Post your foveon DP & SD1m Images

Keith

I still use the dp2m much more of all the Sigma cameras I own. The 45 pov works for me. I tend to use the sd1m for situations where I know the zoom will come in handy and/or I need tele/macro work.

The af speed is slower than I would like. I think part of the problem is the sigma slr lenses are huge (more mass to move). It is not as fast as my Nikon dslr. The 30f1.4 is the next fixed lens I am planning to pick up (just waiting for sale). It is quite a bit smaller compared to the 50f1.4 I have.

Eric mentioned he uses his sd1m more than the dp2m he has. For now I like the dp series more, but that could change after I get the 30. The dp series in terms is limited to focal lengths. I tend to shoot a lot of different stuff, which is why I always had a dslr around. The Nikon dslr even though af speed is faster, is collecting major dust. Between using the Fuji and Sigma, not seeing much love.

I forgot to mention... I wish the sd1m had live view..wishes for a next gen cameras
- live view, faster af, better CPU and more buffer for sd1 series
- a csc version that uses the lenses sigma made for the Sony Nex line
- a dp that has a retractable lens and smaller overall size like the Ricoh gr

Btw I recently stumbled on this sigma propaganda where they loaned this guy some lenses. Turns out the 24-70 was one of his favorite lenses.

Sigma DP2M versus RX-1

Sigma DP2M versus RX-1

All

I don't know the value of this but it may be of interest to some of you.

I own both the DP2M and the RX-1. In fact I also own a DP3M as well. I appreciate I am lucky to own all three cameras.

I have recently returned from 4 days photographing around the Somme in France. Pretty grim topic and not my first choice but I agreed to accompany a family member.

I am now processing the pictures and by chance I have a comparison shot between the DP2M and the RX-1. I have noticed some chatter here at RFF about both cameras. This comparison pretty much summarises what I think of the two cameras.

Both shots were at f8 focussed on the foreground. The only difference is that I had left the RX-1 on iso640 whereas the DP2M was shot at iso100. It was a hot muggy day with a weird hazy overcast through which the strong light was somewhat diffused. This lead to almost no definition in the sky.

First up is the RX-1 shot of remembrance wreathes looking over the Somme plains at La Boiselle. I'd left the camera on iso640 by mistake.

I really like the colour rendition of the RX-1. Very film like. You have to be careful when converting to sRGB for the web that the colours do not oversaturate and I normally reduce before posting. By reducing the exposure in PP it has revealed that the sensor has captured some delicate detail in the sky.

Next up is the Sigma DP2M shot.

Not suprisingly the DP2M has to my mind bags more definition that the RX-1, although it has a more subdued character as far as the colours are concerned. Sky definition is not as good as the RX-1.

Although it is horses for courses my feelings between the two cameras are as follows.

The RX-1 renders much more artistically than the DP2M. It suggests to me that the Sony developers think much more about the look and feel of what comes off the sensor rather than pure IQ. The DP2M shot is characteristically outstanding as far as IQ goes. You can clearly see that the green wheat crop is single stalks and even in the distance there is tons of definition. Quite amazing, really, for a compact camera (although we all know it is really more like a shrunk-down H4D!).

If I was exhibiting I would be tempted to go with the lesser definition of the Sony shot. I think a general audience would find it more appealing. However it is the DP2M shot which has ended up in my Flickr stream.

I appreciate that on the web at this size comparisons can be silly but the point here is the subjective view of this kind of picture, in a web situation.

What do you think? I'd be interested to know.

Because I'm horribly biased I'd instintively go with the Sigma shot .. to me the RX-1 image looks decidedly murky and the reds look a bit funky.

Both shots indicate that digital sensors really don't like reds ... my D700 is certainly no exception!
 
Though when it comes to images I find the foevon output really encourages me to experiment with my post processing ... which may be a sacrilige to some! :D

Both too saturated for my taste but if I had to pick one it would be the Sigma.
The green is more to my taste on the Sigma shot.
I own neither , I have a grd 4 and find the colour on that too strong.

So ,just me. :)
 
I prefer the green of the Sigma, but prefer red of the Sony, the Sigma is a little magenta, which I find typical of the Foveon sensor.
But in summary, both are outstanding.

It's not just you ... I find the same thing. The photography world has never recovered from kodachrome! :p
 
Keith, Michael, Mugent

Thanks for your comments. Very useful. You often need an independent voice to help you see something if you have stared at it for too long.

Keith, BTW that is an outstanding portrait. I would have thought that a film frame, possibly a summicron 35 and tri-x!

If someone can explain to me how when converting from Adobe RGB to sRGB you can prevent colours from oversaturating I would be very welcome. It seems to be the bane of my life. Am I missing something?

Thanks again

Helen,

It looks like u are starting to get comfortable w/ the dp2s. Do u still have the Merrill?

U removed your self portrait.. It was a nice shot of u.

Inspiring image quality. So I dedusted an old DP-1s I had lying around in the proverbial cupboard. The image was converted with ufraw. I find it is a quite honest and simple raw developer. The colors for DP-1s are a bit off sometimes, but I rather see it as a feature. ;-) A bit unsharp masking applied plus sharpening from flickr.

Another from my recent trip to Pas de Calais, near Arras. This is Owl Trench Cemetary on a backroad near Puiseux.

DP3M

and this is what we discovered when we went for a walk around the outside wall of the cemetary

Hmm, just came back from a little walk with the DP2s, a tripod and a flash unit. This sensor surely needs a lot of light and a tripod does not hurt. The view camera approach people are talking about makes sense. A shift lens would be great, what do you think?

But on the other hand, it should also work for "street photography", shouldn't it? Especially with prefocussing and an off camera flash plus viewfinder, aka flash and trash method.

I hear the shutter lag of the merrills is pretty short when prefocussed?
 
Just got some stuff in the mail for my DPMs. A couple of Flipbac grips and the genuine finder for the DP2M and a Viogtlander finder for the DP3M (thanks Stephen).

Had an interesting reaction to the black and white output of the Sigma the other day. A friend wants me to take some photos of his public art installation and I asked if he wanted it in black and white film as I usually do it. He's asked me to use the DPMs as he's really impressed with the monochrome from the cameras that he's seen so far.
