And are they removable or can they be bypassed? The original premise (i.e. shooting infrared) is still very intriguing!< They are physical, and are mounted in the optical path behind the lens. They are not therefore easily removed. The 3 colour splitter prisms will also remove most of the Infrared spectrum. As I've said before, you can get cheap CCD surveillance cameras that are open to Infrared. You do not need colour, and infrared resolution is poor, so the single chip cameras work fine. It is best to remember that the visible spectrum is a very small portion of the whole EM bandwidth. 'Infrared' covers everything from near visible to simple radiated heat. There are some very exotic products needed and available to 'see' the longest wavelengths but CCD chips have a good response (normally not wanted) to the near visible.

Perry Mitchell Video Facilities http://www.perrybits.co.uk/ Problem with VX1000 - "Perry" From: david THOMAS: I've got a slightly unusual problem with a VX1000 I've just acquired. Camera is perfect in every respect except that the production company I bought it from had fitted a step up ring to fit the wide angle lens they also supplied with it. Problem is the step up ring is completely frozen onto the lens thread which is stopping me from fitting a UV filter to protect the front element. I suspect the adaptor was fitted when they acquired the camera about eighteen months ago and never removed since. Any ideas? I don't really want to drag it back to the vendors as that would take a good half day out of my schedule. I obviously don't want to risk damaging the lens assembly and I would prefer to keep the step up ring intact though not permanently in place.

Reporter/Producer Needs Help - "Perry" Keeping up with new technology is not quite as big a problem as some have surmised! My 10 year old BVW-300 still makes good pictures and I can still happily use the BetacamSP tapes within new technology. I've tested the PD150 and VX2000 against my VX1000, and for most situations the differences are negligible. The real deal with new technology is that it gets cheaper and cheaper for the same or better quality. The VX2000 is half the price (allowing for inflation) of the VX1000. The GY-DV700 camera I'm testing sells for a fraction of what my BVW-300 cost. All this changes the marketplace; kids straight out of college can afford a broadcast shooting kit and this drives down the hire price. You can now do Avid quality editing on a rig that costs less than 10% of a 'real' Avid. The UK market is awash with kit and operators trying to make a name and reputation. Mostly this involves doing jobs for expenses only or at best deferred payments. Presumably talent will out but I'm glad I'm near the end of my career and not just starting out!

Perry Mitchell Video Facilities http://www.perrybits.co.uk/ Sony Web Sites - "Perry" Robert's query about the DSR-20 prompted me to say that I recently compiled the following list for a UK magazine. Perhaps it will be of interest. (beware of any URLs that word wrap!) Sony is actually a web of different companies that often host their own Web Site and have very different policies as to how they release information to the public, i.e. you and me. Here is a list of the global sites: http://www.world.sony.com/CorporateInfo/GlobalSites/ If you are trying to get information about a new product, you have to be prepared to trawl around. Often the very first pictures of a hot new product will arrive on the companies corporate Site in Japan: http://www.sony.co.jp/sd/CorporateCruise/Press/ This is in Japanese but the product names are often in English. There is a domestic Japanese marketing site called Sony Drive: http://www.sony.co.jp/sd/index.html This is interesting to see what all the latest gizmos are. There is an English section intended for tourists: http://www.sony.co.jp/sd/ProductsPark/Consumer/Tourist/index.html The entries are refreshingly free of marketing BS, and include comprehensive specifications. Checkout for instance: http://www.sony.co.jp/sd/ProductsPark/Consumer/Tourist/DCR-VX2000/index.html Eventually you’ll need to come closer to home. Sony Europe has a central Web Site: http://www.sony-europe.com/mcp/mahir.x This is intended for consumers but I find it all mouth and no trousers, or typically lots of flash graphics and little real information! Even closer: http://www.sony.co.uk/ We still have a site that is almost impossible to find what YOU want to know rather than what THEY want to tell you! Fortunately English is a pretty common language, so we can troll further afield. Australia is not only English speaking but also has PAL television. Their site: http://www.sony.com.au/home.asp is both easy to navigate and full of good information. It also refreshingly has the whole range of products from consumer to broadcast on the one site. Sony Canada is similar: http://www.sony.ca/ They are of course NTSC so you have to be careful with the information, but Sony Canada put the corporate brochures on line in pdf format which can be handy since they usually include information on the PAL version. They also have a special DVCAM site, so you can see both together here: http://www.sony.ca/dvcam/brochures.htm Back home, Sony Europe have a specialist Broadcast and Professional division with their own web site: http://www.pro.sony-europe.com/ where you will also find some ‘Micro-Sites’ and also a site for ‘new media’: http://www.sonynewmedia.com/ The professional sites are certainly easier to find information, but I find it is not kept fully up to date. And so let us finish by going over to the ‘Big Daddy’ at SEL (Sony Electronics Ltd) which is Sony A/V products in USA. There are also a mass of connected sites, the main site is at: http://www.sel.sony.com/ with a nice powerful search engine right up on the front page. This links right through all the product ranges so you may well find yourself directed to the professional site at: http://bpgprod.sel.sony.com/home.bpg with an even more helpful search feature. Good hunting!
