I may take 400 still images and of these maybe 1 of these becomes a print. The rest still needed to be captured and transferred and stored and backed up to a NAS. With 8K video it would be more like 16,000 to 1 in terms of images that become a print. This is an excellent example of where more is less.

And the problem it creates in having more images to review is not trivial at a time when there still does not exist a viable image search engine and instead one has to rely on meta tagging and relatively crude DAM applications or even worse, the library structure of Lightroom or CaptureOne.

On article Nikon D7500 vs Canon EOS 80D (264 comments in total)

When determining how high an ISO setting is usable I do a test with tungsten lighting and a dark skinned subject and preferably wearing a dark blue or red top as this is when noise is going to be most evident. With this test with the D810 and the D7200 I found that ISO 6400 was safe to use. Chroma noise was well controlled.

The problem with low light shooting is seldom the noise at the ISO setting needed for the exposure but rather the ability of the camera to lock focus quickly. That is where the additional cross type autofocus sensors of the D500 make a tremendous difference.

On article Applying color theory to landscape photography (87 comments in total)

One does not go out and "make pictures" unless you are talking about snapshots for some social media posting. Ansel Adams stated many years ago "The negative is comparable to the composer's score and the print to its performance. Each performance differs in subtle ways" but people still do not get it. The negative has been replaced by a RAW image file but that is still the starting point in creating the final "picture".

If someone cannot be bothered and prefers to capture to JPG and go right to the Web that is certainly OK but if someone really want to capture the essence of a place, as Bierstadt did with his paintings, then an understanding of the technical aspects will elevate the results of ones efforts.

More photographers than one might realize had classical training in other media before going into photography and with Cartier-Bresson there was a return later in life when he quit taking photographs altogether.

When the Leica cameras were the only game in town in the 40's, 50, and 60's, and they only provided a viewfinder usable for 50mm and shorter focal length lenses and offered very few focal lengths, I could understand photographers shooting nearly 100% with a 50mm lens on their 35mm film cameras. It makes no sense at all to be doing this now with all the great zoom lenses, like the Olympus 12-40mm f/2.8 (equivalent to 24-80mm f/2.8 on full frame DSLR). This lens is 2.75 x 3.3 inches in size and weighs 13.5 ounces. Added to the E-M1 Mark II camera with its battery and the total weight is only 2.1 pounds, or the weight of my D810 body alone.

Posts by owners of DSLR cameras show remarkable ignorance and an inability to embrace new advances in technology. It reminds me of the Luddites who said 35mm was a waste of time as only a MF camera could produce quality images.

What is different with the MFT is the ability to shoot hand held with equivalent of a 600mm f/4 lens (using the Olympus 300mm f/4 IS lens) at 1/8s and get perfectly sharp images. Also no need to calibrate lenses to compensate with differences between the focus point with and without the mirror in position over the sensor.

A full MFT kit with two cameras and lenses with focal lengths from a 35mm or full frame equivalent of 14mm to 600mm at f/2.8 with the zooms and f/4 for the super telephoto, and two flash units, all fit in a 18 liter backpack and weighs about the same as my 600mm f/4 lens in its dedicated LoewPro bag with shoulder straps.

DSLR owners agonize over which lenses to take on a trip and this problem does not arise for the MFT system owner.

On photo Denali in the Landscapes with a "Wide Open aperture" challenge (11 comments in total)

This is the kind of scene where it would have been much better to shoot 3 frames at 70mm focal length and stitch them together. Going wider with the 24-70 would have reduced the relative size of the mountains in the background and so compromised the image even more.

calson: As with so many other reviews the individual ignores completely the advantages in size, cost, and performance of the fast pro lenses available for this camera. It is very different than the situation with Canon or Nikon APS-C camera where owners have to use full frame lenses or mediocre wide angle zooms that are also slow. When it comes to a MFT camera and lens kit the MFT kit is going to be half the weight and half the bulk of the APS-C or full frame equivalent and half the cost. I have the Olympus 300mm f/4 OS lens and it is easily the equal of the Nikon 600mm f/4 VR lens that I also own and use and the Olympus lens was a third the cost and weighs 5 lbs. less and it small enough to get on a plane. With my full frame lenses a 500mm is the largest I can take in my carry on backpack.
Most performance issues mentioned are the type that can be corrected with firmware updates which will occur as with the E-M1 camera after its introduction.

Hey below averagejoe576 - who the hell are you badmouthing as a troll. I have thousands of posts on DPreview and own both the E-M1 and E-M5 Mark II cameras and have a E- M1 Mark II arriving today at my house.

I also have pro level APS-C and full frame cameras from Nikon and each has its place. There is no one camera that does it all or that is going to be the "best" in any given situation and it is crazy to talk about a camera without discussing the availability of lenses and flash and third party equipment to fill the gaps from the manufacturer. In terms of lenses and flash Olympus is far superior to Fuji. It is only for a dedicated video camera where there are definite advantages to using Sony cameras and the available cine lenses.

