Lenses / Re: I'm done - I have all the lenses I need
« on: May 07, 2014, 05:43:01 PM »
Most of the lenses you own can be improved in one way or another. So I guess at the moment you have a pretty good set of lenses to cover your work. But every new sensor demands more and more of your lens, so an update becomes inevitable sooner or later. I saw it with older medium format lenses adapted to a modern Canon ff camera body. The results are less than mediocre and so I really appreciate newer lens designs and coatings.

I have no shortage of lenses but still want better ones. Especially a proper tilt-shift lens in the range of 40mm till 60mm is lacking.

Hi,
I use mainly the TS-E 24mm II. But the TS-E 45mm is also used from time to time. Seldomly the TS-E 90mm is used, although it is clearly sharper than the TS-E 45mm. I use some mm of shift in almost every panorama to compose the picture. But I try to avoid multi row panos, so normal lenses are no longer used. In the past I had good results with the EF 35m L and the EF 50mm f1.4 too.

I like the view of wide angle lenses (24 till 35mm) but I don't like the perspective change of super wide angle lenses because of the too strong accentuation of the foreground. With the tele lenses the compression of the scence is often clearly visible, no matter how wide the panorama later on is. The whole scene looks then easily a bit flat. So I choose the focal length depending on the intended compression of the scene and also the needed final picture size later on.

They are great once you get past the initial learning curve.  It's actually somewhat difficult to go back to normal lenses after you use T/S ones and you wonder why all lenses can't be T/S :)

After having bought 5 tilt shift lenses I can fully understand your statement above :) Same for me.

TS-E 45mm f/2.8L II
or
TS-E 43mm f/2.8L

Totally agree! But a TS-E 50mm f/2.8L would also be OK.

Hi,
A toy effect as seen in the vimeo video can't be done with the Canon TS-E lenses. The effect of the TS-E 24mm, TS-E 45mm and even the TS-E 90mm is less strong. It's clearly visible in the video that different focal lengths were used and the toy effect applied in post production. The transion between the sharp and the blurred parts is not smooth enough and both blurred parts of the frame look identically blurred, which is normally not the case with a TS-E lens.

BTW, the use of a large aperture already helps a lot to achieve such a effect.

Lighting / Re: Cheap decent softbox for a traveller
« on: April 09, 2014, 01:06:36 PM »
For off-camera flash I love the orbis ring flash. It produces a rather soft light, more similar to a softbox than to a traditional ring flash. It's not really cheap but pretty small and robust. It also fits various brands of flash guns.

Zion National Park in March 2014

I really like the composition of your pictures, which were very well done in all 3 of them. The use of leading lines was well done.

BTW, are these HDRs? Somehow for me they seem to be unreal. The dark skies suggest a rather dull light but there is such a lot of detail in your pictures. The scenes are brighter and the colors more satured than it would normally be the case with such a sky and time of the day. The reflections in the water does not seem to match the sky in all 3 pictures. There are no shadows at all. Especially the first image looks like a collage of at least 3 photos. So for me the post processing seems to be overdone.

Lenses / Re: Lee Filter Adapter Question
« on: March 26, 2014, 08:04:58 PM »
Hi,
I use the Hitech filters in a Lee filter holder. The Hitech filters were cheaper and easier to get. I though about switching to Lee for a while already but can't imagine that the image quality would improve enough to justify the investment. The newer Hitech filters like the reverse grad NDs or ProStop IRND are also a bit better than my older grad NDs. A single Hitech grad ND or a Hitech grad ND + pol filter is fine. Two Hitech grad ND filters is not such a good idea because you may notice a tiny bit of haze caused by 3mm of additional plastic infront of your lens. But the pictures are still pretty good.

BTW, depending on the exact position of the Hitech reverse grad filter to the sun, a much more reddish picture can be the result. This is often quite welcome. The attached photo shows the efect quite well. Both pics are out of cam but resized. Half of the 2nd one was stacked up as a layer on the 1st one. They were taken seconds apart and differ only in the position of the reverse grad filter and shutter speed (1/15sec vs 1/5sec).

Best regards, Robert

Hi,
A good alternative to the Lee Big Stopper is the newest 10 stop "Resin ProStop IRND" filter from Hitech. I got the 6 stop and 10 stop version of this filter some months ago and they are great! The pictures show almost no color cast anymore. I also have the two previous versions from Hitech, which I hardly every used because of the strong color cast. As far as I know the Lee Big Stopper is also prone to a rather strong blue color cast.

Much more usefull than ND filters are grad ND filters. For spectacular sunsets/sunrises a reverse ND filter is needed. If you are willing to be bothered by an adapter ring and unwiedly filter holder, get at least a 2 stop soft grad ND and 2 stop reverse grad ND filter. From my collection of more than a dozen grad and reverse grad ND filters, these are the 2 filters I use most. A matching pol filter in 105mm is quite expensive but definitely pays off. My rather cheap Sigma EX DG 105mm pol filter does a pretty good job for couple of years already. I do have some B+W pol filters in smaller diameters but I still couldn't justify the price of a 105mm B+W pol filter while having the Sigma one.

Kind regards, Robert

Hi,

Without the help of reverse grad ND filters the picture shown in my post above would look like the attachment. It was a quick test shot some minutes earlier. The shot is a straight out of cam jpeg, just reduzed in size.
As you can see, the use of a filter adapter and some proper filters can really make a difference. Fortunately the new Lee Adapter Ring for the TS-E 17mm makes it much easier now.

EDIT:
One other point worth noting is that the benefits of an ND grad can be derived in software.  Before I had my adapter, I bracketed shots and used the ND grad feature in Adobe RAW to replicate the use of an ND grad.

I often use the ND grad option offered by Lightroom but still carry a big selection of ND grads and reverse ND grads with me. Post processing has its limits, especially with Canon sensors. ND grads can make it much easier. See the attached picture, which I took recently with the help of the comination of a 3 stop reverse ND grad and a 2 stop reverse ND grad. No HDR technique was used but in post processsing I used the digital grad ND offered by Lightroom as well.

@RobertG
Robert, could you tell me what kinda head mount the Zörk adapter uses. Is it the Arca-Swiss type or the Manfrotto quick release type? Thank you in advance.

Alan,
The Zörk adapter has no specific head mount. It offers just a 3/8" mount and a 1/4" mount. See http://www.canonrumors.com/forum/index.php?topic=8286.msg151511 I attached a cheap quick release plate to it with the 3/8" mount.

To say the truth I seldom use the Zörk adapter nowadays. A Markins L-bracket is attached to my 5D II for while now and I'm lazy, so I just put the camera onto the panorama plate. For landscape panoramas it works quite well because Kolor Autopano Giga makes really good job.
