Lenses / Re: Choose your Weapon: Ultra Wide Zooms for Canon
« on: September 17, 2014, 05:49:03 AM »
I have the 17-40/4L, but I'm lusting for the 16-35/4L IS.

Yes, I'm a geek and I have GAS.  ;D

Lenses / Re: The Sigma 35mm Art is Toasting Canon's?

The optical performance is really good, but several people have reported about AF consistency issues here, even after going through 2-3-4 copies of the 35A and 50A lenses.

The amount of issues have at been enough to at least discourage myself from looking further into getting a 50A at the moment.

Lenses / Re: Which Tilt/Shift lens to choose?
« on: September 16, 2014, 09:38:16 AM »
Thanks for all the comments, I really appreciate the collective knowledge and wisdom here.

Keep in mind when making that decision that ably the newer MkII 17mm & 24mm are in fact 'L' Lenses, the older build 45 & 90 are not.

There are differences between the two, there's an expectation that quite soon Canon will upgrade the 45 & 90, so you may want to hold on your decision for a while, but with Canon lately you may also want to ignore that & decide which of the current 17 & 24 suits your needs best.
Indeed. I stopped waiting for the 7D2 two years ago and bought the 5D3, as an example. But the point about the independent rotation of tilt & shift is duly noted.

I would recommend the MII 24mm, both 24mm are L's but the MkII is considerably better both in IQ and functionality.

It will give you more "selective focus" control than the 17, it takes standard sized filters, with a 2XTC it will go to 48mm so you get even more selective focus.

The 45mm is a comparative dog, it desperately needs upgrading.

Hmmm. Using TDP's ISO charts to compare a 24mm L II + 2x TC with the 45mm, and there the 24mm+2xTC are quite soft in the center (even when comparing f/7.1 vs f/2.8 ). Stopping the 45mm down to f/5.6 or f/8 makes it sharper all around.
What am I missing here?

The 90mm blows the 45mm out of the water, optically. Especially if you put the 2x TC on the 45mm, it gets horrible.

As for the price, the 45mm and 90mm are in the 5.000-6.100DKK range (USD870-1.060), whereas the 24L MkII is 9.500DKK (USD1.650).

Since noone have objected to my statement about 17mm & 24mm = architecture and 90mm = product shots, I presume this is right. I guess the addition is now "45mm = The Dog, avoid it at all cost" ;D

Lenses / Which Tilt/Shift lens to choose?
« on: September 15, 2014, 06:00:37 PM »
I've been looking at the tilt/shift lenses for some time, and the ability to change the focus wedge is appealing to my geeky side. As usual, googling for which tilt/shift lenses are used for what, is just as futile as trying to drink from a firehose :(

I guess that the 17mm and 24mm are primarily used for architecture and landscape work, and the 90mm for products (and that miniature effect). But what about the 45mm?

Since I am mostly thinking to use selective focus (tilt), I presume that the 45mm and 90mm are more obvious tools. However, since I already have the 1.4x and 2x (MkIII) extenders in, one option could be to use an extender with the 24mm, allowing me to dabble in architectual shots as well..

Looking at the local 2nd hand market, it seems that there are a bunch of 24mm, 45mm, and 90mm available for reasonable cost, but which focal length would be the obvious choice?

I have zooms in the similar focal length areas, but no primes yet. I'm (also) tempted to get the 100mm L-macro too, but that's a seperate topic.

Edit: I'm shooting on a FF camera (5D3).

I will say now, after having shot a soccer match tonight, that the 400 f/2.8L II IS auto focuses MUCH faster than my version 1 I had.  I had 615 razor sharp photos, which is way too many but that was not even possible with my version 1.  Well worth the cost in my opinion.  Great shots to all who have posted here and I plan to keep contributing.  Thanks.

That's interesting, and good to know.   Do you think it's the same with the 300 2.8IS and 2.8ISii?  I sometimes think my 300 2.8IS isn't as fast to AF as my 70-200 2.8ii.

Agree this is interesting, as I haven't read/heard this before (I mainly go to TDP for reviews).

As for the 300mm MkI and MkII lenses, I did not notice any major differences in AF speed on my 5D3 when I tested them back to back a couple of weeks back. Since MkI lens left my home together with it's new (and happy) owner earlier today, I am no longer able to do an actual test for you, sorry.