On photo Street Food in the Your City - Local Street Vendor challenge (9 comments in total)

The composition with the man in the left side of the frame and the outstretched arm going to the highlighted corn works very well. What detracts from the picture is the busy background that competes with the viewer's eyes.

This is the kind of scene that needs to be worked with different angles and heights and apertures and focal lengths and shifting to change the background. It also shows why a 35mm focal length is a bad choice for street photography with its excessive depth of field and limitations for excluding detracting/distracting elements.

A rodeo is a very easy environment for a camera's autofocus system. Plenty of light and hard edges on the subjects. Piece of cake compared to photographing the first dances at a wedding reception when the lights are low or the location is outdoors or otherwise dimly lit.

I have to wonder if the PR flacks set up these easy tests so their cameras will perform well in place of a meaningful situation that truly tests the autofocus system under difficult conditions.

No doubt the flagship Canon camera with its autofocus system designed for sports shooters is excellent but a rodeo "test" tells me nothing.

On article D500 owner formally accuses Nikon of false advertising (473 comments in total)

There have been public standards for WiFi and Bluetooth for many years and these have been adhered to by device manufactures as the whole point has been interoperability between different manufacturers products. Nikon's product managers evidently do not understand this.

To get Bluetooth connectivity between the D500 and a GPS Bluetooth receiver I had to buy another Aokatech adapter so no different than any of my other Nikon cameras. I get Wifi and Bluetooth I cannot use and no GPS and no Commander flash. Nikon has become like Microsoft where it takes three tries to get it right.

On article Readers' Showcase: Giulio Magnifico (78 comments in total)

Hate when people produce distorted images with wide angle lenses and think they are being artistic when nothing could be further from the truth. No idea how this gimmicky approach of using a wide angle lens to photograph started but it should challenged and let people decide if a photo with a chosen subject and lighting setup looks better when a 35mm lens is used or when a 105mm lens is used. Doubt many people would pick the clownish image taken with the 35mm lens.

Backfocus in my own experience with Nikon DSLR cameras has been always the result of the camera's autofocus system selecting something behind the subject that provides greater contrast with a harder edge that is aligned so the single axis autofocus sensors can use them to compute when the lens is properly focused. The end result is perfect focus on something behind the primary subject and the new system while maybe easier to use will do nothing to address the key backfocus problems of the past.

On article X-Factor: Canon's EOS-1D X Mark II examined in-depth (615 comments in total)

If someone wants to shoot 4K video they get a card slot that takes the standard Canon Cfast memory card. If a pro shoots stills only then they lose a card slot.

As with Nikon I wish the camera manufacturers would work on making smaller and lighter cameras for those who don't use tripods and hand hold the camera for hours at a time.

Instead we get higher fps that the majority of photographers will seldom or never need. It is like the auto industry that gives us faster and larger gas guzzlers with more horsepower for the buyers that are deluded by the marketing hype.

Love the image and the inclusion of the horse rider as a focal point. Placement of the rider in the frame is great.

Usually too wide an angle and perspective is used but in this case 42mm on a crop camera seems a little too tight. Hopefully you shot this scene at a variety of focal lengths and perspective angles. I would like to see these scene with the perspective of a 35mm or slightly wider focal length and its field of view.

On photo Midnight Train to Georgia in the Photo with a song challenge (24 comments in total)

Overall this is a very nice image. I think it would be stronger with more space to the left of the locomotive. It would give more of a feel that the train is heading off to distant places in the night. It needs more room to run in the image.

The selection of the trestle crossing was a very good choice as the old wood ties in very nicely with the ancient locomotive and this works very well as a B&W image that adds to the old times feel of the image.

Brilliant concept that would be fun to play with, both variations of the shot and alterations to the post processing.

On photo Great Egret and Chicks in the Bird Homes In Nature challenge (10 comments in total)

Great image. Not sure about the caption as it is a little late to be nest building.

Personally I would have tried shooting with smaller apertures with a shorter shutter speed as 1/2500 seems like overkill for birds sitting in a nest and f4 is marginal with a 400mm lens. Would have liked to compare this image with ones shot at f5.6 and f8 to the one posted.

On photo Going Home in the The American Cowboy challenge (8 comments in total)

Image had potential but it is cropped poorly with the horse and rancher dead center in the frame. The cropping takes away a lot of the potential impact. Appears to be a bit overexposed as well and this also takes away some of the atmosphere of the overall environment.

Hopefully this was captured as a raw image file and it is not so tightly cropped. Shows the importance of taking a series of shots at different zoom settings so as to have options later in post processing.

On article Nikon D750 Review (2019 comments in total)

What was overlooked is how when changes are made to camera settings such as aperture, shutter speed, ISO, etc. the entire rear LCD screen displays everything and uses a very large font that is more than 10x what one would usually see on a rear or top display on a Nikon camera.

It is interesting that Nikon put the tilt LCD screen on the D750 but not on the premier landscape photography camera from Nikon, the D810. With landscape shooting and in particular when using live view and a PC-E lens the ability to tilt the display with the tripod mounted camera is a tremendous benefit. Somebody's ego got in the way of adding this feature and functionality to the D8xx cameras.
