    SIGMA SD1 shots

    Could not find a dedicated thread for the Sigma SD1, so here is the start of one. I hope it grows over time!

    Re: SIGMA SD1 shots

    Has anyone seen any image samples taken with SD1 + 50/1.4 Art? I can't find anything even on Sigma's special websites. I'd like to check out some RAW samples and hear user opinions about this combination and whether it offers the clarity of DP3M @ f/2.8.

    Re: SIGMA SD1 shots

    I have a SD1M coming, not that there's any good shooting round here.

    It's coming with a 17-50mm EX DC OS HSM. Any good?

    Great!
    That lens may not rival IQ of DP primes, but more image samples in this thread won't hurt

    I have the SD1 and the 35/1.4 Art lens. As soon as I can, I'll make a RAW file and put it up for inspection.

    Re: SIGMA SD1 shots

    Darr, I'd appreciate if you can share a landscape shot at f/1.4 & f/2.8 to evaluate sharpness.
    What's your impression of AF accuracy at f/1.4?

    Marlina DZ,

    I will do my best to make a landscape shot as soon as I can.

    As far as AF goes, I purchased the lens used in December, gave it a quick tryout in my backyard, then contacted the seller to say, "thank you", and stowed it away. So not a whole lot to report other than I saw no problems with the lens on my initial tryout. Like I said, as soon as I can, I will go make a few landscapes shots and will shoot at 1.4 and 2.8 for you at your request, although they are not what I normally would shoot a landscape at.

    Kind regards,
    Darr

    I ended up with 3 similar lenses and have been doing shoot-outs this week. Just test shots, nothing worth posting. With the higher resolution Merrill sensor, lens comparisons become more meaningful - compared to the SD9 where you can slap any old lens on and almost ignore the effects of diffraction!

    But, anyway, the 17-50mm ended up almost equal to the 18-50mm f/2.8 macro, with a slight edge going to the 18-50mm for IQ, close focusing and curved blades.

    The 24-60mm DG f/2.8 came nowhere near those two

    Re: SIGMA SD1 shots

    Here's a puzzler:

    A LO res raw shot of our street, opened in RawDigger with the over-exposure detector set to 4059 [sic] while investigating some banding:



    As Crocodile Dundee might have said "Banding, mate? Call that banding? etc."

    The sky was lightly overcast with only a slight range of tones in it.

    Any thoughts?

    (no comments on saturation, please, that's how RawDigger renders raw data as RGB without SPP's heavy matrices).

    I have no explanation as to why X3F Merrill files suffer from banding that much. It was a real problem visible in some random shots until Sigma introduced the latest version of SPP 5 that took care of banning very well, better than other plugins could.
    Ted, show us your final/processed image, please.

    Sure Malina, this is the TIFF out of SPP 5.5.3, converted to JPEG for posting. LO res shot is full size.

    I usually go from SPP as a 16-bit ProPhoto TIFF to RawTherapee for keeper images. I shoot LO because I don't print and I view on my monitor only.



    Hmm . . should have downsized it but not sure of the image posting rules here. Over on DPR, they think nothing of posting 4704x3136px Merrill jpegs!!

    Anyway, there is some slight tone variation in the sky, by which I mean the banding isn't just at one or two tone level.

    Meanwhile, my recently acquired SD1M is back in the drawer, grrr!, and the trusty SD14 has returned to favor

    Sigma SD1M + 35mm DG HSM Art lens + 1/30 sec @ f /1.4


    Test for evaluating sharpness at f/1.4 on the foreground. This lens is incredible IMO. It was very windy, but the auto-focus held it's own!

    Shooting at the Sun
    Sigma SD1M + 70-300MM F/4-5.6 DG OS + 1/500 @ f/8


    I purchased this lens used and tried it out for the first time during this visit to Apalachee Bay. Not bad for the price ($100 after 20% off at KEH) as focus was accurate and color fringe is not bad. A good lens to take when I want to leave an expensive one behind.