I occasionally read posts from users wanting portable storage to take into the field with them.  This device seems to answer some of their requirements without costing a fortune.
Well spotted, Mt Spokane! I did see the product name, but never noticed that it had built-in battery and SD reader :)

I wonder if I could put Eye-FI cards in the5D3 and use this to connect to the WD drive. That might actually give a purpose to it's SD slot :D

Actuance, did you try to use the "Zoom" mode during Target Setup? I have found that I usually have to engage the Zoom mode to detect the target correctly during the alignment/setup check phase. But once it is setup, I've had no problems in getting FoCal to work.

Ohhh.  So I should set up the target at the recommended distance (50X)
use the zoom function in FoCal for running the target check tool
then zoom out for the AFMA tests?

Yes, that is exactly what I meant.


Sony and Samsung are fortifying a two-superpower structure in the digital camera market in Korea. Traditional market leaders such as Canon, Nikon, and Olympus are losing ground.

The article sounds more like a marketing brief from Sony than a real article.

The problem was that using the target checking tool, the software was unable to detect the target.  Well, small wonder because with a 35mm lens at 1.7 meters the A4 target is pretty small... too small in my opinion.  In looking at the figures in the manual, it appeared to me that the camera needs to be closer.

So I moved the camera closer to the target.  The new distance was 0.8 meters.  Ran the target checker and there was no problem.  No problems with any of the tests.

Did I miss-interprete the instructions when I orginally placed my focal plane 1.7 meters (50x FL)?

Actuance, did you try to use the "Zoom" mode during Target Setup? I have found that I usually have to engage the Zoom mode to detect the target correctly during the alignment/setup check phase. But once it is setup, I've had no problems in getting FoCal to work.

Last time I tested a lens, I had an EV just below the recommended 8.0, without getting target detection problems, so a lack of light should not be your problem.

Unfortunately, he wasn't as cooperative when I was there 2 weeks ago :(

What gimbal type head is everyone using?   I've seen prices ranging from $85 (Yikes!) to $600.  I use RRS plates and a Benro monopod for soccer games.

Wimberley seems to be the gold standard, but seeing that you already have a Benro monopod, I thought I would recommend the Benro's GH2 (I have one). For my amateur use, it has been excellent. I haven't used it as much as I would have liked to, but that is due to other circumstances.

If you want a model that can be taken apart like the RRS, take a look at the GH3. The GH3 can also be used for multi-row panoramas.

Canon General / Re: Neutral Density Filters - HELP !
« on: August 04, 2014, 05:46:56 AM »
If you don't want to spend all that cash for the Lee system, I can recommend the Tiffen ND filter kit:

It's worked well for me for a couple of years now and the filters stack fine on their own or with my B+W XS-PRO C-PL, which is usually what I stack them with.  Here are some sample shots from another ND filter thread:

Alas, I cannot recommend Tiffen's ND0.9 filters as it reduces the contrast quite a lot.

Bryan Carnathan found the same thing in his 10-stop ND filter test

This was shot fairly far north, so this is as dark as it gets. You can still shoot handheld, with acceptable shutter speeds, apertures and ISO settings, 24 hours a day. At the far north they still have midnight sun. But further south, where I´m heading, it is getting quite a bit darker now.

If anyone wants exceptional light and exceptional scenery to shoot, I can really recommend the north of Norway. And this year, the weather has been phenomenal.

+1 on the exceptional scenery, and +1 for the weather this summer - seems like all of Scandinavia has had exceptionally hot and sunny weather this summer  :D

I recently got hold of a Benro ND1000 filter in both 77mm and 82mm. I tested them up against a Tiffen ND0.9 filter and posted the data here. Short story: the Tiffen is crap, whereas the Benro seems quite good. Benro also makes a 100x100m filter.

82mm WMC filter: http://detail.tmall.com/item.htm?id=37661410338

Maybe you can find these in Europe somewhere (I was in China when I bought them, so I just got them directly off taobao)

I have the ThinkTank Retrospective 30, and it takes an impressive amount of gear. As a walkaround bag, i generally can have 5d3 with 24-70 attached, a 70-200/2.8 and a 17-40 in the main compartment, plus C-pol filters etc. Flash goes in the front pockets.

For carry-on/flight purposes, it will take all my sensitive lenses & 2 bodies, and still be at 10.2kg. TTP doesn't recommend that, though.

Apologies for the cellphone picture quality. I bought it as a phone, not a camera :)
