Lenses / Re: Cheap UV filters
« on: January 11, 2012, 09:33:48 AM »

I did a little test of my own, with a UV transilluminator (used to view gels stained with ethidium bromide, a flourescent dye used to label DNA).  The bulbs are essentially the same as blacklight bulbs - substantial output in the UV range, and a smaller output in the visible range.  Humans are nominally sensitive to 400-700 nm light, and wavelengths below 400 nm are UV, while above 700 nm is IR.  A typical blacklight bulb has a main peak at 370 nm with a 20 nm width, and a secondary peak from a mercury line at 404 nm - it's the 404 nm light that we can see. 

Wouldn't it be pretty easy to test the UV filters on a transilluminator by just placing the filter on the transilluminator, and a standard UV cuvette with a cheap fluorescent dye like ethidium bromide on the filter. If we see fluorescence, the filter does not block the light? Assuming that you do not care to play around with EtBr on your camera equipment...
Otherwise fluorescein might be a non-toxic alternative, but then a different source of UV light would be necessary.

Check this out...

Pay attention to this:
"not available
Product is no longer available. Only listed for information purposes."

Can this mean that Canon will release the EOS 70D sooner than later? Maybe during the CES?


Regarding the EOS 7D, they seem to be selling the last available units.

Pay attention to this:
"Remaining stock
Remaining stock. Ready for shipping within, ready for shipping within 2-3 business days"

This online shop is a reference in Europe.

I wrote this in another topic... At this point, EOS 7D is in the same situation.

meanwhile sais that the 7D is no longer available, only listed for information purposes.

Thank you all for your comments and the pictures posted here! I will go for the Canon 10-22, I think the extra range compared to the Tokina 11-16 will be nice to have.

Lenses / UW lens recommendation for 7d?
« on: January 01, 2012, 05:54:22 PM »
Which lens would you recommend as a UW lens for a 7d?
I am thinking to buy the Canon 10-22, but there are alternatives from Tokina and Sigma with similar ranges. I have a Canon 24-105, but sometimes I wish to have another lens as a wide angle addition. I would prefer EF mount for upgrading options to FF, but know that the Canon 10-22 has EF-S mount, which might also be okay, as I do not plan to sell the 7d.
Thank you all, your recommendations are highly appreciated.

+1 on the EasyJet once you get over there, book long enough in advance and pay like $10 a seat, the unlimited-weight-as-long-as-you-can-carry-it-yourself has proven more than useful for me in the past.

Also, I've never flown through Frankfurt, though I've done Schiphol, Heathrow, Gatwick, Stanstead, Luton all often enough that I wouldn't bother. You're probably better off going to Frankfurt for any continent-based travel, then hop on a german ICE fast-train, book up to 90 days in advance and you can generally get anywhere between NL, Belgium, Germany, Denmark, Poland, Austria, Switzerland for as little as €30, much preferable to flying and take all you can carry (also, you get as much leg-room as business class on a plane).

Unfortunately the times are almost gone when you could easily get a 0.10, 1 or 10 Euro ticket (+ taxes) from the low fare airlines in Europe, rather calculate with 50 to 100 Euro for each flight now. If you choose a connection flight with one of these airlines check their luggage policy carefully, some charge a lot for each individual piece of lagguage or based on the actual weight. Avoid Ryanair, they have a horrible pricing system. You will have to pay to pay your ticket with a credit card, you even have to pay for check-in. Ryanair is thinking about replacing seats with some kind of stools and they even plan to charge you for using the on-board toilet.

Be aware, that some of the low fare airlines (e.g. Ryanair) call they destination London or Frankfurt or watever, but actually they use airports which are far outside the city centers which takes a lot additional time for transfer. Often these airports are not the main airports with the intercontinental connection flights, e.g. coach transfer London Stanstead (Ryanair) -> Heathrow will need up to 2 hours during rush hour.

In general, I would recommend to book your flights from a single carrier, than you are on the safe site with your luggage size and weight.

