Finally I have good weather and time to play... so wanted to give my SD10 a spin. Beginning this week, I brought it to the local camera-store for a sensor-cleaning, as my test-shots taken earlier this year showed sensor-dust issues (or at least, it looked like it); I have 2 pictures Yesterday I got the camera back. I was a bit surprised to find more or less the same issues as before, mostly on actually the exact same pixels of the image. Below a few images to show the issue. All files...
I have four Sigma cameras and their LCD's (quoted from the manuals) are: SD10 1.8" 130,000 dots. SD14 2.5" 150,000 px. DP2s 2.5" 230,000 px. DP2M 3" 920,000 px. Can someone please resolve the above numbers to some meaningful common metric? I ask because some LCDs are expressed in dots meaning sub-pixels just like your TV. Others are "field-sequential", whatever TF that means. Others might even tell the truth, like my NEC monitor with it's 0.265mm group of 3 sub-pixels which comprise one real...

Guy's, I have been a Sigma shooter since my day's with the SD10, I liked my SD15 with 24-70 EX (non macro or OS) combination the best of all but that went into the Shropshire Union canal with me when I fell off the side of a narrowboat back in 2014 and was duly replaced with a SD1 which was great but mine did not autofocus too well with Art glass. I eventually sold my SD1 and all my Sigma glass about a year ago after a dummy spit with the Australian importer of Sigma products who at that time...
I use RawDigger a lot to see raw histograms in order to check exposure, noise, etc. I notice that each model that I have, or have had, saturates at wildly different levels: SD10 at roughly 10,000 but with outliers up to even 20,000. SD14 at about 6,900 but with outliers up to maybe 10,000. DP2s at about 2,300 but with no outliers. SD1M at about 4,080 but with no outliers. All these numbers are derived from 12-bit ADCs, so the Merrill is the only one that makes any sense! Quattros come with...

I wish to measure the saturation-based ISO (EIsat) of a Sigma DSLR empirically. The ISO Standard is a horror of jargon and contains a good few assumptions to boot. So, instead: I have a lux-meter, a very large diffuse source of light (big blue sky), a Sigma SD10 and the excellent RawDigger. Am I right in thinking that the Inverse Square Law does not apply to the lux-meter reading because of the "size" of the sky? In other words, the lux-meter reading should not vary significantly with height...
I am pleased to announce that I have just become the owner of a Sigma SD10 and a bevy of lenses. This boon was bestowed upon my humble self by another member here... :-D I have checked and found that it has firmware V 220.127.116.112. Is this the latest for the SD10? If not, how can I get the latest? Ta. atom14.
Hi gang,Very long time since I have frequented this forum.I have an SD10 and I think a 15-30 and also a 50mm 2.8 ex lens that I'm wanting to offload as I simply don't use it.I thought about selling some time back but never got around to making it happen so now I'll either give it away or toss it.I'm really not sure if there is any interest given that it's old tech but I thought I would offer it to any Sydney based togs before I toss it.It has a catz eye focus screen btw.Anyway, if there is...
Once I saw what these 16 artists could do with pencils, ballpens or oil painting, I thought of spending less time trying to understand different X3F RAW ranges... 16 artists who make believe their works are photographs ...In all seriousness, I am still interested in looking at the actual noise values in an SD10 X3F and I set manual mode, ISO 100, 1/6000s exposure, yet when I push the shutter button fully, it keeps flashing 30 no matter how long and nothing happens. The DP1M took a picture...
The question assumes 100% fill factor and round :-O pixels, to keep the question simple. Let's say that, for a particular set-up, a CoC calculation (rightly or wrongly) gives a value of 0.014mm at the sensor but I insist on using 2x2 binning on a Sigma SD9 or SD10 giving an 0.018mm 'diameter' pixel. Would the DOF be that for 0.014mm or that for 0.018mm? Putting that another way, does the sensor pixel density px/mm^2 have an intrinsic DOF when projected out to the subject plane? I'm thinking...
