On Nikon D750 flare investigated: Why we're not worried article (372 comments in total)

There will be a time when people will sell D600 with oil splash effects and D750 with flare issues as collectors' items.

In reply to:

bensherman: Is Dpreview working for Nikon by any chance? To begin with they missed the whole flare issue,then denied it and now this so called investigation (primitive compared to other review sites) that had to bring Canon in make dpreview feel good about their argument....Plain silly!

In reply to:

Roman Korcek: "The lenses [...] will be available in [...] MFT mounts initially, with the company promising [...] Micro Four Thirds at a later date."

I assume this is a typo or am I missing something?

Let's hope m43 will not be left out...

In reply to:

Langusta: Nice lens but at least some basic electronics for aperture control and focus confirmation (like dandelion chip) should be imo included. Voigtlander could do that why not samyang? It's really no rocket science nowadays...

I think the Nikon mount is chipped

HowaboutRAW: Mr Physics+Frank C:

According to Wikipedia the flash sync speed of the D70 is 1/300 sec.

With a smaller (APSC) focal plane shutter it is easier to build higher sync speeds.

The top shutter speed of the camera is indeed 1/8000 sec.

Speed might even be the same. Exposure time is different due to the sensor size...

tecnoworld: A wonderful camera, its af performance makes me think of going back to dslr, after the poor performanve of even the best mirrorless around, but...I'll wait and see what the a9 can deliver.

I am not so unhappy with Olympus AF and certain lenses. Still, have to see how D750 does

In reply to:

Frank C.: That dumbed down 1/4000 and 1/200 x-sync is hard to swallow nonetheless

It is hard to swallow... That's why I wonder if the ISO 50 could compensate a little for that...

On the other hand I think that would require a differentmaybe larger shutter and would make the camera the same size as the D800/810. It is the reason why I will buy the D750 but keep my D7000

garyknrd: What a camera! Insane sensor. If Nikon had the lenses I like to shoot with. I would make a lateral move in a heart beat.

Yup, that's probably a niche not covered properly

How does it work at iso 50?

In reply to:

Lassoni: I'm confused what you're supposed to do with this camera. To use older lenses? But there are sites online (not just dxomark) that show the older lenses are MUCH softer than any of the newer generation of lenses. Less chroma, less distortion, less fringe..

If someone with collection of older lenses buys this camera so he doesn't have to "upgrade" his/her lenses, why not just buy a different camera and newer lenses? I'm curious.

Using a number of Nikkor Ais lenses, I can tell you they are not soft at all on modern Dslrs, on the contrary. If there is one thing that you need to control is flare.

That said, I use these lenses not because I am looking for the quantified image quality you refer to (resolving power, aberrations and so on) but for qualities that lie exactly in their flaws and their special signatures when used properly. I am sure that if you used a 50mm 1.2 Ais for close subjects at 1.2 you would appreciate it beyond its apparent halos and flaws.

Nicko3052: To all complaining about the OLPF filter (AA filter) in D750 some facts about Camera model – Pixel pitch - OLPF:
D7100 - 3.91 um – OLPF: NO
D800E/D810 – 4.88um – OLPF: NO
D750 – 5.96um – OLPF: YES
A7R – 4.88um – OLPF: NO
A7 – 5.96um – OLPF: YES
You draw the conclusion
Cheers

What he means, and he is absolutely correct, is that oixel pitch dictates the removal of the filter

On Opinion: Bring on the 70-200mm equivalents article (340 comments in total)

I know I will be zapped but in 90% of the use cases my Panasonic Lumix G Vario 45-150mm F4-5.6 on E-PL5 is just amazing. I would love to see the reviews on these lenses and even more the new Olympus but I expect the usual "corners are soft but stepped down to f4 is already much better" or the typical "image at 200 is a bit dissapointing and in fact it is not 200 but rather 180". I think the 70-200 f4's are much better just because of this. I recently met a pro photographer, with some world class prizes going on a mission to Syria. His normal-long zoom lens was a 70-300 Nikon.

On another note: a 2.8 lens is ALWAYS 2.8 in terms of light AND depth of field albeit at a different FOV. And all formats and native lens combinations are full frame.

In reply to:

pkosewski: I'm tried the PL5 body a while ago and thought: if only it had a dial for aperture.

PL7 seems great, but the price is simply to high. M10 is only $100. If PL7 had a better sensor, this might be somehow attractive.
With the same sensor it is just a bit smaller, a bit cheaper, but a seriously inferior camera.

With DSLRs, we pay a lot for features (eg. D3300 vs D7100).
With Olympus the base price for getting into the system is very high, but a very serious "prosumer" body (M5) is not even twice as expensive as a basic PL5/7. But if Olympus manages to earn money this way, then this is what they should do.

I wear gloves for 4 months and carry around the E-PL5 on snowy mountains and sandy beaches.

So far it has proven surprisingly robust (as the whole camera) plus I cannot understand the ergonomics of having a primarily LCD based camera with the dial elsewhere than the back. As I said, I really wish all cameras could make it that easy to change aperture and compensate in one dial.

Absolutely. Which works great and you can compensate exposure in A/S quite easily by just tilting upwards. For me it is ideal both with the LCD and VF-4.

E-PL5 has an aperture dial...
