About me:

I am a hiker/traveler first, photographer second. I diligently strive to maintain this order of priority. The whole idea behind my photography is to record images of the places to which I travel and hike for future enjoyment. I use the best camera equipment I can afford in order to record those places with as much clarity as possible. I compose images in a way that captures the scene as I am viewing it but I am free to compose in ways that I feel are interesting too. I am not confined to composing for what may be commercially sellable to clueless consumers. I am continuously trying to sharpen and broaden my skills so that my actions do not counteract the clarity and resolution this fine equipment provides. Turning professional isn’t an option. I am seeking to retire, not begin another career.

In reply to:

ThomasSwitzerland: I cannot help. Those samples do not communicate anything what the D750 should be.

They could be taken with almost any camera, even 1” sensor or smaller, by any snap shooter.

I trust <dpreview> as a prime source. But on some of their sample galleries they communicate only one thing: Nonsense. Or said in a diplomatic way: Much room left for optimization.

Again, I am not asking for a test or new test protocol. I am asking for a specific sample. Since you provided one in this series abiding by some of my parameters, all I ask now is that you identify the "extra care", if taken, with future sample sets.

Rishi, I promise you that such a scene will provide much of what an experienced photographer will need to assess across the frame sharpness. As for time of day and the type of day, you'll have to pick a time of day and stick with it and shoot on sunny days only. Yes, this may require shooting some samples on different days. I usually shoot my comparisons/tests during early morning hours where there is still shadow that can be analyzed and mostly cloudless days. These changing conditions are present in your general samples already so not sure what the issue is. This isn't meant to compete with a "studio test" anyway.

If a landscape scene is of limited value in assessing a camera's sensor with regards to the capture of detail and of DR, I can't think of a better one.

Part 2

For lens testing, you will find a link in my forum posts to various comparisons I have made that will give an idea of the correct landscape to use. I use the same scene every time just like DPR does with the studio shot. Wouldn't hurt for camera reviews either. Find a scene location that has as much repeatable features as possible (within the limits of nature of course). I shoot from a bridge in my town that overlooks natural scenery as well as buildings. The height of the bridge puts all corners at infinity up to about 35mm so you can judge corners like a flat wall at least with the WA and UWA lenses. Also provides enough detail to judge sensor detail capture.

Such a scene would not be as informative for 200+ mm lenses I would imagine.

Good morning Rishi. I'm chill baby.

So, there was a sunrise shot on a tripod? I may not have gotten that far. Why the complaints? I didn't know there was such a shot. If DPR is going to provide shots like this every time, I am willing to look at the images but may I suggest that you document which images have enjoyed the extra care, tripod, LV, mirror up, remote release. That way I and others can go straight to them. The only other thing for testing purposes would be to use a decent lens for this particular "extra care" shot.

Part 2

Tripod in controlled lighting shooting a test target at 15 feet doesn't tell everything. I'd like to see one landscape shot per set at the golden hour(s) with plenty of infinity in the scene with a quality lens utilizing all of the measures landscapers employ to maximize IQ. If you can't do it, then own that, but don't go on that it does not matter.

Rishi, 57even's comments seemed a bit childish to me. I get the impression you are employed by DPR (from references in your comments) and if you do not recognize such tone in 57even's comments, I'm a little inclined to believe you are mistaken about a lot more. You must read my comments carefully. I am in favor of DPR providing a wide range of situations and scenes in their sample reviews. However, because reviewers do not or can not provide a sample of every type of situation, the best review/testing remains the one the user does with his own hand and I've said this many times long before 57even ever logged onto DPR or you coming to work for DPR (if you work for DPR).

Liking and unliking is for children or adults too cowardly to put their name on a negative comment. Let's not turn this site into an Ass Book or Twatter.

As for Thomas, I disagree. The samples indicate plenty, good & bad. If I am going to criticize DPR, it's for the use of a cr@p lens. DPR, next time you need to review/preview a Nikon FF cam, I'll overnight you a 24-70G or 14-24G. :)

It would also be nice if DPR would put the camera up on a tripod for a few shots and try to go for optimal IQ.

