D1N0: F4 is more compact and lighter than F2.8. On Full frame it is adequate on APS-c a bit slow. Price point is a bit high though for a less well known third party manufacturer. I wonder

Depth of field will be the same, angle of view will be different (making you have to use a different focal length or distance to subject) :P

fdfgdfgdgf: In a few months all upcoming models will record 4K internally.

Just a few months? Sweet. Too bad the new 7S missed out by just a few months :(

In reply to:

InTheMist: Can someone explain to me what it is?

Ever seen a set of a TV news broadcast? You'll see cameras with big viewfinders on wheeled tripods. They'll look kind of similar. This like a mini/cheap version of that. big screen so that you get a good view of the framing without having to have your face right up to the screen.

It's a pretty niche market I would think, though, at this price, they could score big especially as broadcasters are trying to push to 4k content, this could be a cheap way to get their feet wet. Not to mention all the enthusiast media peeps who are building out small studios.

photophile: "3 separate built in LCD monitors for camera settings and metadata entry. Large 10 inch screen folds out for full resolution HD monitoring with wide viewing angle and high brightness."

Battery life ?

And more people to shake the camera while filming :( I wish they rather had a wireless API so that any mobile device/tablet could get the pertinent data and change settings without being tethered.

In reply to:

aramgrg: With such costs, why haven't they bought(or at least rented) D800E, I think the difference would have been visible!

minus overlap, I wonder how many GP the final image is, probably closer to 8gigapixel.

Neat shot, I like that it includes the tower, very good! I kind of wish they used a 180mm or longer though :)

In reply to:

ragmanjin: They've said in a bunch of interviews that their next MF should be mirrorless, I'm hoping that's what they're going to do. THAT would scare the pants off every other ff/mf manufacturer out there...medium format with the same quality as the latest-generation Phase/Hassy offerings at a size comparable to the D4 and D1X or even 5DIII and D800 — and a price less than the new 35mm "Hasselblad" single-lens translucent, nonetheless.

....
Sorry, just drooled on the keyboard a little.
On the other hand, if they pull the same "mirrorless" thing with the 645DII as they did with the K-01 (same mount and therefore size as before) I think they might miss a big opportunity. If Leica can break into the market so late with a limited line of lenses, there's no reason they shouldn't be able to change the mount to a 35mm-typical flange distance with adapters to provide compatibility to those with legacy glass.

Just my two cents.

Judging by pentax's only other mirrorless model, I'm not too keen on a mirrorless MF body... it'd be the same size as the mirror one and look really goofy

In reply to:

photo perzon: I wanna see it with a 14mm lens on it.

Looks like a simulation, and it doesn't look right. The 14mm should be much wider "looking" on the GM1, look at the lens' mount, on the GX1, the 14mm is sticking out over the sides of the mount, but for some reason the GM1 it's flush, should be the other way around IMO.

In reply to:

f_stops: Lenses like these are a good reminder the DLSR isn't on its death bed, despite the giddiness and excitement over the Sony A7 duo. Canon and Nikon will have a lock on the pro-level sports/bird/telephoto market for some time to come.

And congratulations to Sigma for getting it together with some great top-quality lenses. Hope they can continue to deliver with decent quality control.

Not that I disagree that the sports market is going to be dslr for a while, but Sigma makes lens' for many makers, what's stopping them from bringing their lens' to FF E-Mount? If FF E-Mount or whatever mirrorless format takes off, lens' like these will shine also.

Given the constant aperture zoom lens', it's very compact (the lens barrel doesn't stick out like a sore thumb), color me impressed. Good job Oly!

Dimit: To the DPR editors:
First thing you were about to do writing down your first impressions would be to search around the diameter dimensions of all mft pancake and small lens as 12,14,17,45 mm,etc.
It took me 12 minutes to verify that NONE fits the othewise very interesting camera WITHOUT PROTRUDING OR BEING EQUAL TO THE HIGHT OF GM1 !!!
The camera can't ''sit'' on a surface with any lens otherthan 12-32 !
The camera should be 0.5 to 2.2 cm higher!!!
Glad to have your feedback,
Regards..

indeed I would have liked to see some images of smaller primes mounted to the camera.

