Problems with Tapatalk?

I'm new here. I have tried twice now to post a new thread using the Tapatalk app, but always get an error. I have been able to reply to existing threads, b7t cannot start a new one.

Is this a permission issue? A known forum issue? Or a bug in Tapatalk? I wonder if this thread will post? I'll post the error I receive below, if indeed I am able to create this thread...

Nope, this didn't post. I just registered on the website. Let's see if this works... Posting in 3...2...1...

Test: the advantages of oversampling: 24Mpx vs 61Mpx FF
« Reply #21 on: December 27, 2018, 05:24:53 pm »

Some people prefer big pixels. My conviction is that in the sensor + lens system, it's better to have more Mpx than the optics can resolve, than having more optical power than the sensor can capture.

First reason is you pay the extra sensor resolving power once, and enjoy it with any lens. Second is more real information can be captured with good optics, and less possibility of moire artifacts.

The only disavdantage I can see is a higher need of resources (camera and computer CPU and memory). Even noise and dynamic range don't seem to suffer when smaller photosites are used.

Test:
- 24Mpx FF camera: Sony A7 II vs
- 61,5Mpx FF camera: Olympus E-P5 (same density as a 61,5Mpx FF camera)



Same lens, scene and aperture: Canon 24mm TS-E II @ f/7,1:



200% crop on 24Mpxv FF sensor:


200% crop on 61,5Mpxv FF sensor:




Oversampling avoids moiré and captures much more real detail with optimum lens and shooting conditions.

PS: RAWs look dull because were developed 100% neutral (no bright, contrast or unsharp mask). Once they are processed capture quality arises:

In Australia, we call them 'hoons' - people who have fun in loud cars and drive dangerously. This hoon left his monogram for three house frontages, ours included. Is it art? Disputable, but it captures the theme. It got some reaction on social media.

Thanks

Light in the tunnel

What does one do when waiting for a car to have a front end alignment? Explore the locality of course. Here's to phone camera and tunnels - the way the light plays in them and even the way colours jump out in relief from the dark walls.

Wtb - Arca R mount 120-210mm
« Reply #30 on: March 02, 2019, 10:22:04 pm »

I am looking for long lenses for my Arca.

A schneider 120 APSH is high on the list.

Then a 180 or 210 to complement it.

Please get in touch if you have something available.

Thanks.
