On article Sigma 100-400mm F5-6.3 DG OS HSM sample gallery (142 comments in total)

Is it possible Sigma gave you a Canon 100-400 L ver.II painted black? Did you look closely?

Just downloaded one of the 400mm raw files (Cardinal) and I am impressed with the sharpness (centre anyway) at f/6.3. I was concerned after seeing a couple of end user samples...now I am relieved.

SimenO1: Since the equivalence police haven't been around yet, I will just point out that this is _not_ a 20-1200mm lens. Not even close. The aperture numbers f/2,8-5,9 are true, but if DPR calculate an equivalency of the focal length, then the related aperture (focal length divided by aperture diameter) should also be calculated to an equivalence and presented with the equivalent focal length. If not, it will give a false impression of what we get. Wrong combination of numbers.

That said, the camera looks terrific for some.

I don't really get it. In the "olden days" you could say a 50mm lens on a 35mm camera was roughly equivalent to a 135mm or 150mm on a 4x5. The other differences were obvious and not worth the discussion. You knew when you wanted 35mm and when you wanted 4x5.

lwestfall: Good stuff! How about the more compact Laowa 12mm f/2.8 Zero Distortion lens?

I was thinking that myself. I you already have the 16-35mm, the Laowa might just be enough to give you that extra wide and avoid the crossover and weight.

These are terrific images BTW.

proudfather: Fred Miranda has won Featured Thread on his own site 12 times. His pictures are very nice though. I don't believe any cheating is going on. And no one has complained about it. But it seems like a similar conflict of interest, just with much less at stake.

Didn't realize it cost to enter. Completely different!

Good point about Fred Miranda, however it "feels" different to me for some reason. Maybe because there are no prizes, certificates?

Noah Placebo: Alle the images looks so fake.

Why does everybody love fake imagery?

Art is fake reality.

mxx: I did not see "USA" mentioned anywhere, but the article seem USA-centric, so the multitude of DPR members from the rest of the world should just ignore it, I assume.

For instance, the "top publications" you mention certainly are not the top publications for people living in other countries.

It would be interesting to see what the global makeup of DPR readers is. Also their advertisers.

I don't understand much of the talk regarding equivalency. I think most people would assume that when an article talks about a small format lens being equivalent in focal length to a FF setup they are talking about magnification only and it is obvious that everything else would be different.

Does this camera's magnification equal that of a 20-1200mm lens on FF?

techjedi: Can someone explain the advantage of the upside down feature? Couldn't the rail accessory just be mounted to the top of the ball instead? It seems like the ball needs to be locked down tight regardless.

The only thing I see is it has the level built into the base but you could put one somewhere on the camera.

Better battery for the a6500 would be nice. Not that I mind bringing an extra battery or two on a photo outing, they don't take much space. It's when I forget to do that... :-)

a6500 matches in some of those requirements.

It would do a nice job of flattening a coin too. We used to tightrope walk the rails as long as we could and look for used flares...every once in awhile we'd find a new one.

Zoom Zoom Zoom: I only have one question & one only: does ANYONE, I mean ANYONE, actually buy this camera to use it primarily as a still camera? The answer is most likely no. There is 0, zilch, compelling or outstanding reasons for its price to anywhere be justifiable over other still cameras. So, being the case that basically everyone will use this for video, WHAT IS THE POINT TO KEEP MAKING THIS CAMERA'S FORM FACTOR A STILL CAMERA, instead of simply just making it actually what 99.99.99% of people will use it for: A VIDEO CAMERA! Market it as a mini-RED or a mini-VARICAM or something else that is hip and catchy and "cinema-sounding" that works sales-wise! Done! It is truly a mystery to me that Panasonic keeps year on year making this as a still camera when just about no one uses it as as such & later have to turn it upside down, inside-out & do endless gymnastics with adaptors, cages, grips, all sorts of gadgetry & whatever else to remotely turn this more into something like a video camera!!!

Jorginho- If 4/3 IQ is as good as APS-C IQ, then there is no good reason why APS-C IQ shouldn't be as good as FF IQ. So it follows that 4/3 IQ is as good as FF IQ.

I'm kidding but I am impressed with the ISO 1600 from the GH5 as compared to the Sony a6500. The DR unfortunately is not so good.

maxnimo: So if I made a 4K movie with this GH5, would it look much worse than if I used an $80,000 studio camera?

Weren't they making movies and television shows with the Canon 5D a few years ago? I think it comes down more to other things than pure image quality...as PazinBoise says.

The DR links on the Image Quality page don't seem to be working properly for me.

I think the big reason is that the form factor is now accepted as a legitimate video platform.

I can imagine some digital shooters of today thinking "What, only 575,000 images?"
