Lenses / Best landscape lenses
« on: December 15, 2012, 04:31:55 PM »
I asked this elsewhere, but I figured I'd ask it here, too:

I'm thinking of getting into landscape photography, which was an interest of mine I never really pursued.

I started with 135 (Velvia) and then went to 6x7 and eventually 4x5. And while I found 4x5 had everything I needed (amazing IQ, color, lens movements) it was too expensive and slow. I'm not a patient person I guess.

I'm thinking of selling off either my entire 4x5 kit or most of it and investing the money in T/S lenses for my 5D Mark III. I strongly, strongly prefer the IQ and color on 4x5 Velvia, but it is too much work to shoot and too expensive. I'm just too lazy.

My favorite focal lengths were 135mm, 180mm, and 300mm. What lenses should I get to mimic these? The 24mm TSE II seems like the best performer, but the 45mm and 90mm seem like they would give me the FOV I like. But the corner performance... yuck.

Then I'd get an ND 1.5 so I could do the long shutter speeds I like. Does that make sense?

Has anyone successfully been able to get velvia style color and tonality out of a Canon sensor? I'd overexpose a bit, meter so that the scenes I shot only had 4-5 stops of DR (very low contrast scenes), etc. But is there some way to match color (LUT)?


I personally find the difference most significant for portraiture, low light, and autofocus.

For UWA the difference isn't great unless you use tilt shift lenses, which make more sense on FF.

The 50mm f1.8 on a 5D is such a great combo. And autofocus with long lenses is stellar with the Mark III. Tonality, micocontrast, etc. are improved. A 1.5 stop advantage over the 7D sounds right.

Macro is worse.

anyone else interested in a 35mm tilt shift?  the 17 and 24 are great (have both), but sometimes a little wide still.  45 strikes me as a little long, but a 35mm would be fantastic!  that or an aps-h 7dii...

Yeah, I'd like one of those. I don't think 45mm is that short, though. It's a nice focal length at which landscapes look natural without feeling flat. 24mm begins to feel "wide" for sure.

Those who can manage good landscape photography at 60-90mm impress me most.

So after hours of reading, I'm still not sure about the answer to 2 questions about the 5D mkIII, both of which are probably known by anybody who's been shooting a lot of video with one:

1) Are SD cards good enough for video?  There is endless discussion about CF being faster, yada yada, raw burst rates, etc - I don't care, I only shoot video.  Are SD cards (assuming class 10) fast enough for video use in either video codec mode?

2) Has the ALL-I vs IPB thing been resolved?  All the reading I see shows a lot of disagreement as to which codec to use generally; All-I is better on paper but many people are getting same or better results with IPB.  Anybody know?  I generally have to shoot hours of interviews per day and so would rather have a more compact codec if there is no difference in quality.

There are rumors that CF cards (the fastest ones) can record to 100mb/sec instead of 90mb/sec.

I'm not buying it.

ALL-I is a lot better for fast motion, but IPB might be a little better for relatively static scenes. I'd go with IPB in your situation, though I use ALL-I for some stuff.

Of course it's a joke, but it's a joke on the kind of thinking you're exercising, fetishizing labels and marketing and such over performance. A good sample of the f1.8 is already as sharp as the others. It's not just for "amateurs" and I got my copy (my most-used lens on my 5D III by far) from a photographer who's published maybe like a dozen books and it's one of his favorite lenses.

The MF 55mm f1.4 Zeiss might end up being incredible as might the new Leica, seeing as they're using weird designs. But the normal fast fifties are already pretty good and similar performers at normal stops.

I'm interested in the 45mm if it's not too expensive. 24mm is a bit too wide for landscapes... Something closer to 150mm on a view camera could be great.

You know...

Just occured to me...this is all just DATA...wonder why there isn't some way to just stream off the image data via the USB port straight to computer or via a usb wireless dongle to a computer, and just bypass HDMI altogether?

Just a thought...


USB2 has a theoretical maximum sustained transfer rate of 480mb/sec. In practice, it's closer to half that.

HDMI video (8 bit NTSC) is 30fps*1080 vertical pixels*1920 horizontal pixels*8 bit color*3 channels=about 1500mb/sec.

Way too much data.

Fimmakers shoot with film cameras, videographers shoot with video cameras. The C100 is a video camera, not a film camera.

Most directors don't shoot on anything; that's the DP's job and most capable DPs shoot both film and digital, though certainly they have their preferences. Also, film is going away very fast but I doubt the term "filmmaker" will.

EOS Bodies - For Video / Re: Upgrade from 7D to 6D or MK3?
« on: December 06, 2012, 12:24:07 AM »
The 5D III falls far short of the BMC camera in terms of test charts and footage pushed far one way or the other, but you have to weight that against lens availability and how ridiculously easy it is to shoot and post with the Mark III. It's pretty darned good until it's directly in comparison with something better. For video I feel it is very underrated. If you do everything yourself and are very technical (you're either an amateur who shoots very little or a professional house that does studio stuff only) something like the BMC or Scarlet makes sense. But for ease of use and fast turn around times, the dSLRs are great.

