Profit!

What I don't understand is... It's unlikely that those old lens patents are still valid. So why wouldn't another manufacturer make them and sell? trioplan is selling for like 1500 usd and I'm sure makers like 7artisan can do it for at least half of the price. It's not like the sharpness of those lenses is in question...

Photoman: I'll wait till the hipsters sell theirs second hand and get it for half the price.

I wish. Trioplan 100 f2.8 for half of the price is nowhere to be found... I think it's legit.

On article Nikon D850 vs Sony a7R III: Which is best? (1104 comments in total)
In reply to:

janist74: I think it tells everything that a Sony mirrorless can be compared to the best ever Nikon. Great job Sony!

There's another point of view. Sony features were clearly ahead of Canikon, even before A7r3, and D850 managed to match Sony's flagship. That's commendable, I reckon.

In the end, one thing that this "duel" shows is that Canon is losing its thunder. No one dares to say that their flagship is amongst the best. And that's something very new.

Wow... a couple of years ago we would be arguing Canon vs Nikon. Do we have a verdict for that?

In reply to:

DarkShift: Sony A7RIII is a nice camera, but sadly the lens lineup is not complete without some help from Canon and its EF lenses =)

Maybe he means in terms of value per dollar, rather than optics? he said "good match". It's pretty heftier to get Sony lenses than F/EF mount available lenses.

Avatar480234: This is more like a fanboi driven list than anything else, regardless of the camera's capabilities.
So if you have a Nikon, even though your camera model is not on the list, naturally you will vote for............. Nikon!

So... you think every poll is not valid? Because every poll is just that: A collection and organization of opinion, no matter if this opinion is biased or not.
There are so many ways to determine which camera is best. You could list the specs, you could see how reviewers rate it (in this sense, A7r3 is better because it has got 90% vs 89% of D850), or you could ask the majority. Each one of these has problems and advantages.

treakj: Why, even though I know that I will not get a better image by purchasing a shiny new machine, do I still crave for it? I hate technology!

Eye-AF is handy, but by "better image" I mean IQ and composition. But I understand, I think that at least it will allow me to not miss. Anyways, please someone stop my hand before I push "confirm order"...

ZeBebito: Besides lab charts, I guess the difference between these cameras means absolutely nothing in real life shooting.

I'd say half stop is relevant.
You have to keep in mind that those limits count when you need it. If you shoot in an environment without extreme contrast, you will never see the difference. But in a high contrast environment, every bit helps to bring a better image.

8/10.
I find this question problematic. If I do an alteration on my photography, I'd do in a way that is difficult to detect. That's why I'll be inclined to be very suspicious of any image that might have an alteration. Some are very easy to find, but if you can't find it, you start to nit pick.

So It's not a surprise that many can detect an actually altered image, but falls short to judge that an image was not altered.

"Recently"? People have been complaining for years.

Better late than never. I'm actually happy they acknowledged it.

I have xt-2 and D750. I know the topic here is cropped sensor camera, but I'll share it anyway.

XT-2 is a very good camera indeed. The controls are amazing, the lenses are fantastic, the body is beautiful and the size/weight is more confortable than DSLR.
But the other day I used the D750 and the XT-2 for a musical theather gig (dark place with lot of dancing), and here's my thoughts:

-> D750 paired with 70-200 f2.8 is HEAVY compared to a XT-2 paired with 50-140 f2.8.
--> The autofocus is much more reliable on D750, the 3D tracking works really well.
--> Even with the updated firmware, XT-2 Sometimes just freezes randomly while I shoot (what the heck)
--> The high ISO images on full frame is better. I saw someone comparing the image quality on those 2 but I disagree that they are similar.
--> WYSIWYG on XT-2 is really amazing.

All in all, I wouldn't say XT-2 has the same reliability than a D750, especially in dark environment. I suspect the reliability of D500 is even better.

sirhawkeye64: I'm not a Canon hater, but I hope that people (consumers) do realize that this type of stuff, while it's great for Canon because it protects intellectual property, but for consumers, it adds additional costs to the product pricing.....

Not that simple. For one hand, yes, what you said is true. On the other hand, you'd need to ask if those technologies would exist if there's no protection of intellectual property.

On article Sigma 12-24mm F4 DG HSM Art Lens Review (275 comments in total)
In reply to:

GrahamHO: Your review states that when used on an APSC camera the focal length of the Sigma 12 / 24 f4 lens is equivalent to 19 / 38 on full frame and the aperture becomes equivalent to f6.4. In fact the size of the aperture does NOT change and stays at f4 regardless of the sensor size. This is fairly basic and causes your review to lack accuracy

@GrahamHo The equivalence topic is not very easy to follow. But it's true. What you mean by "stays at f4" is true, but what they are saying is "in APSC, the lens works as if it is a f6.4 on FF".

To illustrate that, consider that 50mm f1.8 on a APSC. It works like 75mm. But would you say that the DOF is the same as 75mm f1.8? F number is a fraction between focal length and diameter. So, in order to maintain the f number, the diameter would need to increase as well. But you know that changing the sensor size will not magically increase the diameter.

In reply to:

rnmchinnor: Buy a camera and use it. Life is too short to bicker with strangers over technical details that few understand, or about functions that, in the real world, rarely get used. Amateur photography (as it's unlikely that a 'Pro' would use this thing as their first camera') is about seeing and passing on the everyday beauty in things, not gathering gadgets in a box and shouting at people who don't like your box.

Reminds me of religion.

I agree that people waste too much time on some very small details, and oftentimes the details might not impact anything. But the discussion on specs and features is not totally wasteful.

I take and post at least one photo per day, but it is good to know many technical aspects of the cameras or to understand the current technological trends. It's fun and I believe it will ultimately guide how to take photography.

For example, IS makes possible to take some interesting long exposure, handheld photos. The high DR of some sensors makes it possible to take high contrast scenarios. LR new features can bring new possibilities of how to represent those photos. All of those things expands how to take photography, so I can't agree 100% with you. But 70% yes.

jay jay02: So a 6900 will be here in 6 months with an updated touch screen and one thousand AF points.

Yes, I agree with you teddoman. But exactly the "feeling" is the point. I'm not saying that it will, in fact, depreciate, I'm pointing out a potentially harmful effect that consumer might be concerned with short-cycled AND unpredictable product releases. It doesn't matter what reality turned out to be.

But I'm aware that short cycled product release has its advantage for the consumers too.

I have the older 90mm model. It's really a bargain. It's a very sharp 90mm lens , with quick focus (faster than tamron 24-70 or 200-700). It is a very good macro lens. All for a very competitive price tag. I'm happy to know that there's someone that agrees on that. I think it is one of the best lens tamron ever released.

jay jay, I'd say the real problem, for consumer point of view, is that you have the risk to buy something that will depreciate quickly. What if you buy a6500 today only to Sony releases an a6700 with similar price point?

To say the truth, I think one of the reason a6500 price point is so steep is to make sure a6300 owners don't get upset.
