Here are some photos of the new Isco IIIS. Little brother to the III. I took some photos of them side by side for refrence. Same internal construction as the III, only smaller. Smaller means it is targeted at long throws and/or smaller panel sizes. III is still king, but this will be a new option with the same performance for those who don't need, or want the III. Will be less expensive however I don't have any MSRP info at this time. I believe this one is the first non-OEM piece in country. I expect them to be hard to get. Even this one is a loaner. Figured some of you would like to see it:

Alan: if the web address in the photos gives anyone heartburn, let me know and I'll remove the photos (or you will ). It's not there to advertise, I don't have any of these for sale. It's more for photo copyright.









I dont' have much other info to share right now. Excuse the rough photos.

Also, that is a (partially assembled) new Isco Multistand II on my padded table beside the lenses. I like it much, much better than the old stand. You can adjsut height and tilt independently. And it looks much better IMO.

Only in size. The Isco II had a different internal construction and some problems associated with that optical design as compared to the III. My understanding is it had 2 cylindrical and 2 spherical elements where the III and now IIIS both have 4 cylindrical elements. So my understanding from Isco is this one ought to perform just like the III, for projectors whose beam can fit through it. Much better than the II.

It's much smaller, but, it appears to be substantially larger than Schneider's CineDigitar.

Granted...I am sure it is a great improvement over the II. My point was mainly to say that they are now filling the price point level of the II. Not everyone can afford a III and the II used to fill a niche.

Nice one Scott. I'll hold onto my ISCO III all the same. Even though I still don't have a projector for it

At my shop I have a demo C3X720 I'm using to make an integrated CineSlide mount for Sim2. I held the III-S up in front of it last night. With the C3X zoomed out, to my surprise, the beam fit through it with apparent room to spare. It had plenty of clearance on the exit, it was tightest on the entrance/back side. But with that very rough test, I didn't see any vignetting at the long throw. I don't know what lens is in that PJ though. Surely the T2.

I had the feeling that the ISCO III-S is still a lot more expensive than the ISCO II was. Is that what you heard too?

Not sure...Scott can chime in on price, but the ISCO II was $2999 before is went away. The III is about $5500, so I cannot imagine the gap would be narrowed much more...

Best pricing is tightly tied to (large) order quantities. And the exchange rate (about 1.5 USD to the Euro today) has a huge effect on them, too. The II sales were before my time but I *think* the price Jason mentioned will be in the ballpark, maybe plus a little. I'd speculate it will run around a couple grand less than a III. I'll probably have some real pricing info in the next few weeks.

A rathwe colorful forum member told me that when he opened the box and grabbed the ISCO III and began to pull it out just the look ,feel and weight he immediately got a hard on ! I can't help but start to make comparisons between those two after that mental image.

This one's more sensous. You have to hold, twist and feel the action on this one. All the movement is on the inside here. Easier to lift, but that can be a good thing. Subtle, sublime, mmmmm.

I'm sure it is a heck of a lot easier to secure onto a ceiling! Man the Cineslide/ISCO III combo is HEAVY!

Different length = different focal lengths on the lenses, so it's not exactly the "same internal construction", more like same internal design strategy... but I see what you mean Scott.

Any chance of placing some recognizable object (like a ruler) next to it so we can get an idea of scale, please?

Thanks...

Yes, that's what I meant of course.

What that 13mm socket wrench laying on it's side wasn't enough?

Surprised it took this long for someone to ask. I meant to originally and just forgot to get back to it. Was too lazy at that moment to go shoot/load/photoshop/scale/etc... But sure, I will be happy to get a size reference in a photo.

AB, I thought you'd be interested in this design detail. Like the III, the IIIS exit element does move in relation to the entrance element (excuse my less than technical terms) when focusing. A cosmetic difference is that the external body length does not change. Also, the IIIS has a lock thumb screw on the side (not pictued).

I haven't had this one (mounted) in front of a PJ to see any screen effects.

One other detail for those not familiar with the III. The larger III in the photos above has it's focus ring adjusted so it is extended out a good bit. The III gets shorter/longer as you adjust that ring. You can see if you look close that it would not be much taller/longer than the III-S if it were adjusted at it's mimimum length. But each individual installation dictates that position, and thus length. The III-S body length does not change, that movement happens inside the case.

Jealous. When you're making a one-off (as I did) throwaway phrases like that cost $Thousands to turn into reality the first time.

I thought it was 12mm. Those babies are bigger than I thought!

In lieu of photos, some dimensions would be great (if you still have the lens, that is).

As requested.... Obviously these aren't catalog quality shots, excuse please. I don't have a ruler handy that doesn't cause my exposure to be off. So I fiddled with the shots ehough so you can see the tick marks and the lens. The DVD is pretty clear though. S













While I'm at it, the new Multistand II:

THT?

Welcome, I took some shots of the entrance side but they didn't come out. I'll try to take time to try harder before I send it back.

We have had our III-S for a while now and very impressive it is too!

Coule of points though - over here in Europe that is the only Multistand that we have ever sold with ISCO lenses, did you guys have something else to work with?

The III-S is really a lot smaller which means that throw and panel size are much more important issues. Scott states he hasn't seen an issue with the C3X but I am a little surpised by that. With the Titan we felt that a throw of around 2 was needed (with the 1.8-2.6 lens for reference) to have no noticeable aberations. Like Scott's our lens was also not classed as final production but would be very surprised if there were any performance changes between these and the shipping product.

In terms of cost, in Europe the III-S is about 25% less than the III-L but still a fair bit more than the II was. You must remember that the III-S is a much improved and more complex piece of optics though.

Yes until recently we only had the Iscostat-9 available in the US for non-OEM. The Iscostat-9 was the older stand with the Bosch square posts. And until recently you would have had the multistand-II similar Multistand-I. At my request Isco redesigned the Multistand-I to be compatible with the CineSlide. The "I" isn't compatible. Isco just finished those chages a few weeks ago. While similar at a glance, the Multistand-II has several changes compared to the "I". The are easy to tell apart, the post sliders sit rearward of the lens on the Multistand I and they sit closer to center (40mm offset from rear) on the Multistand II. The specific lens adapter ring enters from the rear on the multistand II. And the Multistand II has a set screw to prevent lens rotation. The multistand II mount plate is thicker, and uses larger (M4 hex socket vs M3 flat head) set screws for holding the lens adapter ring.

Yes. In case I forgot to say, it only worked with the sample C3X I had with the zoom at max/long/narrow. But I was surprised it fit even then. The sample C3X probably has a T2 lens so a throw of well over 2.0 (maybe 2.7) where I did the rough check. This was unmounted so I can't assure anyone it would work witha C3X, yet .

Update:

Now this is something I DID NOT expect. I took a C3X(720) and tested it with the new lens. Lens mounted and projecting ona 51" tall screen. What I found was indeed surprising. This lens worked comfortably from a throw of 1.6 to 2. It may hav gone a little lower but I didn't want to push it. This on a case that has a recessed lens.

I don't know how much larger the light beam is on a C3X 1080, but the panel size is larger IIRC, right?

What's the diameter of the rear element? Looks like around 70mm.

Really? It must be a good amount larger aperature than the II. I use an HT380 at about 1.55x and the ISCO II I tried didn't work (caused too much vignetting).
