Well I was expecting a wait(based on experience). And so I won't bother saying how anxious I am to see how the SD1 measures-up against the competition(is there any?).

And so I'll just go ahead and say for the record that as a Pentax shooter, I'm rooting for Sigma this year!

My drug of choice is landscape and if the SD1 turns out anything near the 645D at under 2K then I'm clearing my bag and taking a residence with Sigma. Even if that means sacrificing high ISO and high FPS to get it! - Which only goes to show just how important resolution and color truly is in certain cases.

And though it may a little late to say it, I'll just say as a final plea, I'll just leave it at; "please don't make this another over promised, under-delivered product" :)
 
I think it will come a lot closer to the 5D II than the 645D, at least in terms of resolution, especially since the 645D doesn't have a resolution lowering AA filter. Based on my own comparison with the SD14 vs the 10mp K200D (virtually no difference in resolution) I'd expect it to be the equivalent of a 25-30 MP Bayer sensor with an AA filter.
 
Depends on what we are measuring.

Spatial resolution? Color resolution? Perceived sharpness, acutance, micro contrast, pixel sharpness, accuracy, so many different factors that contribute to the final 'image feel'.

Spatial resolution of the SD1 will be similar to the 5D2 (because the canon has an AA filter even though it has a higher spatial MP count). However, it will still be less than the 645D.

BUT...

The SD1 colour resolution will be higher than BOTH the 5D2 and the 645D, which means that the feel of the image will be different.

Possibly even better in some respects, because the sensor architecture and read noise has been dramatically improved on the per-pixel level, but we shall see.

Most interesting!

Then again... I've always considered the K200D was somewhat of a boon as it rivaled the 14MP K20D also. However, on the flip-side, the K-5 seemed to pickup where the K200D left off in terms of resolution and so I'm hoping the SD1 could follow suite?

Ans so my question is how well the native 15MP sensors can compete with that of Sony's latest sensor? and my hope is that if its even close, it might just end-up at an advantage in a 3x configuration(I hope).

Anyways, I know its all just wishful thinking at this stage, but... I still hope the SD1 can pull a rabbit out of its hat this round.

PS. what about the D3x? How close would you expect the SD1 to come to the D3x in terms of final resolution?
 
I think it will look better than D3x in general, even though D3x has higher spatial resolution.

However, I think it's pretty pointless to play guessing games at this point. Better to just wait for the SD1 to be released and look at real-world examples of 15x3 new-architecture Foveon MP in the field!
 
In my opinion the biggest factor will be the quality of the glass. You'll pretty much need a Pro Grade lens to even compete against even a 20 year old Med Format prime.

But then again, the same even went with my old 6mp Pentax K100D. You could really see the Image Quality difference between the 18 - 55mm kit lens and some of my older primes. Even though the 18 - 55 is no slouch.
This difference will be magnified on the SD1.

totally. Sigma's best lens is the 85mm 1.4, which is one of the sharpest ever from any manufacturer outside of medium format.

the 50mm 1.4 is good too, as is the 17-50 EX OS zoom... but they need some more top quality lenses in their lineup no doubt!

might be time to start doing lens conversions...

What do they have on the wide end of things?

I typically shoot in the 35mm range for most scenery's and I've already looked into modifying my favorite Pentax lens(K 35mm 3.5) for the Sigma mount. But I'd rather not have to do that if at all possible.

That's one place where Sigma still seems to be lacking, although I've heard several people swear by their 30mm F1.4 EX DC HSM.... and others swear at it.

I think that it's one of those lenses that may need tweaking to the body, which we'll finally be able to do with the SD1

Well, if you are a Pentax user you probably subscribe to the philosophy that 'primes are life', but the 8-16 zoom in the Sigma range is unique and very high quality (assuming you find one that’s not de-centered that is)

do you mean the new 8-16mm ... or one of the 10-20mm 's?? there's also a discontinued (I think) 12-24mm (all Sigma lenses)

Damn... your right... its the 8-16... the mm of my Olympus lens popped into my head as I wrote it.

I think I could live with 30mm :)

However, that would likely be my limit, as I prefer to steer clear of the distortions that come at/or around the wider end of the curve.

Having said that, I'm fully prepared to mod a K35/3,5 for the Sigma mount, if the camera lives-up to its potential. And I'd have no problems mounting and leaving it on for the life of the camera. (its just that good :p)

My plan is to dedicate a body for landscape and leave it at that.