On a side note, I always wondered why lens' had to be fully round at the top and bottom anyways, the lens' elements are usually very small, if they really wanted to make a system that could be smaller and avoid these problems, they should have made smaller lens' with flat bottoms!

In reply to:

DDWD10: I'm a little concerned about the 1/500s mechanical shutter limit. Using the electronic shutter at higher speeds, would one expect CMOS rolling shutter artifacts or not?

The downside of leaf shutters is that they often don't have quick shutter speeds where you need them (wide open), the maximum shutter speed is often at smaller apertures.

Though there are many positives of leaf shutters, and would have loved it to be in the m43 spec. near silent being my favorite, but the ability to have less mechanicals in the body reduces failure points and allows for smaller designs, it might have even allowed for internally retracting lens'.

In reply to:

WhyNot: Another interesting camera.. What surprises me most is the lack of the viewfinder option the LX7 has. It may have attracted a few of us that have that viewfinder and maybe sold a few at the cost of a couple mm in height.. As to pocketable I think that will be dependent on the pocket; and, being an interchangeable lens camera we'll probably have the 20 or 25mm lens on it and then how pocketable will it be?

Seems space is at a premium with it's compact size. Even though there is "space" on the top, a hot shoe protrudes downwards into the body, and must be strong enough to support the use of large hot shoe flashes, so isn't just something you let the plastic body hold in place. The accessory port its self pushes the depth even greater, probably well into where the screen is, making a smaller screen necessary.

In reply to:

FrankS009: The first impressions review says there is only one lens that the camera will not tip over with. This seems knit picking, and in fact there is also the 14mm pancake and perhaps the 20mm pancake. How many DSLR have unbalanced lenses?

Interchangable lens cameras are inherently better buys than fixed lens cameras because while all cameras are basically obsolete when they hit the market, the lenses offer added value down the road. This lens also seems to be an interesting one.

F.

I think the reviewer is refering to the fact that the lens' diameter of all other lens' is wider than the GM1's height. The lens will stick out below the body, and make it tip over.

I'm surprised how much tippage would happen with the primes you mention, the 20mm and 14mm. I'd have loved to see an example in the preview. Maybe even the new 14-32 next to a 14mm shown from the back too...

On Zeiss announces 'no compromise' Otus 55mm F1.4 article (507 comments in total)
In reply to:

Joseph S Wisniewski: You would think that a company with Zeiss's history would actually have a sense of history.

Back in the early days of 35mm SLRs, all the camera makers tried their hands at 55-58mm f1.4 lenses. It's a focal length that lends itself to better optical design at f1.4 than a "true" 43mm normal. Photographers around the world rejected them, and pushed for a less "flat" normal, something closer to 43mm.

The end result was a "meet you half way" compromise, the 50mm that ruled for decades.

I think Zeiss is about to relearn history, as compromising the focal length to get "uncompromised" optical quality isn't going to work any better now than it did 50 years ago.

I think the market is different these days. Not only being bigger, but there is a market out there for non-compromise optics at big bucks. It's a niche market, but it offers some great bragging rights, and is perfect for a company like zeiss.

It's not going to burn up the sales charts, but at that price, I don't think it's suppose to. If the tests are amazing, then it's done it's job.

On Did Sigma design the Olympus M.Zuiko 75mm F1.8? article (200 comments in total)
In reply to:

pdelux: Still not convinced..
If sigma could make a lens this good for the m43 format, why are their other Sigma branded m43 lenses pretty average?

It would be a big investment for Sigma to make a sigma branded 75mm f/1.8, however selling the use of it's patent to Olympus, and having Olympus produce it, and make it work (pay for everything else), is great.

Besides, Olympus has great lens' factories for high precision parts like this that were probably just sitting idle.

If it "was" a sigma lens' made fully by sigma, it might have been a different lens in a lot of ways.

In reply to:

mmitch: WHY? None of these incredible shots benefit from color enhancement. They all look fake to me.

Maybe your color blind? just kidding ;)

To me they benefit greatly, but I'm probably of a different generation than you. And they don't look as fake as when they used to colorize film prints. I'd actually say they're impressively realistic for the most part.
