Maximum sharpness achieved? or lens not capable

Yeah, Harron, don't use the infinity stop on the lens, actually focus.

I suggest magnified Live View for landscapes.

Yeah, that'd be useful, Dave - exactly the same photo with two different lenses.

I would like to see the same scene shot at the same time with one lens that's supposedly clinical and another that's not, eg FA35, DA35.

She does, Dewman, and the distortion of the UWA exaggerates 'em.

I asked for some bitchy melodrama in her expression. This was a bit of work for her, because she really is the sweet girl next door by disposition, but she *is* an agency model and being able to do a mood is part and parcel of the business. :)

Fingers were crossed when I bought from eBay in the States an ancient Canon FD 300mm L f2.8 to put on my Sony A7. What if I'd been sold a pup?




I'm a happy camper!

Nothing to be afraid of, Culture, the 70-200 f2.8 for Canon or Nikon is a staple of wedding photographers, along with the 24-70 f2.8. You could run your business with those two lenses.

Everyone tries to be distinctive, so there will be others who add the 14-24 or 16-35 for interiors and special shots.

An additional 85mm prime or 90/100/105 mm macro lens are great for detail shots, the ring, the invitation card, etc and for dreamy individual posed portraits such as the bride getting ready.

Portraiture Gary Fong Diffuser/Flash Modes or does anyone actually do this?

Remember that you're not talking about the exposure on the subject, but the exposure on the background ... the so-called ambient level.

Once you're in a particular room, or posing people against that wall or whatever, the exposure on your camera doesn't need to change unless the conditions themselves do ... the sun comes out, somebody turns on a lamp, whatever.

As a matter of fact, with TTL across any of the brands, the exposure can be thrown shot to shot by reflective elements such as glass or metal, and variation in how dark the background is. In M mode, you get the ambient right with test shots before you start shooting, then just click away once you're happy. You get both predictability and consistency - effectively, you're now doing studio shooting.

If conditions or your locations are changing minute by minute, one of the automated modes then makes perfect sense. My defaults are -1eV for the camera, -1eV for the flash. You're trading off precision for speed, getting more keepers out of candid shots.



Not as such. The background will typically be darker than you want, the subject the same. It's two different exposures, body and flash.

Camera flash algorithms do have to guess whether you want the subject or the scene lit. Canon agonized over it ... I think at one time focus distance was considered in their version of TTL, then dropped.




It's not a correct standard, it's just the default. Like the industry standard 18% grey for exposure, this simply doesn't suit a lot of shooters and their situations.

Quite a few cameras of different brands I've used seem to like to drop the shutter speed down to 1/60 or 1/30s even when using flash in an automated mode, maybe to make sure the background doesn't turn to black. Then the subject can appear to have a floating head! :)

There was so little text for them to write, this review is only as long as it is because it discusses two other cameras.

They shouldn't come up with a 'we can't do X-Trans sensors' for the GFX 50S excuse for the Fuji because it uses the same sensor as the 645Z.

Two things I don't like about the K-1 C-AF performance

IMHO, that's quite shaky guestimates and numbers you rely on Jeff. :)

As in the situation where you said I took pictures of a female runner on the beach at f8, you were wrong.

It was at f4.

And with the cricketers above, there was no 'increasing the DoF'.

That Canon lens is *wide open* at f2.8.

Here is another shot, soccer players at f2.8 taken a few weeks ago with the Tamron 70-200 on the K-1 ...

Of course they're errors in the system, Jeff, failing to track what they're supposed to track. The doll's eye only returns to focus because the photographer had to come to rest to allow it.

I don't think there's a point fetishizing the expensive D5's system ... take away the hype, and DPR found 3D tracking is something uncritical and unskeptical readers might get excited reading about, but it has real problems when shooting, and you need to use a conventional mode instead.

The DPR writer talks up the feature, but in the link below look for yourself at the failure of the Nikon system to track the player's elbow in the shots - click on the buttons labelled 1,2,3 and so on under each picture.

The focus point aggressively shifts to other body parts in the player, another player, and even the uniformly dark background. It's baffling when AFAIK there's a second CPU the owner has paid for on the D5 motherboard that's in charge of this algorithm. What is its excuse for failing to keep up, and why does it choose something that looks nothing like the subject as its target?

As a gloomy Pentaxian, I expected better AF from the Canon 5D Mk III and Nikon D810 on the days I used them ... but I thought, 'Meh'. What was I supposed to be impressed by?

The D5 (it and the D500 have much the same AF system) are enormously priced specialist cameras but you can see from the sequences they just can't replace a skilled photographer.

That starts to be a lot of mucking around, Bruce, you end up where it's more practical to stay in Manual. The ISO stays where you want it, and you'll even get that exposure accurately shown in Live View, so you can see if the bokeh lights or the lamp in the corner are as bright as you want them to be.




Yep. "I start at -1eV." Indoors or outdoors.




Probably. I just leave it there. It's my default under all circumstances, day or night, popup or bounced.



Yes. :)

If you had five flashes, through the camera, you raise or lower the overall lighting of the subject or scene, but you can still go around and adjust each one - lower the level of the snoot on the face, lift up the rim light on the hair, etc.

Sorry, McGregni, but it makes it difficult to recommend a third party manufacturer who admit they they have trouble fixing bugs.

Class A's curious argument was that if the company provided good service to Pentax owners in the past it was ridiculous to think it could be different in the future!

Nicely done. My wife and I paid more to see it at that ancient relic, The Cinema.

We thought Tom Cruise was okay in it, and Emily Blunt was very good. Video gamers will recognize the rhythm of the plot.

Very quickly, Bruce:

1. Set your exposure so the background level is as you want it - go to Manual if you like so that Live View tells you straight away, or take a test pic and chimp. Fix the ISO so the camera can't become aggressive with it.

2. Indoors, the Fong's main illumination will be from the ceiling with the secondary fill from all directions so that the eye sockets aren't panda-like.

3. Work the FEC to taste. You can do it from the flash, I prefer to do it rolling the dial from the customized Info panel as PSchlute has mentioned (note that the flash and camera FEC are cumulative eg -1 and +1 will cancel each other out). I start at -1eV. What I'm usually looking for is to get a nice skin colour - I chimp to get the adjustments right.

You have an odd view, Jeff - that only pros can manual focus!

Below are two shots I did, the first just last weekend with my newly acquired Canon FD 300mm f2.8 on a Sony A7.

Corey chose manual focus because the Nikon D5 autofocus wouldn't be able to track his skateboarder.

Of course you practice your focus range, it's no different from chimping an exposure, if I can do it, you can!

But who'd be telling this, Jeff? :D

The D500 is a specialist camera too expensive for most people. It's more than fifty percent more expensive than the premium Pentax crop camera, the KP, and almost makes no sense when you can get a full frame K-1 for the same price!

You're supporting that primitive image recognition system of 3D Tracking more than Nikon themselves do - they do not recommend it in their documentation, as DPR have pointed out.

Have a look at the Nikon 3D tracking jump around before totally disintegrating on the woman in this clip ...

Company propaganda's one thing, real life performance, another. :)

I saw a video of Rich Corey, possibly *the* action photographer in the world, choosing Manual Focus on his D5 for a skateboarder scene.

Here's that same AF system, but put in the APS-C D500. Watch the focus point get placed out into the grass again, and again, and again.

Honestly, Jeff, if you couldn't do better tracking yourself, you'd give the hobby away!
