it looks more like a plastic, so that will light up itself, unlike paper...

After closer inspection I do agree.  This prompts me with another idea.  I've got some clear Remo drum heads and white painted over clear drum heads that I should test out...hmm..ideas can be endless

Re:  Calix

Nice job on diffusing the light which can be a big issue especially with insects such as Beetles with hard shells as their reflective properties can be troublesome.

I am amazed that the pop up flash (are you using FEC?) can actually burst light through that paper dish or perhaps I am misunderstanding how you have diffused and softened the light.

While on a recent outing I bumped into an entomologist named Bug Bob.  He had sent along this web site http://bugguide.net/node/view/15740 which was most helpful in identifying bugs.  Note the Guide section

When you have an MP-E 65 or other macro lens, having good bug ID resources is key.

Hope this helps

This particular insect is within the Bug Assassin species.  I found him on the side of my SUV in roughly 70 degree weather (farenheit).  I'd not seen one of these before and wanted to test it level of skittishness.  He was not alarmed by my attempting to gently prod it with a pen.  I put him in a container and head for home.  I placed him on an indoor plant and for the most part he was rather still, not alarmed and a perfect subject to photo via the MP-E 65.  Since he did move every 10 seconds or so trying to get more than 7 images was not possible.  I wish I had spent more time and put the MT 24EX on 1/2 manual vs. E-TTL as there would have been less harsh light on its hard shelled body.  Taken at 2.5 magnification, 7 stacked images via Macro Rail.

What's For Dinner?  (Zelus tetracanthus) by Revup67, on Flickr

Revup67 – I actually never have used the ISO1233 tool before, thanks for pointing out this useful comparison tool!  I enjoyed taking a look at that flickr group, I think I’m leaning towards the 15-85 now…  You mentioned the 100mm 2.8 L is also in your collection, do you have the tripod adapter and do you consider it necessary?

Personally, the ring adapter I feel is not necessary for this lens as it is rather lightweight though I carry around a 400mm prime frequently..maybe my arms are use to the weight of the 400mm so when the 100mm is on the 7D its like a feather.  Mounting the camera body on the tripod with the 100mm and without the ring should be fine.  If in need of a superb tripod head may I suggest the http://acratech.net/product.php?productid=76 Model GP-s which can fit nicely on a Benro Travel Angel or any standard tripod Boegn, etc.  The GP-s head also acts as a Gimbal head.  No plates come with this however so you can pick and choose.  I got one for the 7D and 400mm.  The plate for the 7D with the 100mm attached is plenty as would be for a 5D mkii.  This head is rock solid - be sure to look at the instructional videos on this site.  It's a chunk of change but there's nothing worse than watching a $4000 rig fall to the ground because of a crappy tripod / head.  Luckily I caught my rig before it hit the sand.  The cheap tripod was in the trash moments later.

the cards are good but take too long this you just pop on the lens snap a shot off in the general direction and set your custom balance,
here is a review of them

I've not used one of those though I know there are a variety of brands  ranging up to $125 USD as I recall.  For me the cards (specifically the WhiBal same guy makes LensAlign) are pretty quick (they have a target for instant focus) but most importantly I found them most accurate..spot on.  No right or wrong it seems as long as one is cognizant not to use AWB or post processing without a proper WB snapshot(s) prior. 

A good B&W relies on a lot of colour information. Many B&W digital specialists will actually increase saturation to the point of oversaturation before the conversion, to deepen the tones.

Yes, this is very true.  I've done this technique myself as well as tweak the contrast which also helps.

I tried my 7D and 15-85mm EF-S at a very low light high School Play last week.  Most of the images did not have enough light or were noisy, but here is one that managed to come off at ISO 1000.  Even at !SO 1000, the 7D is noisy.

Did you shoot this in RAW?  If so, the DPP software program allows some excellent tools to mitigate any noise on the 3rd tab called NR Lens AIO.  I use it whenever I feel there's a noise issue and it does a great job of squelching.  Also check out the Blue Crane DVD's..some great tips in there such as not to use the Auto Lighting Optimizer as it can increase noise (doing this from memory but believe that was one way to also knock it down).

