a7r-exemple17.ARW in CS6 and Nik.

The image cleans up very nicely and has excellent IQ.

I will have no problem using the A7R with ISO 12,800 or even higher ISO values.

As expected! Terrific! ;)