IMHO Heathrow is ok if it is your final destination or if you are using BA and a connecting flight also with BA. Then you do not need to change terminals (BA has a new one and the luggage problem from the opening time seems to be solved), but it might not be a very good idea if you take a different carrier to Heathrow.
Many do not like Schipol, I think it is fine. Normally the queues are short, but the food corner could profit from some extension.
Frankfurt has meanwhile finished most of the terminal reconstructions which was necessary because of the introduction of the A380 fleet to Lufthansa, I can not say anything bad about this airport. The railway station is convieniently located next to the terminal building.
If you are using Delta/Skyteam, Paris might be the first stop in Europe. It would be wise not to choose tight connecting times there, it usually takes a little bit longer there (long walking distances!).

But if you found a flight which looks good to you,  just take it, enjoy and have fun!

However I would like a screen that gives as true a colour representation as is possible in a laptop. (Can they be calibrated?).

The Lenovo W520 series has the option for a build-in colour sensor to calibrate the display (you need to close the lid for that, because it is in the hand rest). But the W520s are massive and heavy, probably nothing for frequent flyer's and lightweight traveling.

Lenses / Re: Canon 24-105mm and 100mm lenses with impurities
« on: December 19, 2011, 05:30:15 AM »
Just for my understanding, if a zoom lens like the 24-105 is extended it needs to soak in air to compensate for the increase in volume in the lens tube. Is there a kind of air filter which prevents dust from being soaked in? If not, it is probably not possible to keep the lens interior dust-free over the long term?

I am loving my gorillapod focus (with Manfrotto 494RC2 ball head) when going out for hiking. Lightweight, robust and small enough to be tied to the backpack. Of course it can not fully replace a sturdy tripod but often you do not want to carry one up the mountains.

EOS Bodies / Re: Canon 5D X
« on: October 25, 2011, 08:51:56 AM »
Canon went as far as III in their lineup with the 1d series.
You forgot the 1D Mark IV.

Calling it the 5D X would make not make sense if you take Chuck Westfall's explanation for the X:
  • X for extreme (X-treme) performance
  • X for cross-over (X-over), since this represents the merging of Canon's two pro digital SLR cameras, the higher-resolution EOS-1Ds Mark III and higher-performance EOS-1D Mark IV, into a single next-generation model
  • The Roman numeral X, as in 10, because the EOS-1D X represents the 10th generation of pro-class SLR from Canon since the F-1 debuted in 1971

If Canon would regard the 5D series as pro-class, then only the last one would apply.
So my bet is on "Canon EOS 5D Mark III".
Funny that only the 1 series has the dash between "EOS" and the digit.

By the way, am I correct in these 10 generations?
  • Canon F-1
  • Canon New F-1
  • Canon T90
  • Canon EOS-1, 1N and 1N RS
  • Canon EOS-1v
  • Canon EOS-1D and 1Ds
  • Canon EOS-1D Mark II and 1Ds Mark II
  • Canon EOS-1D Mark III and 1Ds Mark III
  • Canon EOS-1D Mark IV
  • Canon EOS-1D X

According to the video posted earlier ( the X in 1DX was chosen because it is indeed the 10th generation of the EOS 1 series. Next 5D will probably be a 5D MkIII.

EOS Bodies / Re: EOS-1D X Canon USA Press Release - video function
« on: October 18, 2011, 03:52:25 AM »
As somebody not really interested in the video options the current cameras offer, just a short question for my understanding. Are there SLR cameras in the market having continuous AF in video mode? I just wonder if it is technically so challenging to do it, that Canon does not even include it in the top model? Or do Pro Video Shooters prefere to set it by hand, which might be a little bit unhandy with the currentl lenses.

400D, 100mm f2.8 L, handheld, ouch!

If a new camera would be announced at the event on October 18th, does it make sense to invite CPS platinum members and presenting something different then a new top level (1D5) camera?
