I have to agree. The size difference gets even narrower when you factor in the lens adapter and an UWA lens. Granted, weight savings of any amount are very welcome for those of us who do a lot of backpacking, but the camera needs to be up to the task of surviving extreme conditions for that kind of photography as well. Until they make a successor that has real weather sealing, Sony won't have produced a superb camera for landscape photography.

The size is smaller. To me that's an advantage.

But the number one thing for me is image quality, not size.

Understandable, though the image quality will be quite poor indeed if the camera dies from exposure to moisture. My understanding is that it and its lenses completely lack weather sealing, so moisture and dust are going to be its enemies. So it's a reasonable option for people who have a second, sealed camera body or who don't shoot in weather or environments that require one.

agreed!

I'm testing this all first hand to get a better idea of things like durability as you're right, it could be a major pain point.

I've read multiple reviews that say the A7/r have sealing. In fact DigitalRev on youtube poured water on one.

That said so far I can't find anything from Sony that says they are indeed sealed. I've been debating between the A7r and 6D but if there is no sealing I think that might be my deciding factor to get the 6D.

Not sure about this either. The Sony A7R EF lens adapter is airtight, there's nothing getting through there. The only other two points of entry appear to be the two mic ports at the top.

Does it actually have a rubber gasket like L-lenses do?

I too would like to know what the real story is with the weather sealing on the a7r. Early on someone said the internals showed no signs of sealing. Sony says nothing about sealing. And yet the internet has picked up and repeated the idea that it does have sealing on just about every blog and review site now.

I'm using only Canon EF lenses on the A7R, zero sony, zeiss or minolta. So yes, the rubber gaskets are present on my L lenses.

On my 1Dx, 5D3, D800E and 6D, I'm still getting tons of sensor dust and I clean them often, sometimes once a week on my active camera...

That said, doing a search on Sony A7R weathersealing doesn't come up with any search results.

My sense, from having used it now only for the past week, is that if the two mic ports are covered (because they are vertically oriented) I feel comfortable shooting along the coastline with lots of seawater coming into contact with the body, and light rain.

But my impression is that the durability on the SLRs is greater. I do quite a bit of shooting in harsh environmental conditions and I'm not worried about it.

Now something that I've wondered about the A7R that I haven't gotten any clarification is around the sensor design.

Nearly all DSLR sensors have an optical-low pass filter, which is situated just above the sensor. If you scratched the sensor, you're actually scratching the low-pass filter.

The D800E and the A7R don't have one, so I'm wondering if the sensor is completely exposed. In other words, if you're cleaning the sensor you may actually be touching the actual sensor, as opposed to the low-pass filter...

I really don't get why anyone would buy this for size-especially someone who shoots landscapes??? With the lens it still means you don't have something that fits in your pocket, and landscspe is typically tripod so mehhhh

It fits in my coat pocket with the 35mm prime. It also fits in my work bag, glove compartment, wifes purse etc etc

Long story short, I have my a7r on my at all times...including many situations in which I wouldn't bring camera at all. I've already taken numerous shots that I otherwise wouldn't have.

The spec on dpreview claim that it is "Environmentally Sealed", whatever that is.

Technically the D800E still has one...it just has another filter that cancels out the low pass.
If Nikon removed the full low-pass filter, it would cause the focal plane to move; also, the camera still has to reflect infrared light. The D800E still has 3 layers, but two of the layers cancel each other out.

I'm also heading to the Sony camp, after playing around with a NEX-F3 and NEX-FS100.

- Medium-format resolution range

Although this is BS in my book, the 35mm chip is still 35mm, not 645 or 6x6.

Even with almost 40 megapixels it doesn't change the size of the chip.

I'd rather have a real MF back with 6MP, than a 80 megapixel 35mm camera.

I love it how you say this right after you say you're switching to Sony after having used a compact camera. lol.