Does anyone know if there have been any full size samples of the SD1 published yet?
I know there were prints at some point, but has anyone seen an actual file yet?

Hey ya JB... :D

Nice to know I'm not the only "one of us" rooting for this SD1 beastie!! I was really impressed with the feature list in that video from, oh heck I forget the show last winter. But after looking at the shots people are posing from their other Sigma bodies I am really loving the design.

I also looked at this as a viable 645D option. Even more so now that I picked up a real paying gig for photography (completely out of the blue and unsolicited by me...color me skeered on that front!! hahaha) but it will pay for an SD1 or a 645D so I dunnoooo...

The only thing I would really need is tethering. Again nobody knows so far but if history is an indicator it would seem no on tethering with the SD1. Then again HoyaTax hasn't pushed tethering out the door for the 645D/K5 either and they sort of promised it...sigh, I don't wanna go back to Canon. Really I don't wanna!!

I think you might be generalizing juuuuuust a bit too much. ;) I value the higher end primes and have a number of them, but also there are several great zooms in the DA* lineup as well as the older FA* glass. What has been the bug bear in people investing in the Pentax zooms was the problematic SDM AF setup. Luckily it seems that issue has either settled down or if unlucky it's just because people have really stopped buying them out of concern that 18-months down the line the SDM sill fail. With the new 40% to 150% higher prices on all their glass, Pentax users are looking at other solutions, something pretty rare in the past.

Right now the new Sigma sealed glass is getting a fair amount of attention from many Pentax shooters like myself and others...but then again I have long enjoyed shooting Sigma glass. Miss my 10-20/4-5.6 and Bigmos and worst of all my 24-60/2.8 which is one of my all time favs!!

So ya found at least one Pentax folk who loves Sigma and zooms as well. :D

http://www.x3magazine.com/2011/02/17/a-wealth-of-sigma-sd1-info/

Bob Van Ooik, a well-respected Sigma photographer on these forums, on his X3 Magazine site said there were rumblings he heard about Sigma developing tethering software for the SD1.

It's not a deal-breaker for me, but I would love to have tethering with the SD1.

Make that three of us...it's a regular PentaxForums reunion. ;)

Actually I'm interested to see if the mirror box on the SD1 can be modified to allow Pentax lenses with no modification. My dream is to have a K5 for high ISO and an SD1 for amazing color/detail work (with the same lenses on both). :)

A recent Pentax user modded out a FF Canon DSLR to remove the need of clipping the aperture level on his lenses. If the same can be done to the SD1... ;)

Anyway, I too am rooting for Sigma. I just couldn't justify the switch with the SD14, but I'm hoping the SD1 will be the camera that starts the "revolution" as their marketing states. I can't help but follow rytterfalk's blog and this forum, something about that Foveon sensor really sparkles!

One more Pentax user to join your thread - me :)
I share your reasoning and hopes regarding the SD1.

There are several things that might make or break my move to the Sigma system:
  • The shot to shot speed that the SD1 will have - I am ready to wait as I am no sports/fast action photographer, but still there are certain limits to what is acceptable - some 10 and more seconds shot to shot speed in RAW mode will really be painfully long in comparison with today's standards.
  • The IR filter - (I can easily live with high ISO performance that is worse than the current Bayer leaders) but it will be outrageous if they haven't solved the issue of the IR filter making the shadows in underexposed shots greenish - this is not the price category in which one will spent 5 extra minutes to solve hardware introduced image problems in many shots.
  • The focusing speed and accuracy - it is nice that the Sigma SD1 will have a focus adjustment on per lens basis and I don't really need to better the USM in terms of speed, but again focusing accuracy and speed are poor with the current Sigma DSLRs. Lets hope the new focusing system was developed by the R&D department and not the marketing department of Sigma.
  • Lack of live view really means that I would need the option to be able to change the focusing screen - I am really sensitive regarding the spot on focus and having tons of fast old M42 and K-mount glass I will really not go for the SD1 if it has no way to properly focus these.
If any of you can answer regarding some of my concerns I will really appreciate it!

I would really love to go for the SD1 and I hope I will go for it as I believe that it should have these issues solved.

Have a great day/evening!
Yanko