    It's Complicated!
    Sigma SD1M + 70mm F/2.8 EX DG Macro + 1/200 @ f/2.8 @ 100 ISO

    Another test this time doing a walk-around handheld with the 70 macro. I will not be doing too much of this type of shooting as the SD1M is not your typical DSLR and IMO, works best on a tripod while waiting for the processing time to catch up. I generally shoot bracketed exposures in 2/3 stops and the processing time gets a bit annoying, but when the desired results are there, no other DSLR I have used comes close to the resolution, especially coming from an APS-C size sensor. This is a heavily cropped image that is about 1/4 of original size. The f/2.8 was not my desired f-stop, but due to ISO requirements it landed there. Focus was on the shadows of the pistols and the AF worked well.

    Re: SIGMA SD1 shots

    Trying out a new to me 50-500MM F/4-6.3 DG EX APO HSM at my local NWR. Unfortunately I forgot to do MLU while running through the f/stops because the bugs were biting and I wanted out of there ASAP. An alligator appeared after a few minutes and starred at me until I packed it up. These images are soft, but pushed to 800 ISO, and one shot at f/16.

    I feel confident the SD1 can handle 400 ISO and 800 ISO in an emergency. There is noticeable diffraction with this particular lens past f/11. The next day I ran tests in my backyard with MLU, and at f/5.6, f/8 and f/11 this lens is sharp.

    Old Gulf Station
    Sigma SD1M + 12-24mm F4.5-5.6 DG HSM II (16mm) + 1/40 @ f/11, ISO 100


    Here I am testing a used 12-24mm F4.5-5.6 DG HSM II after a copy of a 10-20mm F4-5.6 EX DC HSM fell short due to left side distortion. The 12-24mm performed well as long as I stay in the f/8 to f/16 range and be mindful of flare. I used artistic license to try and give an aged, but colorful presentation of the gas station. This lens is stellar sharp and I purposely added softness in post.

    Did you add a soft glow to this shot of the Cabin "Somewhere In Georgia" or is that out of the camera. It's pretty.

    Hi Robert,

    I think I may have added a sunlight filter (NIK software) via post, but it was that magical time of day about an hour or so before sunset. It was already "pretty light," but as I stood on the other side of the fence and close to the road, I watched the sun-glow arrive, and then leave about 10 minutes after shooting. It was a beautiful experience, the type that drives me to get out in the landscape just to see if it will happen again.

    Kind regards,
    Darr

    SIGMA SD1M and Infrared Photography

    The technical answer to your question for Darlene is "No".

    IR (infra-red) is beyond human vision - it can not be seen. If it can not be seen, it can not have any color. So the only true IR image is black&white (greyscale).

    But many IR shooters will apply false color to their images (there are many methods) to make them more interesting.

    Thank you Tam (and Ted).
    IR photography with the SD1M is black and white. The false-color Ted refers to cannot be obtained with the SD1M unless the user can manipulate it in via post-processing somehow. The false-color IR photography seen on the web was produced by cameras that probably were modified at the sensor level, which the Foveon cannot be (I inquired at LifePixel). If I wanted to go that route, I would send my Sony NEX-7 to http://www.lifepixel.com/ , but IR photography for me is all about black and white.

    BTW, your motorcycle photo is very stunning!

    Kind regards,
    Darr

    Re: SIGMA SD1 shots

    Thanks Ted and Darr for valued explanation. I am wondering if we use IR590 instead of IR720, SD1m will produce some yellow/blue color as bayer sensor?

    One more shot for Darr :-)

    Darr, please allow me to clarify some statements.

    IR photography with the SD1M is black and white.
    Even with an IR filter attached to the lens, all 3 layers respond, including the "blue" top layer. And the X3F file itself remains a 3-channel color image.

    Here is a raw histogram from a full-spectrum SD1M, shot with a Marumi 700nm on the lens.