On Post-Photokina polls - Tell us what you think article (198 comments in total)

I voted for medium format. I would think anyone who has inspected a RAW from this format in recent years and are not blind would have to admit that the IQ is unparalleled by any sensor smaller. Of course, there are many valid reasons to reject MF: price & other costs, capabilities such as high ISO, fps, or portability, and the poor man's complaint: file size.

DPR: thank you for the wide variety of subject matter. Every review should have this spread.

I found some noisy blue skies at ISO 200.

Where's the 4k video samples?

Rick Knepper: Last thing I want is a commercial photographer and his entourage hogging up space at overlooks and other viewpoints and blocking trails. Besides, the permit is a formality. I see very few requests for permits being denied if any. What I don't like are commercial photo workshop operators and their customers. Many are respectful of non-workshop shooters but some are downright rude. And they suck up permits to places like the Wave while individuals go wanting.

I borrowed the term from this article for expediency's sake:

"A proposed directive from the U.S. Forest Service that aims to protect federal wilderness from commercial exploitation may end up restraining photographers as well."

I don't think the national parks should be in the business of nurturing commercial enterprise. A park sponsored video or photo spread of e.g. Yosemite for educational purposes is one thing, but for purely commercial purposes so that the Discover Channel (or whoever) can fill its time slots or the workshop operator can run more workshops is not my idea of the best use of public land.

I am vehemently opposed to permits, fees to enter the parks, and other restrictions to individual freedom and enjoyment of the parks. I am certainly not defending any permit system, I was simply reacting to some of the hand-wringing I observed in the comments to the article and taking the pragmatic view that the permit system exists.

However, I am also vehemently opposed to commercial exploitation that can interfere with an individual's enjoyment. To that end, I favor a complete ban of such activities unless the photog/videog manages to do his work as an individual and support jail time for the violators.

Wye Photography: For me personally, and this may apply to others as well. Photoshop CS2 did everything I needed. Later version added nothing I wanted. I do 99% of my processing in Lightroom so paying a huge amount of money for Photoshop upgrades is just not worth it. I looked around for a Photoshop replacement, used Elements for a while but then found Pixelmator. For around £12 it really is a photoshop replacement, it does what I want it to do without all those features I don't need and use. After a large number of tests the Pixelmator healing brush is actually superior to Photoshop's.

The point of this, I guess, is that there are alternatives to the seeming Adobe monopoly. Save yourself money by looking around.

Thanks Adobe but I think you are an overpriced dinosaur waiting for an extinction event.

I don't understand your thought process here. PS CC can be used for by level of user, and if you want out, stop paying the monthly fee. What RAW support are you talking about? Using LR for a complete PPing solution may be why so many LR users' images look unfinished.

I can't imagine using CS2 for anything. Number one, I'd have to be using an old feeble camera. Two, every facet of PS has been improved over the years, sharpening routines, effects, filters, etc. Not sure what CS2 has to do with a news article on PS Elements.

Many of these comments illustrate the old chestnut: No good deed goes unpunished. I wish DPR would use a moderator to cover the news stories and video features.

On Zeiss introduces 'no distortion' Otus 1.4/85mm article (336 comments in total)
In reply to:

Ruy Penalva: 85mm lens, even so fast, without stabilization, is a invite to hand photo blur.

My experience with fast lenses aside, the samples from various sources prove you wrong. Besides, I don't understand wide open portraiture shooting anyway i.e. one eye in focus the rest of the face oof.

Any f1.4 lens can do this or any photog can screw up the shot, there'll be nothing new with the Otus.

The whole idea behind Otus, beyond unparalleled sharpness, is to produce that sharpness across the frame at the widest apertures since today's sensors are growing in MPs and diffraction becomes a problem at ever larger apertures. Stopping down just to achieve the proper "across the frame" sharpness isn't a luxury we have with a D800E. Diffraction becomes noticeable on Canon's 22 MP sensor at f8.

Sannaborjeson: That is weird.

They show only 3000x2000px samples on their flickr and all the samples are terribly over-sharped. https://www.flickr.com/photos/carlzeisslenses/14833959224/

And for some reason CZ bans people from commenting or asking questions on their photo samples.

No, these photos are NOT over-sharpened least not on a pro monitor set correctly.
