Anyone have a K20D and Lightroom?

Subjective observation but shadows on my K20D did have a noisier quality than my *isDS. Was never a problem though as you noted yourself. Never looked back once I started using the k20D.

Focus Breathing on the D-FA 70-200mm

I've had a search and can only find a few general comments on this topic.

I'm considering upgrading from the Sigma 70-200 HSM II to the new Pentax D-FA, but the reach at 200mm for distances greater than 20-30 metres is important for me. The Sigma is spot on for what I need and occasionally a touch short. I'm wary about upgrading only to lose my most commonly used focal length.

Could someone post a couple of photos that compare the two at these ranges or alternatively, provide a definitive comparison?

The alternative for me is to keep the Sigma and add a DA300 to my line up but I won't be doing both. Thanks in advance.

Is your car a public or private place?

In Australia, the law is currently generally concerned with the use of mages rather than the taking of images when it comes to non-commercial situations. A person taking images for private purposes in a public place generally has little to worry about unless the private use violates privacy or child protection laws. I've studied the laws in my State fairly carefully as I have kids who play sport and I occasionally take landscape photos for my own purposes. I don't post photos of people, nor of personal property as a consequence. I also always ask if I know an image of someone else's kids is going to be used in say, a school newsletter, or I crop them out.

In Australia, if you don't post, don't sell, and respect people's sense privacy you won't have any problems. Nevertheless, photographing someone in a car is asking for trouble in that you're likely to violate their sense of privacy without necessarily violating their right to privacy. They may not have a case to stop you but common decency needs to apply. The more people feel their sense of privacy is under threat the more likely it is that laws will be introduced to regulate the activity.

I've found the laws and the cases testing them are more complex than can be covered in a forum post. Being careful, considerate and applying common decency is the way to go.

If I was the OP, I wouldn't take the photo even though I would be legally able to do so.

They're good. You've found a nice spot too.

I find that cityscape panos need a lot of luck. You can shorten the odds by pre-setting the camera in a user mode and taking the tripod and camera with you to places and appointments that put you in proximity to a viewing location at the right time of day. If the sky is behaving you can excuse yourself and have a crack. I recently pulled one off that involved 15 images of 15-25 second exposures in Sydney. It's normally busy but on this night it was well lit, empty and I had my gear in the boot (trunk).

Another tip for your first one. Half an hour before sunrise on a clear sky, a 30sec exposure will pull the deep royal blues from the night sky. For a period of about ten minutes, the exposure of the sky and reflections are perfectly balanced.- no filter required. To the eye the sky looks almost black but a 30 sec test shot will give you a lead on when the sweet spot will happen. The sky brightens fast though so you need to pan from east to west.

Nature Thoughts and criticism

I would've gone for a tighter zoom (>35mm) to get past the reeds on the right. Getting a light burst like this without filters means you'll heavily underexpose the foreground so you need to manage what ends up being black space. I've attached a symmetrical horizon crop to show what I mean. I'm guessing the reeds looked more attractive to the naked eye at the time.

Try this location but just after the sun goes down and see how it goes with the sky turning mauve or clouds glowing pink/orange. You'll be able to get a longer exposure which will smooth out the water some more and expose the land. You might need a grad filter to balance the sky and water though. I struggled with these scenes until I started using filters. You can frame the three clumps of semi-bare trees too.

Try using

The Cokin filters have a removable mounting plate. I have one that fits the FA77. I'm guessing the others have the same features.

You'll need to buy the plate separate to the standard 77mm that comes with the standard offering.

Pose someone in the frame. Ask them to sit on a sea wall and stare off into the distance, then use their silhouette or profile to effect. 3, 8 and 11 could be captured that way at the right time of day.

8 & 11 for 'Special Place.'

6 is the best of the set though, just can't see it fitting the brief.

It must be one of the most heavily photographed locations on Earth, but yours is one of the better ones IMO. The intersection of different curves and sand flow seem to make the difference.

Go to 'Memory Card Options' in the first menu screen after hitting the 'Menu' button. It should be the first option in the first menu, then select either the first or second option. You've selected the third.

This is good advice. Try it on your target subjects and see how it goes. Years ago when faced with the same decision, I found 300mm was a touch too long a touch too often for what I was after. A bit of cropping can resolve short legs especially when the lens is sharp.

Shoot RAW and then use PS or Lightroom to convert to B+W.

If nothing else, the engineering required to propel and manoeuvre 10-20 tonnes of alloy with air and kerosene never ceases to impress (talking jets of course). The older it is, the more impressive.

Watching where that goes with some interest, but sort of hoping it does go by the wayside despite the expense. It just never seemed to be the right fit for the RAAF, unless there's a future contract to cover the air superiority/air-to-air role.

A3-142 gate guarding. Captured before the gloss gets baked off (which generally doesn't take too long). I wouldn't object to my taxes going towards a decent roof for the aircraft standing in front of this base. Given the base is a technical training facility, they'd be advised to put a proper scheme over the Sabre and Mirage; they look terrible.

Laugh now people, but AI is already here and shaping our society. Chat bots are already used across all sectors as chat room operators. Last time I used one for banking I was redirected to a 'human' who during the course of the discussion revealed that the chat room operator was AI. It was good. I reviewed the chat log and still couldn't tell. The diversion to a human was triggered by my request for a moderately complex calculation on a mortgage. In that case I was impressed but it got me thinking that my sense of customer satisfaction has probably contributed in some way to the end of someone's job.

If it hasn't already started website moderators will be fertile ground for the utilisation of AI. In my industry AI is already being employed as a tool for tactical decision making and it's a good thing. Safer, more efficient operation is the outcome we're seeing.

In the not-so-distant future when AI is used moderate photography websites, magazines and newsfeeds, people like us might be pondering (or lamenting) the loss of an art form.

Anyway enough of the sombre tone. It liked my good ones and didn't like my duds. Not bad for a piece of code.;)

Rain/snow/humidity + Sigma 17-50 and other non-sealed lenses with motor

Keep it in the garage a few hours before cold shooting to ensure it doesn't condense internally and minimize unnecessary zooming. I've taken mine out in snow and sleeting conditions without any issues. I wrapped a handkerchief around the barrel for extra protection and used an umbrella when not shooting to keep everything dry.

Ultimately it's not WR, so it's a risk. My logic is that I could afford to replace the lens three times over before it's worth buying the Pentax equivalent. I'm still on the first lens and it's still performing perfectly.
