I actually like the way number 2 looks. It reminds me of the images of children from the second world war-era. It is not nice or sweet, but I don't think it has to be.

+1 on the x-rite. I use one of these when going for exact color replication.
In addition, when it is more of a grab-and-go-shoot occasion, I really like the lightform picture style from cineplus. For the ffew euro's it costs, it's a great addition to the camera. You also have a free studio picture style from canon itself.

A lenscaot for non-wildlife lenses would be great. Not to hade it,j but rather to protect it. Or seomething based on crazy aarons thinking putty?

Originally, I wanted to ask the OP - "Are you wondering if an L lens would allow you to drop it continuously?", but then I remembered about the warning I've got from the "trolling rights watch" (no offense :)). So, is it the first time you've dropped it?

Yes, it was the first time I dropped that particular lens, and that was from only one metre high onto a wooden floor. It was however the second time I destroyed a 50F1.4 as the first one died with exactly the same problem when a handheld scanner slipped out of my hands and hit it while it was on a camera. I have lots of other lenses (both L and non-L) and never had any issues with those, even though they are used in averse conditions (having people bump into you, backpack on bike, doorframes. tripod failure,...)

So my question was rather than "can I drop it continuously", "Do the L Lenses with internal focussing offer better protection against deformation" Because If I have to baby the 50F1.4 every time I throw it in a backpack, I might as wel save up for the 50 1.2L as i'll end up destroying more 50F1.4's in the end (Now on my third copy of the lens already)

But no offense taken for your original question, it was more about the fact that the particular lens I have is apparently very prone to issues due to the construction (so Next time, I'll replace it tiwth the L anyway)

I finally received the repaired lens, 172 euro, replacement of focus gears, barrel and cleaning of the lens elements. It works like a charm, though to my ears the focus sounds different now. I tried it next to the replacement 50 F1.4 and the results were identical when it cames to focus performance, so I guess the repair really made it as good as new.

Do you mean sort per row or sort once to pick the most pleasing one of the four cameras?

A factor of 2 in rate for an increase of 10 oC is for a reaction which is relatively fast, such as an enzyme catalysed reaction in a cell with an activation energy of about 12.5 kcal/mol (~52 kJ/mol). A slower reaction with a higher activation energy would increase a factor of 4 or 5 or more with a 10 oC rise in T.

So with two camera bodies and a controlled ten degrees difference we could work out which metal the 5DIII is made of?  :D

It also states that corrosion due to pure water increases With temperature, no mention of what temperature, but it also says the alloy is not structurally affected until temperatures of 95 to 120C.

Quick rule of reaction speed is an increase of speed at a  factor 2  for every ten degrees Kelvin (or Celcius) rise in temperature. So the hotter something is, the faster the chemical reaction will work (which you can experiment with by washing dishes in hot water vs cold water)

Pure water is less corrosive than water with salt as well (which also is a better conductor of electricity, increasing the chance of short-circuits)

Software & Accessories / Expierience with laminating photo's?
« on: July 29, 2013, 08:26:58 AM »
Does anybody here have experience with laminating their pictures? i saw Fellowes has matte laminating pouches when visiting a school supplies store and the results looked pretty good on the example pictures they had laminated, so I was wondering does anybody have experience in laminating their pictures? I'm considering getting it for making my prints (pixma pro 100) a bit more resistant to the kids when they are pinned to the wall, but I'm wondering if it could create issues with the ink and canon papers.

EOS Bodies - For Stills / Re: Dpreview tested the 100D
« on: July 29, 2013, 07:57:33 AM »
I use both the 100D and the 7D and I must confess that I love the 100D for portability and it is very easy to get used to the touchscreen (so much that I miss it when switching to the 7D) but I do find it very hard to focus in darkness with the 100D, even with F1.8 and F1.4 lenses. On many occasions, I've had to switch to manual focus as it simply would not lock on, while the 7D had no problems. It only happens with low-light situations though (dark dress in a forest at nightfall for example)

Just out of curiosity, would leaving the lens off in a dry environment help with removing water from the body and thus preventing corrosion? (like condensation when you change lenses in the rain) SO would it be a good option to have it rest for a while without lens cap after a shoot to prevent prolongued exposure to corrosion;

The original is sent to canon for repairs, so I'll keep you guys informed of what the cost here (Europe- benelux) is. The store said it could take up to six weeks and they'll keep me informed of the cost before doing the actual repair. if the cost would be too high, I can forfeit the lens and they would not charge examination costs (50 euro)

the adhesive can be removed without a problem... and without a trace. 
just use a hair dryer to warm it up a little and remove it.

So far, the best remover for all kinds of glue without damaging the original surface has been rain-x. I've used that on painted plastics and plastic screens without any problem. It's originally intended to prevent water from sticking to windshields, but it works excellent for removing glue residue.

The replacement has arrived and it now has the new style cover, but I'm really tempted to have the old one repaired as well seeing that most of you spent less than half of the value of a new one on it. and it would be convenient to have a spare.
