Seagate 18GB 12.54%... I am glad I read this as I am planning for a large capacity HD.

The shot inside the carcass with an Olympus... there is no "Lumix" 8mm f1.8 lens... so that is either the Oly Pro or the Lumix 8mm f3.5 lens. Its a bit strange that information can be printed so incorrectly... great shot either way though... same for all the others too.

In reply to:

Toni Salmonelli: Question to X-T3 and X-T4 users: My X-T2 struggles with AF accuracy in low light situations no matter which AF mode or which lens. How do the X-T3 and X-T4 perform in this regard?

I feel AF is a key performance feature and am surprised a 88% Gold Award camera has several caveats re AF, not just the usual "AF suitable for sports or not" summary. If I ever wanted a X-T4, I think I would need to do some research on which lenses do and don't work best re AF. This issue has been a theme for a while with Fuji... why?

An amazing halo product... I imagine it will be perfectly sharp right into the corners wide open. I wonder what the price and dimensions would have been if it was AF and with IQ merely "very good" instead of perfection? Somewhere between this and an AF f1.2 50mm... half the size and cost? I think they will sell enough to make a nice profit on the whole exercise when you see how many well heeled hobbyists own 600mm f4.0 lenses at 50% more cost. I hope it raises the bar for Leica and Zeiss and is the new sharpest lens ever made, not just one of the fastest.

Looks like that lens has a lot of smudges on the front element!

Wow... so where do I buy this newfangled camera that makes f1.2 DOF out of my f2.8 lens?

New support for Sigma 56mm f1.4 for Sony E mount but not m43... sigh.

In reply to:

MILC man: "the universal failure to offer some sort of AF illuminator target for mirrorless cameras remains a major shortcoming and means mirrorless can't compete with the best DSLRs in some shooting situations."

the latest sony flashes have a separate white led light that apparently turns on just long enough for the camera to focus, right before the shot is taken, see it working here: https://youtu.be/4Np4qLVDEok

so the only real complaint is that it's a brief white light, instead of a colored cross-hatch pattern, like dslrs have... the white light probably functions better for af purposes, but it might be more obnoxious to the subjects.

Nope... the white or orange AF assist light either from mirrorless camera or modern flashes is NOT a fraction as good as the DSLR red near infrared laser pattern light.

Obviously there are a lot of photographers who are too young/ newly inducted to know what DPR is talking about... sigh...

BobT3218: Not sure what the writer is on about exactly. I have an Oly E-M1 with a pre-mirrorless FL-50R flash and the AF assist works fine in both full mechanical and first curtain electronic (anti shock) shutter modes. However, flash is disabled on full electronic (silent) mode because of the rolling issue. How is this something missing from mirrorless when DSLR's don't have any form of electronic shutter?
Also, I believe it has been established elsewhere that with wide open apertures, mirrorless are actually at an advantage in low light.

I can assure you the red AF assist red pattern does NOT work with the FL50R and EM1. The poster is confusing it with the camera AF assist beam. This is what the problem with the article is.

random.lt: I remember very well how good (by those days) was Sony F717 Laser grid for autofocus. That camera did not have a mirror, it focused with contrast detect autofocus. Still, it could focus in total darknes..
Bring back the lasers!

Yep... that generation was amazing for AF in complete darkness and even on a blank wall if you tested it (I know blank walls are not subject matter but it proved how good it was).

ALL flash units made for DSLR cameras will have the red pattern near infra red laser AF assist light DISABLED when mounted on a mirrorless model. The other functions will work as normal. Flash units made for mirrorless cameras (made AFTER a mirrorless model was launched) only have a AF assist light which is like a simple small torch... NOT the near infra red laser PATTERN assist light that only DSLR cameras can utilise. DPR did not make this crystal clear in this article.

SteveCooper: Sony's DSC-F828 8MP Cybershot introduced back in 2003 had/has a Hologram AF (laser pattern). This camera had so many cool features in it's day- I wish today's cameras had the laser Hologram AF, DSLR or mirrorless....

Correct... it was bulletproof AF in low light. I seem to recall that it was withdrawn as it went a bit too far as it could potentially harm an eye.

I get by with mirrorless and flash at weddings. But the red AF flash pattern made focus and speed MUCH better in many situations. With mirrorless, dark dance floors and reception mean you have to find a bit of detail like the boundary between a black jacket and a white shirt. With the red AF pattern, the camera would focus on the white shirt and usually a black jacket as well. The mirrorless AF assist light will not allow the camera to do this.So a little bit of time lost setting the shot up to help the camera AF to work vs literally point and shoot to capture a moment. It has never been explained why the mirrorless AF assist light does not have a pattern as logically this should help a camera with a cross pattern AF sensor.

There is a secret sauce for CAF and mirrorless that Sony has managed to protect the recipe for. I don't know how the algorithms are protected but I would have thought it would be possible to copy or pick apart. It seems maybe not... only trial and error and experience will improve the breed.

davesurrey: Does this fit on the camera hot shoe. In which case could it be used on cameras other than, dare I say it , Nikon?

Correct!

glassoholic: I use the Olympus EE1 dot sight and it is invaluable for handheld following of fast BIF. The new 500 5.6 PF is light enough to do this so a perfect pair!

There is some play from the hot shoe mount not being 100% precise. I have marked with white out on the dot sight the average calibration for medium distance and after fixing the dot sight it is just a couple clicks this way or that and sometimes nothing to be back in business.

On article Leica Noctilux-M 75mm F1.25 ASPH sample gallery (285 comments in total)

I am not sure if a top 85mm f1.4 in comparison would look "almost" as good but these shots are sublime. I suppose the old law of diminishing returns is strongly in force here... How much is the best worth?

I also would not be surprised if a clinical review from say Lenstip would reveal fewer lines per mm of resolution than some 85mm f1 4 lenses but sometimes "flaws" are intentionally designed into a lens.