    If the shot is opened with anything that converts the raw data to RGB, you get a horrible red image which is why many people immediately select monochrome mode. For example, in SPP, my shot opens like this:




    However, other converters are less severe, for example FastStone Viewer which puts up incorrect colors for normal Merrill images but does quite well with full-spectrum or IR-filtered shots:




    Some applications can create raw composite images; they take the raw data as-is, scale it to an 8-bit TIFF and apply gamma correction:




    Now the slight imbalance in the raw data is seen as a slight tint which could be further manipulated in post.

    Knowing that Darr prefers monochrome, that application can also export any one of the three Foveon layer channels. Here is the red channel followed by the blue channel:






    Both of those are as exported with no further processing. The red appears "better" to the eye but some say that the blue (top layer) gives sharper images.

    The false-color Ted refers to cannot be obtained with the SD1M unless the user can manipulate it in via post-processing somehow.
    All of the false-color images above came from a standard SD1M (dust-cover removed) with an IR filter on the lens. No post-processing at all except that I sharpened one of them. I've also had some fun by starting with a monochrome image then playing with individual RGB curves so that tint hues become dependent on pixel luminosity.

    As to the term "false color" itself, I suppose any color other than grayscale in an IR image is "false" but I notice that satellite IR views of the earth are often quite deliberately colored presumably for analytical purposes.

    The false-color IR photography seen on the web was produced by cameras that probably were modified at the sensor level, which the Foveon cannot be (I inquired at LifePixel).
    Darr, Is that the kind of modification where the Bayer-pattern CFA is permanently replaced by a single color filter?

    Tam, the lowest I have is 680nm. Your 590nm will allow visible wavelengths to reach the sensor - more so than your 720nm. To guess what would happen you need to see the manufacturer's data for the filter - specifically the spectral transmission curve.

    My guess is the image converted to RGB would still be dominantly red but with perhaps some yellow beginning to show if there is yellow-green in the scene. Just a guess. But you should be able to see through the view-finder to compose and the AF should be more reliable.

    You gotta love this thread. Do bayer-sensor camera owners have this kind of discussion?

    Ted,
    Yes, as far as I read over at lifepixel.com.

    Tam,
    Experiment and show us what you get, because I really do not know. I only use the Hoya IR720 because my objective is black & white, but I would be interested in seeing what you can produce with an IR590 filter.

    Kind regards,

    Re: SIGMA SD1 shots - some spider shots

    These are full-spectrum shots just for the hellofit.

    Thing is, when there's not much IR in the scene, colors can look almost normal.

    This one is busy wrapping up it's lunch for later on. Pardon the camera shake:



    This one seems to be busy on lunch. X3F opened in RawTherapee and the colors messed with unmercifully - and, yes, accidentally left the lens on max aperture (blush) but still, the meal came out pretty good. eh?



    munch, munch, much . . . .

    Re: SIGMA SD1 shots

    Hi Ted

    I guess I was thinking that if I wanted to expand into more Foveon beyond my DP2M and had decided that Quattro was not my bag, then the next obvious choice is SD1M or SD15, I guess. The trouble is that, whilst it would be nice to have a proper viewfinder with Foveon, this path leads to increased weight, less ability to hand hold because of SLR mirror and the quagmire of having to choose the 'right' lenses again. Not to mention probably battling with front/back focus issues. So my thoughts drifted to the SD1M and some 'reasonably' priced walk-around lens. And then maybe expand into the 'Art' lenses at a later date. Again, more expense and weight and not necessarily that the results would be 'better' than I get from the DP2M.

    What I *really* want is a Merrill sensor inside a Fuji X100T body, complete with conversion lenses.

    LOL

    Hmm, quite a lot to consider! I do have an SD1M with a 17-50mm on it. Less than 300 shots on it. The 17-50mm shoots well for my purposes and is a constant f/2.8 as you know. But lately, I've been picking up the SD14 again, because of it's smaller X3F files.

    As to the DP2M, I've had one and, as everybody says, it would likely give you slightly "better" images in the right conditions. Sold mine long ago but not for reasons of IQ - more for it's handling and super-slow SPP 5.5.3 on my XP Windows machine.

    I, too, am thinking about the 18-35mm Art . . .

