Hi all,

An update: I have now written a free software utility (Mac only) to fix this problem for affected images — that is, images you've already shot which exhibit these artifacts.

Here's some informal documentation (overview, limitations, instructions, examples,…[Read more]

Ok, here is an example of a really bad version of the effect. This was a test just out my window with the Hasselblad 350mm. These ship lights are extremely high intensity, but this is still not an effect I like to see! I have also seen it occasionally with the 120mm, but not that often. Only in night shooting with very strong lights in the frame.…[Read more]

Very nice Jack. That is an interesting technique, and it seems to really do the job! I have not tried anything similar. I have been doing a lot of long exposure night work for the streetlight series I am doing. The S2 has worked very well for it. The only problem I have had is with ghost images of the light sources. Since I am not using filters, I…[Read more]

This is a 60 sec exposure with a 35mmS at 320 ISO f4.8

I used LR to color correct the sky and photoshop to quadruple the star brightness.
In 60 seconds the star trails are pretty short.

By quadrupling, I did a color select, selected the white of the stars, Duplicated the stars three times and moved the dupes sideways to get four times…[Read more]

I assume since you say you are a Leica Guy and in past posts looking for an MP and noctilux, you might not have any Nikon lenses? And you certainly appreciate Leica lenses? And if you are a Leica Guy you can afford both options?

Next I would ask what you are going to be using the camera for? If sports, go Nikon.

But I detect that your…[Read more]

superb clip that is a very valuable lesson for the faint hearted..
gives confidence
thanks David.

Hi Stephan and albireo_double

The big problem is the Chamber size and if you use a ‘blower' there is more dust to churn up..I was told that stubborn dust should be removed with the excellent Pentax Orange OCK1 if you can get one and wet Swabs for…[Read more]

The only irritating aspect is that the sensor attracts a lot of dust (as bad as the M9) and cleaning does not help much as I get spots immediately afterwards, when shooting at f11-22. An ultrasonic cleaning system would really be helpful here…

same for me here, don't know why this sensor is so difficult to clean

Dan

Dan,

All ASPH lenses are marked as such on the front of the lens.

David Farkas;1807 wrote: The Contax 645 lenses use an electronically controlled aperture with no manual ring on the lens, whereas other lenses like Hasselblad V and Pentax 67 have mechanical aperture rings. If you had a simple adapter (no electronics), you wouldn't be able to control the aperture setting when used on an S2. I've had some…

Jaw dropping good, please don't take my words lightly 🙂

I bought an ex-demo S2 from the Leica shop in Vienna. Had two hot pixels which showed themselves through vertical lines running across the image (why they were not spotted when the camera was their demo, I don't know). Camera was fixed free of charge within a week (sensor replacement), including shipping. I also had the top LED display changed…[Read more]

velmi pekne fotky – gratulujem!

I am also very much interested in using the Contax 645 lenses on the S2 and wondering why no adapter exists (is it physically not possible to make one or are marketing reasons at play?). I'd love to use the 120 Apo Makro in particular – I had great results with it on the Contax 645 body with a Sinar eMotion 75LV digiback.

Thanks. 🙂

Could you tell us how you sized it for the web and what approach you used for downsizing and output sharpening .

I have sharpened the original file very strong with Nik's Sharpener Pro 3.0 (output sharpening) as I knew that I will downsize it massivly in Photoshop for the web. So first is sharpening…[Read more]

Thanks this makes perfect sense .

Mark ..still laughing about photographing fire flies

The longest possible exposure is at ISO 160. As the ISO increases, the maximum exposure time decreases. I don't think there is a way to get more light into sensor than 125 seconds at ISO 160 or the equivalent combination if time and ISO rating. Also, the resulting images look pretty much the same as far as noise goes – regardless whether it is…[Read more]