The 5D also has darned nice color rendering. And FF lets you use a fast borderline UWA (24mm f1.4), whereas no 16mm f1.4 or 18mm f1.4 exists for APS-C. So for low light the 5D III is AMAZING.

Compared with the 6D I'd get the Mark III for sure--less aliasing, surely better low light, etc.

The 7D Mark II might be even better and you won't need to change lenses, though!

I have a 60d but I have an opportunity to upgrade it at a reasonable price and get a 5d Mark III. My only worry is that I will miss the extra reach I was getting with APS-C and the vari-angle screen(but thats more of a minor concern). I have a 5d Mark II and love the full frame but worried I am going to miss the reach.
I do weddings, portraits, concerts and videos of all sorts. I dont have any ef-s lenses.
Is the image quality worth the difference and loss in reach?

You're asking for video specifically or for stills? Just wondering because of where you posted this.

Anyhow, you can always buy a longer, slower lens, but for concerts you'll lose something. The 5D has about a 1.6 stop edge in ISO for stills and a two or three stop edge for video and less skew. I thought the super shallow focus would bug me, but it doesn't. The Mark III is a good camera, underrated partially due to its versatility.

16mm f1.4 for APS-C only.

For video. Samyang?

35mm TSE would be nice. 24mm is too wide for many landscapes.

200m f2 IS of course already exists.

Lenses / Re: APS-C lens mm are correct
« on: December 03, 2012, 09:19:36 PM »
I've done it myself. I took a picture with the following configuration and the pictures were identical.

Canon 7d with 18-135mm lens at 35mm.
Canon Rebel (film, so full frame) with 35-80mm lens at 35mm.

Why did the picture turn out the exact same? Because the 18-135mm at 35mm is at 35mm on my 7D. Since this is an APS-C only lens, the stated focal length is correct. It was not "zoomed" in to 56mm. The picture was IDENTICAL to the Canon film Rebel at 35mm.

Do it yourself and be amazed.

Get an APS-C-only lens and sent it to XYmm on a crop body. Then, get a EF lens and set it to the same XYmm on a full frame body and the two images will be the same. (I understand that the image will be different if an EF lens at the same focal length will be different when put on an APS-C body). Trust me, do exactly what I said and you will see that I am correct.

Do it right now and report back.

I don't know what to say, but you're the only person who's experiencing this. Everything everyone else is writing is both consistent and correct (even if there are arguments over semantics relating to focal length not being an absolute measure of field of view).

I had a 17-55mm on my t2i and a 17-40mm on my 5D III. Used both very frequently at 17mm.

One of them was a lot wider.

I'm sorry to be so blunt, but you're wrong. "Equivalent" doesn't mean the focal lengths are mis-marked and 35mm on the EF-S lens is the same as 35mm on the EF lens exactly; what equivalent means is it's the equivalent field of view in terms of what 135 film or a FF sensor would see.

If this were true, the 10-22mm would be the widest Canon lens available for any dSLR. But the 14mm f2.8 is wider on FF than the 10mm is on a crop body.

All focal length means is the distance from the focal plane at which the lens's optical center focuses at infinity. That distance and the size of the sensor determines the field of view.

Lenses / Re: Wide Angle on a Budget

I would also recommend the Samyang 14mm f2.8 if its wide enough for you. I also have a 7D and I've been using the Samyang 14mm alot lately. Its really sharp for the price and my only complain is the distortion (which is expected for such a wide lens)

At the 14mm focal length its very easy to zone focus so the lack of AF wont be much of an issue.

Amazing performance for the money if you don't mind MF, but the distortion is much worse than it should be. The 14mm f2.8 L II has almost no distortion. Even the 17-40mm f4 L has much less. It's really, really bad and needs correction in post more often than not.

« on: November 28, 2012, 11:58:17 PM »
I know it's not f2.8, but consider getting the EF-S 10-22 f3.5-4.5.  When dealing with wide angle, losing one stop is not a huge deal.  A used or refurbished version should be less than your budget.

The 11-16mm Tokina is a little worse in terms of IQ (due to some chromatic aberration, which can be fixed in post) but it's f2.8 through the zoom range and build quality is great. It's an excellent lens. Very excellent for the money.

28mm is not very wide on the 7D, fwiw. That said, for landscapes it is my favorite focal length on APS-C. I don't like the distorted look for most landscapes. I prefer tilt/shift lenses but they are expensive.

The 17-55mm f2.8 IS is awesome in general.

EOS Bodies - For Video / Re: Quick help needed: Manual White Balance
« on: November 26, 2012, 04:06:10 PM »
White paper is bad, yes. It will work in a pinch, but why even use it?

For video you don't white balance on a per-shot basis because the final result (the scene itself) has to be consistent. That's why lighting is such an art... you need to make the wide shot look good, then relight the CUs so they look good (usually a little fill and softer light) but they also cut believably in terms of ratios, quality of light, amount of light (retain a similar f-stop), color temperature, and light source with the wide shots. Usually a matter of diffusing and bouncing.

Just buy this book:


It's the most basic book out there and also the best. And despite being basic 99% of us could learn a lot from it; it goes over composition, aperture, frame rate, color temperature, coverage, etc. in the most basic but useful terms I've ever seen.
