That's really heavy, man.

The 750D and 760D are clearly better than the 700D. Other than that I can't tell the difference with other comparable cameras.

All of the latest cameras are starting to look so similar in these studio shots that I really can’t tell them apart.

mpgxsvcd: Just curious. But why F8.0 and ISO 800 with an L lens and not F4.0 and ISO 200? Would depth of field be an issue with F4.0 and this A-PSC camera? Does this lens have more detail at F8.0? I would have thought that the L-lenses would be better closer to wide open than stopped down. Isn’t that the point of their higher cost?

Cool. Thank you for the reply. That makes total sense. Great job on the pictures by the way. I thought this set was excellent for judging the camera’s abilities in a sorts of situations.

Looks like a good set of images. I got what I wanted to know out of that set.

Who was the photographer for these images. I thought there were very good. There really was a wide variety of exposures, content, ISOs, and focal lengths. That is very helpful.

mpgxsvcd: I am not seeing a lot to dislike about this camera. They would sell a lot more of these if they advertised them more and also sold them in stores like Best Buy right from day one. As it stands right now Canon will sell many times as many T6s/T6i cameras as Panasonic will sell G7 cameras.

That is also despite the fact that the Canon cameras had a significant defect in a large portion of their initial shipments(Which they addresses quickly), the T6s only does 5 FPS vs. the 7 FPS for the G7, The G7 is cheaper, and the G7 does 4K @ 30 FPS video vs just 1080p @ 30 FPS for the Canon cameras.

Panasonic’s issue is not that they don’t make great cameras. There issue is that not enough people even know they make cameras.

Yes. The knock on mirrorless is that it does not perform well in the U.S.(North America really) and Europe. North America is a significant market that M4/3s would love to really break into. Canon absolutely rules it at the moment in this class of camera.

In reply to:

Mirfak: 20 comments so far and all positive. How is this even possible? :-) I guess that all of the naysayers are still asleep. Wake up boys!

I am always accused of being a Canon hater so let me give it a try with Panasonic this time.

1. The battery life of the BLC12PP has been dismal in the past(FZ1000, GH2…. Etc).

2. The G7 really isn’t that much smaller than the GH4 and it is considerably bigger than the Canon M3.

This is actually harder than I thought it would be. I really can’t think of any more drawbacks that would prevent me from buying or recommending this camera.

jnxr: Has flash, 4k, EVF, large sensor, small size, good lens options, and much more at a very sensible price point.

Isn't this device more of a convergence device compared to the Canon XC10?

In reply to:

mapgraphs: Richard, Rishi,

When you make statements like "most cameras have low upstream read noise" it would be helpful if you cited your source for the statement. And the same goes for every other statement of implied fact. Your sources should be a readily available so that anyone can easily access them.

Otherwise this is just an editorializing opinion piece. If it is intended as an opinion piece, that's fine, but that should be set out at the beginning.

Upstream read noise is a variable value, which can be affected by heat and the software used to interpolate sensor pixels:

"Interpolation works by using known data to estimate values at unknown points."[1]

"Image interpolation works in two directions, and tries to achieve a best approximation of a pixel's color and intensity based on the values at surrounding pixels." [ibid.]

Some statements may be an opinion. However, those opinions are based on years of testing and examining every single consumer camera model that is made by some of the most knowledgeable people in the business. I don’t accept every opinion Dpreview says as fact. However, I definitely consider it to be the leading hypothesis right out of the gate.

In reply to:

JRFlorendo: Just in case Canon gets slapped with a class action lawsuit with regards to selling defective product, Canon can always say "you knew our sensors sucked, why did you still buy it", sooo sad indeed!

I wish Dpreview would bring back the "Dislike" button just for this comment. I know I usually hate on Canon but I don't think this comment is called for at all.

They handled the T6i/T6s issue about as well as they could and while I think their sensors are inferior to the Sony sensors used in other cameras I don't think that their sensors are that bad. You can buy a better camera for less money than most Canon cameras. However, if you choose to buy a Canon camera for other reasons you can still make great pictures and videos.

In Astrophotography we use dark frames(And other stacking techniques) to significantly reduce the read noise and very long exposures with relatively gigantic apertures(10+ inches) to reduce the shot noise. Does this theoretically eliminate the differences between cameras with the same size sensors?

Also will a full frame camera still have their inherit size advantages over smaller sensor cameras if you are fully utilizing the stacking techniques?

Great articles by the way. You have convinced me of your argument when 6 months ago I simply didn’t believe it because I didn’t realize how big a factor shot noise was in short exposure photography.

In reply to:

mpgxsvcd: The dust proof and splash proof is not my big worry. My big worry is how to protect that front element. You can’t put a standard lens cap on this lens, right? I really want it but I can’t figure out how to properly transport it. I don’t want to carry an extra bag just for the lens.

One of the pictures Dpreview posted shows it with a nifty lens cap/enclosure. Therefore, you might not have to be extra careful with it. I just hope they don’t charge extra for the lens cap like they do for lens hoods with some lenses.

In reply to:

mpgxsvcd: I was worried about how to cover the lens. However, picture 10 shows the lens cap/enclosure very well. That probably will be my next lens purchase.

Could you demonstrate how the lens cap works. It wasn't clear from picture 10 exactly where the lens cap attaches to.
