StephanBG: This had to come up again - you can read the headline and think "ah there go the comments again".

With FF dying in the future we also will see an end to this equivalence mumbo jumbo, invented by FF zealots and those who profit from them to show how they have the largest.

And I'm so f* fed up with people with 5 years old FF cameras - with abysmal noise performance to todays standards even compared to APSC - use this mumbo jumbo.

If you use it, go the whole distance and factor your noisy FF sensor in there for "light gathering". And make every Canon lens 1 stop "slower" compared to Sony FF lenses b/c you Canon FF shooters have s* sensors.

@mgrum: "The f-stop is irrelevant except for performing exposure calculations within the same format." That is incorrect. I used to shoot 4x5 and 2-1/4 with the same film at the same time on the same subject. I used the same equivalent exposure for both. If the exposure was correct, both shots were properly exposed.

SantaFeBill: 85mm F/1.2 equivalent to 67mm f/0.9 for DOF, but F/1.2 = F/1.2 for exposure regardless of focal length. Of course, the actual T stop may vary between lenses of the same F-stop.
Sorry to state the obvious, but it does seem to be an on-going confusion. I wish stories would explicitly say 'DOF equivalence'. Would save a lot of posting. <g>

@mgrum: "True, but exposure is a meaningless measurement when comparing sensor sizes." Hardly 'meaningless'. Suppose you're shooting in M mode and using a hand-held meter to get the exposure with both a D810 and a D500, and have both cameras set to ISO 100. Also suppose the indicated exposure is 1/125 sec. at F/8. Would you set a different shutter speed or F-stop on one camera or the other _simply_ because of the different sensor size?

On article Nikon D7500 vs Nikon D500: Which is better for you? (393 comments in total)
In reply to:

Kuzmabrik: I would be one of few people who prefer D7500. Photography and video are my hobbies, I am not a professional. I need good photo&video capabilities in one body + tilted touch screen. D7500 offers me all theese features. It is better than Canon 80D in image quality and has 4k video. I do not need the second SD slot or battery grip because I am an enthusiast, not a professional photographer. I do not consider buying mirrorless cameras From Fuji or Oly/Pani because they have few lenses which are extremely expensive.
So, if you are a professional photographer and want more features - buy fullframe top bodies. If you are an enthusiast and have money to burn - buy fuji. But do not complain) Nobody would offer you a perfect top camera for a low price. Sacrlflces have to be made.

"I do not need the second SD slot or battery grip because I am an enthusiast, not a professional photographer."
There are other reasons besides doing professional work for valuing 2 slots: one is backup when taking shots that can't be repeated - once in a lifetime trip, son's graduation as examples. By using a second card for backup, your chance of losing such moments due to a card failure are significantly reduced.
Battery grips are very useful for long shooting sessions and/or sports or wildlife photography with long lenses.

On article Nikon D7500: What you need to know (536 comments in total)

I use the second slot on my D7000 very often, when I'm shooting events where some want copies quickly and others want more processed results - NEFs to one card and JPEGs to the other. I'm not shooting professionally - these are parties and performances here at our senior facility, and I'm providing results gratis, but two cards makes for a quick and logical work flow. YMMV.

On article Fotodiox Pro launches five GFX lens adapters (79 comments in total)
In reply to:

villagranvicent: What would be the point to use FF lenses with a medium format body? The same thing as when using APS lenses in FF cameras, you have to crop.

@villagranvicent: No, not the same. Think using a 210mm on a 35mm and on an 8x10. Very different what you capture - although the difference between the GFX's sensor size and the 5D's isn't nearly as great as between a 35mm frame and an 8x10 sheet of film, so the difference in the fov wouldn't be as great either.
There'll be someone here who can calculate the actual difference in fovs for that lens on the GFX and the 5D.

marc petzold: I've read it on NR this early morning..what a shame, and loss, waste of Money & R&D for Nikon. Even further, the name Nikon stays now always for this PR Nikon DL Trio Digicam Deaster....i really have had high hopes for the DL 18-50, which is/was unique compared to all other Premium 1" Sensor Enthusiast Cameras, because of having the ultra wide 18mm angle up to 50mm...normal nifty-fifty prime focal length. As we do all knew - the usual suspects from Canon & Sony either way does have a 28-100 or 24-70mm lens, so there is really nothing, no comparsion onto the market, there was no competition for the DL 18-50. It does feature also according to the ads from this model the unique perspective shift mode, to correct skewed perspective and straighten horizon lines.

@makofoto: If you mean the Fuji 16-55, that's only equivalent to 24mm at the wide end on a APS-C sensor.

This is really a throwback (not that that's bad). Did anyone else notice that the film speed is listed as "ASA" and not "ISO"? I remember setting my GE light meter to ASA 10 to shoot Kodachrome.

What an ignorant statement. So Robert Capa, Dorothea Lange, Eliot Porter (The Place No One Knew), James Agee and Walker Evans (Now Let Us Praise Famous Men), not to mention Goya and Picasso, were not 'proper artists'.

On article Adobe Creative Suite 6 has been officially retired (351 comments in total)

I can't image that Lr won't be folded into the subscription model as well. Having to maintain sw with an independent maintenance and update schedule separate from CC can't be good for the bottom line.

James Pilcher: Kodachrome would have been a better choice.

Also, I remember being told that Kodak hired persons with advanced degrees in some areas of chemistry or ChemE to keep the processing in spec. It was that complicated.

In reply to:

Paul Petersen: Kodachrome with an included mailer that returns the slides with virgin scans on a CD/DVD or download link from the web would be the bomb for me.

No, because Kodachrome came back as positives, not negatives.

On article New 20mm F2 4.5x macro lens released by Mitakon (122 comments in total)

Wish they had made it from 2x to 4x - but then it wouldn't be selling for US$199. :-)
Also, anyone thinking about this has to think about the cost of supplemental lighting, as other posts have mentioned.

US$99/month? That's close enough to $1200/year that the difference doesn't matter. Whatever these guys are smoking, it must be potent. If anyone reading about this really wants to invest in it, please contact me first for a great deal on oceanfront property right outside Deming, NM.

Sorry there's no Windows trial version. As a senior on limited means, even a U.S. $40 expenditure has to be carefully considered. Even a 30-day money-back guarantee (as I understand On1 offers for Photo RAW) would be welcome.
