On article Sony Cyber-shot RX100 VI: What you need to know (433 comments in total)
In reply to:

pictureAngst: I was a bit confused by the following...

“As you can see from our equivalent aperture graph, the RX100 VI's lens offers an equivalent maximum aperture of around F8 at 24mm, and it only gets slower from there. Whether this matters depends on several factors, not least ambient light.”

...from my understanding, equivalence is all about angle of view and depth of field, but not about light gathering. That is, if you used this camera and a full frame camera to capture the same scene (in terms of angle of view) then the exposure values would be the same (e.g. 1/500, f4, ISO 100).

So why is ambient light mentioned, if not regarding exposure?

Cheers,

@netmage: not really - the ‘matters or not’ statement is made in regards to the ‘equivalent aperture’ statement, in terms of paragraph structure.

...and a FF sensor, don’t forget that one.

...unless it was about the variable maximum aperture. If so, separating this statement from the ‘equivalence’ one would make that clearer.

On article Leica M7 film camera comes to an end (147 comments in total)
In reply to:

pictureAngst: Maybe Leica realised that if someone is going to spend ££££s aschewing the convenience of digital, that they’ll be more inclined to go the whole hog and deride any kind of help at all, not even a built-in meter.

The Leica M-A should come with a free hairshirt and birch whipping cane, so one can properly punish oneself for one’s art.

Of course I meant ‘eschewing’.
‘Aschewing’ is a whole other level of punishment!

tailings: You *'d the first sentence, then forgot to followup with a footnote.

The second paragraph talks about the asterisk - it’s there as part of the example headline rather than a ‘real’ footnote marker.

zkz5: "using both hardware and software, we can cover [the necessary] imaging circle. The most important thing is precision."

I don't get it... how does positioning the sensor more precisely mean they can make do with a smaller image circle? IBIS means that the sensor must move around in an image circle to do it's thing, so the image circle necessarily must be bigger than the sensor.

Wonder if they moved the sensor back slightly (say by 1mm) increasing the image circle that way?
Since all the lenses focus electronically, and it’s the sensor that detects focus, this could be done without the user ever noticing.
I have no idea if this is viable BTW, just a guess.

In reply to:

pictureAngst: There’s a pretty obvious fix - add the weatherproofed extension grip which presumably seals the entire bottom of the camera.

So, not an oversight but a clever upsell.

...my use of the word ‘clever’ may be swapped with ‘cynical money-grabbing’ depending on your personal POV

tinternaut: Presumably, for a fairly static landscape scene where parallax errors shouldn’t (?) be an issue, this would enable be 5DIV user to expose a little more for the shadows, safe in the knowledge there’s some better protected highlight data in the second photo?

Reading the article, it sounds like the ‘hidden’ image is already -1 EV lower than the ‘standard’ image, so I were to make any adjustment it might be to dial in +0.5 EV so that when I merge the 2 images the result has the same exposure as the camera would have used.

On article Fujifilm XF 80mm F2.8 OIS WR Macro sample gallery (92 comments in total)
In reply to:

Jim King: The description above states "the Fujifilm XF 80mm F2.8 Macro is the first X-series lens to give full 1:1 reproduction." That's not the case, as the Zeiss Touit 50mm f2.8 Macro for Fuji X also delivers 1:1 reproduction and it has been available for over three years now.

I’m guessing when they say ‘X-Series’ they mean Fuji lenses

Not surprised the Oly did so well.

I had the original E-1 which was an AWESOMELY well built camera, so I know when they say they’re kit is weatherproofed it’s definitely weatherproofed.

Link | Posted on Jan 11, 2018 at 20:57 UTC as 14th comment

I had the E-1 with the 14-54 'kit' lens - it had such a wonderful well-rounded quality to it, in terms of build quality (the turn-key latches on the waterproofed doors were amazing) and picture quality (the lens and the 55-200 I subsequently bought were superb in every way).

Inevitably my head was turned by the next wave of technology, but to be honest if events had made me stick with that kit, I doubt if my pictures would have suffered for it in any meaningful way.

All the Calgary detectives need to do next is check Flickr and other photo sharing sites for well composed, sharp, and correctly exposed photos from an M-P and then they’ll know they’re on to an imposter!

Some yellow things make you look cool - like a Ferrari (or a Ducati), or perhaps some limited edition trainers. Or maybe expensive ski gear.

A big shiny plastic backpack? Not so much.

In reply to:

pictureAngst: What is it with reviews of 35mm equiv lenses focussing on depth of field so much?

Even when I shot with fast ‘real’ 35s (including the Summicron ‘King of Bokeh’) it was never my first choice (or even second) for thin DOF shots - that’s what 85s and higher are for.

Am I missing something?

I do get the whole ‘environmental portrait’ thing, and have taken many shots in that style, but most of the time if you’re taking this kind of shot, you don’t want to blur the environment to the degree of it not being recognisable. That’s why IMO most of these shots favour f4 or slower.

IMO the real advantage of a wide aperture wide angle is low light shots, where the rule-of-thumb 1/35s minimum shutter speed and great light-gathering aperture come together perfectly.