I use flash a lot - including bright sunshine - as it lets you control the light to bring out the subject from the background, I find turning down exposure compensation (-1/3) and flash exposure up (+1/3) just lifts the subject out of the background without using blur

Yes, this is a great idea. If no flash is permitted as you point out at a reception that raises a whole other issue with the WB.

Whatever the situation flash / no flash, higher ISO lower ISO , I would think a White Balance card needs to be included.  If a wedding photographer used the AWB or any presets that would be a cause for concern from my point of view.

I know everyone of the 5D users likes to bash the 7D with the ISO and it is true but are you really going to be using a high ISO if you have a 580 EXii flash?  that was my point.  It's hard to discern with the naked eye on an ISO 100 in RAW from a 5D to a 7D unless it's blown up to a poster size.  on an 8x10 I would be curious to know if you would truly see a difference.  Also, the original poster stated he had a limited budget in mind and trying to stay within that find limitation.  I might be hard pressed to go backward in time with a 1Dmk3s and the small LCD.  I think the 7D would out pixel this camera regardless and hold up better distortion wise.

Also, all the concern about a higher ISO with the 7D might be moot.  It would seem pointless to take those shots anyway as they wouldn't be much good no matter what camera is used.  You're gonna get noise from about 800 onward.  I'd keep the flash on for anything 800 and over

Here's a 1600 ISO shot in RAW on a 400mm 5.6 @ 1250 at dusk then shrunk to a 5148 pixel JPG then shrunk again to a 1920 pixel JPG.

Snowy Egret .......(not at the Zoo, in the Wild) by Revup67, on Flickr

Wickid - I do agree and the specs on this are rather strange as you suggest.  It's probably one of those things where they got results of an ND1000 on one lens therefore can propagate the filter can go that high.  They wouldn't dare put a disclaimer stating won't work on 99% of the lenses out there cause then sales would bomb.

In either case, I'm not sorry I acquired the filter, it was clearly worth a shot, I knew it, took the gamble and the seller had agreed to do a full refund.  Only loss was the shipping.

Quite possibly in the very near future all of these conjectures will be moot.  At that point I'd love to do a tally from those that contributed to this thread to see who was the most clairvoyant of the group.  This group or individual shall be named the official CanonRumors.com Fortune Teller.  On the other hand, I will refrain from speculating at this point, bow out on the up and coming moniker and merely watch and wait with drool and anticipation for the 5D Mkii replacement...whatever it's name and features shall be.

PS "anyone got a bib" ?

A few other key items I'd like to mention are:

#1 Get a WhiBal card for 34.95.  It will allow you you to fine tune and get the accurate White Balance setting in the room.  Order it from the Michael Tapes web site.  What a difference especially without a flash, the custom white balance within the camera will be dead on perfect with this card.  http://michaeltapesdesign.com/

#2, if you get a 7D, there's a built in wireless transmitter to use with your (hopeful) 580EX II is a huge plus so another words the 580EXII can be used off camera and hand held by your wife or on a stand.  You can configure it with the built in flash to add fill or without the built in flash (solo).  You can also set up the Master / Slave combo with an A+B+C flash (for future if you get more than one flash such as a secondary 430 EX or another 580 EXII).  The manual settings of the 7D's built in flash and the 580 EXII allow a great deal of combinations.  The diffuser on the 580EXII works with UWA lenses up to 15mm as I recall and the white pull down card is great for eye sparkle.  It also has a full 180° swivel head.  The 580EXII in most cases knows exactly the lens that is on the camera and can auto adjust when using E-TTL

Neuro -  as expected, you raise some very good arguments with MM thickness of the filters stacked.  The Hoya HD Pro ND64 is 3mm though I am not sure about the Marumi Super DHG CPL.  The test I did was on a 7D and at 15mm (with the 15-85mm lens so I am really at 24mm (approx).  It sounds like the 5D Mkiii is coming out later this month though I suspect I will get it in April after a tax refund.  If there is vignetting with the two stacked then yes, I won't have a choice but to move to the 10 stopper. 

Wickid..I didn't think the fader was soft I just found that on Max ( and near max) it was uneven with light distribution (see tests above). Per the Light Craft Facebook page, the tech rep stated I would only get 3-5 stops maximum on that Light Craft Digi Pro HD Fader filter with the 16-35 mkii lens on 16mm.  Wish I would have known that in advance.
