On article Sony a7R III added to studio scene comparison (371 comments in total)
In reply to:

Sergey Borachev: Why doesn't DPR just use the same physical lens when possible, e.g. The same Canon 85mm lens mounted on the Sony camera as well as on the Canon camera?

I am no expert but from what I have read a canon lens on Sony will never match entirely the performance of the same lens on canon. An adapted solution is generally a compromise in quite a few ways and IQ is one such way.

I can't find any sort of data to support my claims but the corner performance in general is the one most affected on adapted lenses used on Sony.

Unfortunately it's not an ideal situation. The Sony canon adapter has some tolerances which can affect IQ.

One option is to use a sigma lens that is available on most mounts but that too has issues with sample variations depending.

Jefftan: those shot don't seem any different than my A6500 and 10-18mm (or EF-S 10-18 if one like Canon)
Only difference is F4 vs F1.8 and APS-C vs full frame

huge difference in weight and price
worth it or not you be the judge

i said not worth it, I don't need thin DOF (look ugly to me)

F1.8 only use to me is for low light can use 2 stop lower ISO (tolerate the thin DOF)

@Jefftan - Landscapes is such a huge broad term and many people hate UWA lenses for landscapes as they use tele lenses instead.

UWA lenses 'can' be used for landscapes also but creative people can use them for so much more. And with a far larger aperture you can do much more.

Astro work is another application for this lens.

aarif: much better it was a 1.8 with AF for 600$, Sigma would start to sweat a little

The manufacturer decided to make the worlds fastest 135mm lens. Don't think too many people will buy it but they just wanted the headlines.

A 135mm f1.8 lens with AF for cheap is nice but AF is just sooo difficult for Canon and Nikon systems since you have to reverse engineer the AF. Its easier to make it for mirrorless like m43 or Sony since the mount specs are available and you don't have to guess work everything.

Lol 3.4 ev is massive in photography! :p

Jefftan: if use this lens in F11 for landscape htan this F1.8 is a total waste

Paid high price and heavy weight for that F1.8

One guy in my neighbourhood has a Ferrari. And I don't think he can go very fast in a city where I stay. Same thing here. Sure you may not use f1.8 often but it's there if you need it and it's a sharp lens never the less

TN Args: Good to see the crop-MF sensors are competitive with the best of FF.

^^ Well its coming next year and its public news so camera companies can plan on releasing new models based on the new sensors.

You haven't bothered to comment on the fact that you are comparing a few years old so called crop medium format sensor to the latest FF sensors available in the market today

LiangMing: For $1699, you may get a full frame Canon 6D MK2.

Well he/she who is looking to buy from scratch can bloody well make up his/her own mind !

Do the person want IQ if so then 6D mk 2 is better. Does the person want a much lighter birding/wildlife setup then the G9 far out performs the 6D mk 2.

Does the person want lots of smaller high performing lenses then again the 6D mk 2 falls behind.

Yeah Sony has already announced new MF sensors with 100 MP in this so called crop MF format. This is a very old so called crop MF sensor now.

stevevelvia50: An interesting article on m4/3 Olympus EM 1 verses the Nikon D 810 prints. Without high res mode.

http://www.thewanderinglensman.com/2014/02/the-practical-difference-between-full.html

^^ Yeah seriously I thought there were very small differences between sensor formats until I actually had both APS-C and FF. I would never want to shoot APS-C again. A bigger sensor is usually just better. Of course other aspects of m43 are really great like size and portability. However if you want the best IQ you simply have to ignore m43 since you simply aren't going to be able to beat APS-C forget about FF.

In reply to:

rockchalker: I want to thank all of the anti-m43 people on this thread who have posted substanceless complaints about sensor size. You have done nothing but generate interest in this camera and the m43 format.

Everyone knows there is no image quality difference between m43 and APS-C formats. There are minor differences if you shoot at a ridiculously high ISO. You can verify this using the dpreview image comparison tool.

So, again, thank you for your efforts in promoting the m43 format.

Lol 'Everyone know there is no image quality difference between m43 and APS-C' !

There is but if you can't tell the difference then good for you be happy with what you have.

I know a few people who had both. All of them sold off their m43 gear. Only one friend has stuck with m43 for years now but he mostly shoots his lunch and dinner and shares to instagram.

