Are you suggesting that Olympus PRO lenses are less affected by diffraction than other brands?

Yeah, I think you hit the nail on the head with the convention differences. Sigma never mentions anything equivalent to HR or Super HR glass in any of their lenses while ELD and SLD glass seems to ...

I fully agree with you here, ePhotozine has a long history of producing nonsense results in their testing.

Since the E-M10IV is using TrupicVIII hopefully that means that they'll add the new eye detect to the E-M1ii/E-M5iii/E-M1X.

@Panther That's not correct, most of the other manufacturers have the lens correction for pitch and yaw while the IBIS corrects for X/Y-translation and roll. Here the IBIS is only correcting for...

They sort of did already, the IBIS handles roll correction while the lens handles everything else. Unfortunately it seems like the lens uses the same mediocre IS unit from the original Sigma DSLR ...

The lenstip first impressions review of this lens is pretty brutal.

Seems like a mixed bag. On one hand seems like it's sharp at 400mm, weather sealed, maintains focal length at MFD, integrated arca swiss plate in the tripod foot, and construction quality is good....

This kind of stuff, along with ergonomics, is why I could never stick with Sony. I shoot in snow quite a bit and the ability to just drop the camera in the snow while you work on something else ...

Ouch, what happened?

@Pascal Do you have a link to the R5 readout speed being 6x faster than the A7RIV? That would be a really incredible result if it's correct as that would make it faster (1/90s) than every ILC...

@sillen Do you actually know what the readout speed is or are you just assuming?

@Kevin Overall they're actually decent reviewers but they do occasional screw the pooch. The biggest problem I see with the Northrups is that when they get an outlier result they seem to assume...

@RubberDials Do you realize that in the two video links you've provided the R5 is actually shooting a burst with mechanical shutter while the A7Siii is simply focusing without actually taking any...

@JakeJY He did the test with and without the High Temp limit and got very similar results. He even redid the entire test in a 2nd video based on suggestions from comments and got the same results...

It's just how the converter is tuned to the specific black points in the various cameras. Now that Adobe has improved ACR to allow finer adjustments to shadow tint it's mostly a non-issue. Shadow ...

They didn't say that it changes the len's aperture or focal length. Equivalent focal length and aperture are simply used to relate how the image formed by one format with a given lens with compare...

It was actually Minolta in 2003, or 2004 (IIRC) if we only count ILC cameras.

We finally have some official confirmation that the sensor is riding on bearings. Hopefully this should put to rest all the claims that the sensor is actually floating in space. Also seems to ...

That's not true though, the issue with the plot is that the way "ISO" on that plot is defined is not consistent between manufacturers. The Olympus curve is artificially shifted to the right making ...
