How bad is it for the lens if your lens cap comes off inside bag?

I have Tara cables and interconnects in one of my home systems as well, (not in my main sound room though. Pretty much every room in my house has some sort of music system. As you are probably aware, even at $150 a foot, which would be considered over the top for wiring to most people here, your Tara wire is downright inexpensive in the world of high end audio. You can easily spend $750 to $1000 a foot!

My uncle has used 50,000 dollar interconnects.... He does admit cables sound different.... typically the more expensive they are the junkier they sound. It's all about minimizing dielectrics is the key to great sound and stick to pure copper for better sonics.

Here is his $300k system

Yeah, they aren't much in the audiophile world... $150/ft is what I remember telling wife; I'm just guessing. RSC Gen 2 reference. My comment was relating the monster cable vs UV filters. Tiffan might be Monster Cable of filters. Glad to hear of another economic Tara owner.

The speakers look like an old pair of Apogees. I love the baskets an cynderblocks on the floor for diffraction.

Yup, apogee duetta signature IIs.

I still think it's crazy he sold a 1971 Boss 351 mustang for 40k so he could buy a $35k turntable from Basis audio.

Please tell me that those pipes on top of the power amps are some sort of forced air cooling system. That room is just nuts. I'm reminded of the mock home style magazine in episode of Father Ted that had "Brick enliven's dull floor" on the cover.

Looks like the subwoofers have undermined the foundation?

I'm not a fan of protective filters but for those who are, and who are reading the lenstip review cited in this thread, it's worth bearing in mind that that review is rating primarily on UV filtering performance, something not important with digital sensors. The reviewer notes that:
"We were also surprised with the low 8th position of the WPC coatings used by the top model Marumi filter. Although this filter has the highest light transmission in the visible range and has a very small tendency for flares, it only barely blocks the UV radiation, which should be its primary function after all. Why would we need a UV filter which cuts out the same amount of UV radiation as a regular glass? However this filter can be useful for people who want to protect their lens from the outer factors. Thanks to its visible range features, it will pass this part of the exam perfectly."
So top-level Marumis might be good value as protectors since they are relatively cheap (compared to, say, B+W). A review that tests glass and coating toughness and scratch resistance would be useful but I haven't seen one anywhere.

LOL Those are not pipes. They are the tops of the amplifier Vacuum tubes, or valves as they are known to our British and Canadian friends. These are tube amplifiers, not transistor. Any additional cooling would be provided by whisper fans. Tube amplifiers generally are exposed to allow the better dissipation of heat. While I and many others go to great lengths to set up a system to "play the room" this setup seems way over the top to me, but then I've never heard it, and in the end the sound is all that counts. The Apogee duetta signature IIs. speakers are a thin panel only a few inches deep with a ribbon mid range and tweeter and bipolar quasi ribbon planar bass panel. They need a lot of air and space around them to do their magic and I fear that may be somewhat impeded by the presence of so much gear and equipment in front of, and behind the plane of the speakers. The various bricks, baskets and sound material on the floor, ceiling and walls is intended for diffraction and absorption to, among other things, break up lower frequency standing waves.. Effectively it maximizes the speakers ability to deliver the pure bass the speakers are capable of by eliminating the effect of the room. In the end a properly set up and amplified pair of these speakers will generate the illusion of a huge sound stage that extends well beyond the side and front walls, and both the walls and speakers will disappear. The instruments will be placed in this sound stage as they would be in a live venue. It is not only a startling illusion, but with great recordings it can be a an extremely stirring emotional experience. Now, after that digression, back to photography.

Ah I see.

What about this one:

(Full image, not 100% crop)

Are those flares on the traffic lights due to the UV filter?

The halos around the lights are not due to the filter. Filters cause ghosting by reflecting bright spots on the sensor back out to the filter, and then from the filter back to the sensor. The result is a ghost image on the opposite side of the image. The ghost image is quite a bit dimmer (fortunately) than the source light because of the losses through the system and because the filter only reflects a small portion of the light. The better the coating on the filter, the less the reflection.

There is nothing new about this. The ghosting phenomenon has been known for decades.

In this picture, I see at least two spots that are likely ghosts. They are the green spot just below and to the right of the roughly central red light, and the small bluish-white blob below that green spot. The origin of the white ghost is the bright white light just left of the center of the image. The green ghost origin is the small intense white light with a green rim sitting on a bluish column. It is just below the white origin.

You can see that the origins and ghosts are opposite each other from the center of the picture.

Just to be sure, we can measure the locations. This photo as posted has dimensions of 800x533. So the center is at x=400 and y=266.5, which we will abbreviate as 400, 266.5.

That bright white origin is at approx 331, 274. Its ghost would be expected on the other side of the center, at 469, 259 (calculated from 800-331=469 and 533-274=259). The measured location is 472, 264 which is pretty close.

The green origin is at (approx) 339, 341. Its ghost should be at 461, 192. The actual location is 466, 185, again close enough, I think.

The red light (at 434, 155) also seems to be making a faint ghost (at 369, 382).

There are a couple of bright lights on the traffic light pole. They would make ghosts in the one-way sign where they can't easily be seen.

In short, I'm pretty sure there is ghosting going on in this picture. It could be demonstrated easily by taking the shot again without the filter. Not a big deal - such ghosting has been shown many times before by others.

Wow, B&W filter and Monster cables

Monster cable didn't win the competition, however.

So nobody willing to try the postit note challenge? In fact, cut out a strip about 1-2mm and attach it to your lens, then take a shot. It is interesting to see what impacts you see in different lighting situations and different apertures, but generally speaking, you won't notice it.

It's supposed to screw up the bokeh.

He has some fans mounted in another room that suck the air out of his amps. Those Audio Research Ref-600 monoblocks and he can only use them in the winter since they heat the room up too fast. In the summer he simply cannot run them so if you notice behind the mains to the outside are the Krell monoblocks the FPB-350Ms that he uses during the summer.

So yes... the pipes above the amps are designed to "help" suck out the hot air the amps create and he dumps it into the adjacent room where he has a return air at for the A/C.

No subwoofers in his system. Just the speakers. Which are you referring to?