Oh my God please stop these lunatic posts. This camera has a m43 mount and is more meant for people who have m43 gear. Sure you can buy a 6D mk 2 but can you attach any m43 lenses to it ? Well the answer is no you can't so stop with these idiotic posts.

And a 6D mk 2 can't compete with the features available on this cameras. If the fast fps, 4k video and other features aren't useful to you then this camera isn't targeted for you.

In reply to:

junk1: Can the sensor be slowly shifted to track stars? I think at least one camera has that feature???

Dpreview covered the pentax pixel shift long back with multiple articles. However fanbois don't seem happy dpreview found fault with the AF tracking test of the Pentax. Same thing happened when dpreview faulted the A99 II tracking tests.

In reply to:

Pooya Rastin: The camera saves individual files separately. So for those who complain about artefacts: you can add the individual file as a new layer on top of th pixel-shifted image and by masking fix those artefacts.

Most of the complainers don't seem to be people who care about IQ. Those who want max IQ and have a scene that can take advantage of this feature need to work a bit to get max results.

Of course with the 0.5 second delay between shots means the use of this is limited to what you can shoot for sure it's not completely useless as so many whiners are saying.

eazizisaid: @dprstaff, my Sony A7 resolve better details in the studio comparison... I think you should redo the test with the 55 1.8

Or use the Sony 85mm f1.4 GM at least if they want to stick with only 85mm lenses.

jwasturias: I added the Sigma SD Quattro H to the above comparison tool.
If you look at the last line in that newspaper section, it is also clearly readable. Without rainbow color scattering in the B&W text.
Better than my a7r :( and also better than the a7rii and K1 in non-pixel shift. The picture is smaller but sharper. I have never used a sigma camera but on the face of it, it looks like a great landscape camera.

Sigma foveon cameras where always great in terms of low iso IQ. However usability was generally horrible. They are very painful cameras to use but you do gain improvements to IQ that Bayer sensors cameras lack.

In reply to:

aris14: To my opinion K-1 does it better overall.
And in less than 2/3 of the cost.

K1 was the pioneer in this and while I don't think it does it better you can't deny that the K1 is at least equal to this camera for a lot less.

However of course you get a far better rounded camera with the A7rIII with far better AF, video and lens support.

And better support too since Pentax is the only camera manufacturer that isn't available in my country at all.

In reply to:

russbarnes: You say 'landscapes' but of course we already know this is useless for landscapes and the idea of using this feature for such subjects has already been wildly debunked. You subject has to be COMPLETELY static and there isn't a true landscape where that is likely to apply.

While this isn't something I will use a lot it can be useful in certain situations for sure. And for advanced users the 4 RAW files are all available so those who know what to do can clone out any artifacts and get a sharper photo than whats currently possible today.

^^ I would wager it has the star eater syndrome. Sony seem to be very reluctant to do a small fix that wouldn't take much effort at all since my A7rII didn't have the star eater syndrome till 2 patches back.

On article Panasonic Lumix DC-G9 first impressions (394 comments in total)
In reply to:

goblin: A deliberate closure of what was supposed to be an open system:

- Olympus announces pro lenses that mirror Panasonic's existing offers (at least for the 45mm f:1.2)

- Panasonic coughs up a whole fully blown alter ego to the Oly OM-D E-M1mk2, just for the sake of giving owners of Panasonic lenses drooling over Oly's dual image stabilization a Panny body to attach their lenses to (as Dual IS works only within the same brand - Oly lens + Oly body or Panny lens + Panny body).

- Owners of the legacy (rare but excellent) Panaleica 4/3 lenses have only Olympus (E-M1 & E-M1ii)'s shoulder to cry on if they want decent AF performance with their lenses via adapter. Owners of other (read: Zuiko) 4/3 lenses are, of course, set to stay with the E-M1 (& E-M1ii) because Panny would implement anything short of Depth From Moon Craters AF, as long as it's not standard PDAF to handle legacy (and non Panasonic) lenses.

All of this instead of working on making both companies' dual IS cross compatible.

^^ You are comparing apples to oranges !

Panasonic and Olympus jointly launched the m43 system and many expected that both would collaborate to grow the system as 2 heads are better than one.

However sadly its not the case and they are both behaving like hard core competitors. No one expects NIkon and Canon to join hands anytime soon but people expected Panasonic and Olympus to compete less with each other and instead concentrate on really improving the m43 ecosystem.
