with a Stofen.
why? for outdoor shots, it's not like the flash is going to bounce off of anything... a sto-fen would just cost you flash power.

So, seems to be a lot of mis-conceptions here.
The powder is cornstarch with food coloring. Unless you have a food coloring allergy, respiratory issues or are allergic to corn there isn't much to worry about. I have shot 3-4 of these for my local paper and two for the company that runs them and feel just fine afterwards. A painters mask reduces the amount you inhale by quite a large margin. If you want to filter it all out you will need a good respirator.
It's cornstarch, it dissolves quickly. It'd be a different thing if it was silicone based powder as that would sit in the lungs forever.
I know you're asking about lenses, but how are you doing about lighting? You mentioned your 580exii, but portraiture is one that usually calls for more complex set-ups. We all know pictures are made or break by their light.
From time to time i bump into this pearl of wisdom.
Since this is CR and not Instagram's "#look what i ate today!" lets see some examples of how difficult it really is to exceeded the capabilities of the 7d in question:
- Do you still get random OOFs when tracking even though you played with the settings and your technique is adequate?
- Have you ever hit buffer limit?
- Ever disappointed by WB under artificial lighting?
- You tried to lift shadows only to find the surprise underneath?
- You get sky noise even though you're shooting below 400?
- You dont get useful 1600s+?
- Did you ever tried autoiso only to find its a slopy implementation?
- Weak AF under low light?
- Meter goes bananas in challenging situations?
Have you ever bumped into any of the situations above? Well congrats you are one of the "two (maybe three) people on the planet who have actually exceeded the capabilities of the equipment they already own" according to SiliconVoiD
Just why do you think it needs one?
dSLR sensors are insensitive to UV light. If you really want one (maybe you're shooting film?), there's a drop-in holder for gelatin filters that comes with the lens, and a different one sold separately for screw-in 52mm filters.
If you mean a front filter for protection, the old superteles had a protective meniscus lens (thin, non-refracting, relatively cheap to replace). They removed it from the new MkII versions to save weight. The hoods for those lenses are very deep and offer substantial protection.
A screw-on filter of that size would be incredibly difficult to produce. Compare 82mm filter costs to 58mm filters - the difference in materials cost is minimal, you're paying for the precision to make the two surfaces perfectly flat (which is harder than making curves surfaces) and parallel - that need for precision goes up exponentially with diameter, and a 600/4 would need a >150mm front filter.
Is there a reason you think you need a focal length beyond 85mm or 105mm? I've never been to that part of the world, but imagine that most of the photo opportunities will be on the wide to normal focal lengths. Remember that the 7D is a crop body and will provide an effective 1.6x zoom on the lenses you decide to take on the trip. If you are set on taking your Tokina 11-16mm, I'd recommend a 24-105mm f/4L IS zoom. They can be had at very good prices for a lens that was sold as part of a kit; maybe better priced if you don't mind a slightly used lens. I think you will find that 105mm on a 7D long enough and if not, you have 18MP to work with and crop.
If you wanted a one lens solution know that there are IQ compromises with any of the super zooms that you mention. If again, you can live with 85mm on the long end, I would recommend the Canon 15-85mm EFS USM IS lens. It is wide enough that you might just leave the Tokina at home and travel ultra light. Maybe throw in a 40mm f/2.8 USM (cheap at $150) for the times you need a wider aperture.
Good luck with whatever you choose and have a fun time in Israel!
The sale still shows up. Sometimes, a product is sold out by multiple buyers processing orders at the same time, Canon sells maybe hundreds or thousands of some lenses. They cancel the orders they can't fill if this happens.
This happened to me with the super popular 70-200mm f/2.8L MK II. The next time it was on sale, I bought it in time.
I called and the rep didn't have any idea what happened. Then she said it was out of stock so she couldn't put in my order. She offered to honor the sale once it comes back in stock. I'm curious, did you get an email from Canon letting you know what happened? Or did they just cancel your order? That seems like pretty poor customer service. At the least I should have gotten an email that says, "Sorry we weren't able to fill your order". Plus they charged me, which is also strange. Just frustrating. I thought I was getting a 600ex this week, I guess not!
