Lenses / Re: Fast lenses at a crossroads?
« on: January 20, 2015, 02:08:11 PM »
1)  Making a lens as wide as 11mm with a pretty big zoom range also fast would be very, very difficult.  It would probably double the price, if not more.  The Nikon has a much longer wide-end and thus a much smaller zoom range (1.7 versus 2.2).
2)  Canon is making new, fast lenses.  70-200/2.8L IS II, 35/2IS, for example.  Sigma is as well with the Art series of primes and the 18-35/1.8 for crop.
3)  An f/4 zoom on full-frame is still exceptionally separated from a cell phone camera with a 1/3" sensor and an f/2.4 prime.  Around four whole stops separated, in fact.

These 70ish% numbers of in-focus shots for someone running slowly toward the camera just don't seem right to me.  I tend to get high 90s for that on my decade old 20D and 5D even shooting at f/2.8 and even zooming while shooting.  I'm planning to buy a 7D Mark II to improve on this, not degrade it.  For example, these were all shot on the 5D and 70-200/2.8 at f/2.8, I was zooming while she was running, and they are all in focus.

I have often framed to crop with the 15mm fisheye, and I remember seeing a very cool wedding image by Joe Buissink, he shot it with the 14mm and insisted he had needed to use that lens. The couple were in the bottom of the frame with fireworks bursting in the sky above. It didn't make sense to me until he showed the original file, the couple were actually standing on the roof of a van and they were just below the frame center pre crop, so when it was cropped they had no distortion but he had the fov to include the fireworks too, it was a perfect example of imaginative pre visualization and mitigation of ultra wide projection distortion.

There's a slider for that in Lightroom.

Yes and that slider is so generic and focused on rectilinear corrections it is all but useless most of the time for me. I do highly recommend a little plugin called Fisheye Hemi, it is the only ps plugin I use regularly, though the newer ps lens field corrections are so powerful even it has become nearly obsolete. The only other player in the game for high quality corrections is the dreaded DxO, their anamorphic corrections are pretty amazing, and very time consuming to replicate well in ps.

Well, that's for something else entirely.  For that I recommend Hugin and all of its many projection and shift transformations including General Panini.

12:00 - the EVF doesn't work when shooting in burst?  How does that not make it into the cons section?  How does that even make it into a released camera, for that matter!

That would be more than a show stopper for me, that would be an instant door stop.

By the way, Lee Jay, thanks for the link to the DIY pano head. I'm a tinkering fool that always likes to see if I can do it myself cheaper, better or at all. :P

If you have heavy equipment, or want a stiffer system (these bars are really stiff - almost as stiff as 1" square solid bars), it's pretty easy.  They make them in 1.5"x1.5", and they make 2x1 and 3x1 versions.  So, I made mine 1"x1", but you could make yours as big as 4.5"x1.5" or even bigger if you want, like 3"x3".

And everybody complained about the price if 24-70LmkII and lack of IS, but I don't see price dropping that much - because it IS the best 24-70 in every mount. Bought one, didn't regret it.

I wanted one.  Because it doesn't have IS, I didn't buy one or consider buying one, and I never will.  I have too many 1 second to 1/4 second shots on my 24-105 to give up the IQ that goes with being forced to shoot at three stops higher ISO because of this glaring error.

I have never once thought my 24-70 2.8Mk2 needs IS. Does all photography before the advent of IS suck? Technology may help your work but it isn't necessary. You are the greatest piece of gear.

Which would you prefer, an ISO 3200 shot or an ISO 25,600 shot?


I'd prefer carrying my tripod. For static subjects and  slower shutter speeds I wouldn't reach for IS. I do find IS useful with longer focal lengths BUT when image quality is a priority then I carry tripod - it allows you to turn that 3200 down to 100. It is "a must" photographic tool and is a must when image quality is a must.
Each to his own.

Most of what I shoot can't be shot with tripod or is in places where tripods are not allowed.  I own many tripods but they are largely impractical tools for almost everything I shoot or because I can't carry them where I'm going.

And as for "success", whether you take that as an insult or not is up to you, my definition of success is a sharp print corner to corner at 30"x40" or larger with good lighting and composition. Good luck trying to print a handheld panorama at sizes as large as that and not have them come out looking like crap.

Yeah, that's really, really easy to do.  I have four 42x28s near me at this moment, and a 36x12 (360°x120°) on the wall right in front of me, all taken handheld, with the last one taken while standing in a tiny two-person service lift 440 feet off the ground suspended by nothing but cables.

Yeah its easy to do, that's why tripods were invented, that's why camera manufacturers invented IS, and why all other forms of camera stabilization were invented. Because its easy to hold a camera for a picture.......much less a panorama.

It's much easier on a panorama than on a single shot.  Much.

Cheaper components....10 years later...in what world? With the rise of commodity prices and inflation that is a laughable statement.

They're made using more efficient processes now, and they're more popular and thus there have been economies of scale.

"Success" is certainly a relative term, and judging by the pictures that are also available through the link you provided, I would say my standard of success is wildly different from yours.

Ah, yes, the argument of someone without an argument ("I don't like your pictures").  It's highly likely that I won't like your images either, since I like essentially zero landscape images.  So what?  That site is almost 10 years old anyway and most of the shots I've taken with my setup are 360x180 immersive movies.

A panorama head is really a very unnecessary thing unless you have very close subjects.  I've taken hundreds and hundreds of panoramas handheld.

I like this one.

I'm not completely sure about the math, but at 24mm I believe you would have to make a multirow panorama, and in order to that competently and eliminate parallax you would need something elaborate like a Really Right Stuff Multi-Row Pano Elements Package which will run up to $915.

I built my own, very easily, for under $50.

Uh huh, how'd you pull that off?

Sorry but your home brew doesn't come close to the strength or precision of the RRS set up. Good luck leveling and setting everything up multiple times for multiple angles on a scene in a time constrained event like a sunrise or sunset.

I will give you credit, YOU made it for $50, so have a cookie to celebrate, however the average household does not have the tools to make this as you did, so the average household could NOT make this for $50....And this isn't bringing up the issue of that you made that in February 2005. I seriously doubt all those components are the same price as they were 10 years ago.

Also I hope you aren't shooting outdoor panoramics with that neck strap attached like you have in that picture. Camera not on the apex of the tripod + your home brew + wind hitting the neck strap = blurry shots.

Components are now cheaper.

I have used this quite successfully many times without issues.  Leveling is largely irrelevant since the pano is going to be processed anyway.  Regardless, I have a bubble level on it.  I've had no trouble with it supporting a 5D+70-200/2.8.  When it's windy, I just wrap the neck strap around it.  And it disassembles and folds up into a little zip top bag.

Why do you need an IS on a Wideangle, anyway? With a lense of this focal length you need not more than maybe a native 1/20 to freeze a picture... what do you want to capture on 11mm, except of architecture, nightsky or landscapes? Both would be better on tripod.

I recently took a couple of cave tours.  It's very dark, and I was shooting with my 15mm fisheye on full-frame.  To get the best IQ I was trying to keep ISO to 1600-3200 which was giving me 1/4th to 1/6th of a second at f/2.8.  Tripods are not only not allowed, but would be totally impractical even if they were due to slippery, wet, uneven ground.