    Hello Lee,

    I understand your problem. I used extensively those DSLR and sold it because I was not able, finance wise, to sustain two "very different" dslr systems into my company. I had the SD1 with some very nice lenses (and the SD15 too). Having an OVF with foveon is a dream but this dream come at a price : It is true hazard to have DP quality with an SD camera, whatever money you churn out, whatever lens you buy. It is less an hazard today with the Art lenses (but it cost...).

    Wife discovering that her shoot is blurred even with stabilisation...



    The thing is that SIGMA spoil ppl with the DP. You taste the DP sharpness and you are very disappointed when you jump on a SD, even if it cost FAR more money. This is a kind of paradox inside a brand... and odd one per say.

    The first lens I tested on the SD1 was my 17-50f2.8 EX... was working perfect on the SD15... completely out on the SD1 >> disappointment.

    Then came all the good primes :

    50f2.8 >> OK.
    50f1.4 EX>> not very OK, inconsistent, almost a fail with AF especially close to f2/f1.4.
    85f1.4 EX>> not very OK, inconsistent, almost a fail with AF especially close to f2/f1.4.
    150 macro EX >> almost OK. Very good when spot on but sometime not consistent for whatever mystery reasons.
    the zooms seems to be more consistent than the primes if you have a very correct copy.

    Roughly, the SIGMA AF sucks big time.

    And no, this kind of AF behaviour is extremely rare on my Nikon system. Focus perfect at f1.4 with whatever f1.4 lens used.

    So what to do ? What to choose ?

    My opinion is you should wait. I understand why Quattro isn't your cup of tea. I hope big time that Sigma understood it too. I do not know what will announce SIGMA next year. We might have a teaser before the end of the year but...I wouldn't expect that much. The best AF with foveon is contrast AF... It would be good to have a DP with stabilised zoom and EVF... or maybe they will stop producing cameras.

    Just wait. At the end you'll be able to buy tones of old sigma gear at mini price on internet.

    If their next DSLR is a quattro APS-C DSLR, the SIGMA balloon will flatten very quickly. They do not have the technology to make a superb AF. They must be very imaginative and they must take BIG risks, otherwise it will be just mad to sustain an almost non-existent niche market. Pentax is coming with something very good and even the price will be very good. Foveon or not, it will be hard to compete.

    The SIGMA camera niche market already started to vanish since Quattro debacle. Hopefully they have the ART lenses line. BUT you can see TAMRON reacting very hard too so... very interesting and competitive time ahead


    IMHO, Sigma should have taken big risks sooner. They should have build a 24x36 prototype aiming landscape photographers or artists in a market section like ALPA or any view camera company with very competitive prices and ofc, the true foveon. Not that much sales, tiny niche market, but I think at the end it would have been stable for them. Many Lula members would use it and praise it instead of mocking it on public videos. HERE

    They should have taken big risks sooner, just following the Merrill success (at least internet success which is somehow a very good thing by today standards). Thing is they didn't did it at all and I have big time understanding why. They had a golden window and decided to ignore it for whatever reason... thus my complete frustration as a former ultra fan of the brand.

    Now, trust me, they are not in a good position with this Quattro especially compared to Merrill. It is why they need to backPedal big time and bounce on whatever idea to hook again the swag.

    Hi Hulyss

    Thanks for your lengthy reply. I think I had already decided and your reply just reinforces that feeling that 'life is just too short' for all this messing about, especially when the gains are minimal. A year ago I had all three DP Merrills but realised I wasn't using the '1' and the '3' very much, so sold them on to concentrate on adding to my Fuji kit. I regret that to a degree and may end up buying one or both back again (maybe) but I think that, after my recent foray again into the Foveon world, I realise that my DP2M is probably enough for now and that my Fuji gear can co-exist quite nicely with it. At least that's how I feel today ...

    Yea, photography market is pretty boring actually. When new "cool" things hit the market at 3500 without lens, it is what I call a non excitement I hope that next year we will see some move and will have all more fun. It seems to be common to all brands actually.
