Camera Stability and Long Lenses

January 29, 2014 G Dan Mitchell 5 Comments

I responded to a question somewhere else and thought that it might be useful to share the response here, too. A photographer asked some questions about using long focal length telephoto lenses for landscape photography and how to deal with the issue of camera/lens stability, bringing up related questions about things like live view modes, mirror lockup, image-stabilization, and so forth. Here is what I wrote in response…

If you are shooting landscapes from the tripod…

Do use live view – it is the mode that introduces the least amount of shutter vibration.
Either mode 1 or 2 will perform essentially equally well when it comes to shutter vibration. (In both cases, there really isn’t any shutter motion vibration before the exposure since it is initiated electronically.
If you use a remote release (and you do, right?!) then there is no reason to use any delay setting on the camera to avoid vibration. (Many cameras have settings for 2 second or 10 second delays – mostly there so you can run and get in the photo, too!)
Mirror lockup is irrelevant in live view. The mirror is up by default in live view. To be even more explicit, live view and MLU are mutually exclusive modes – they cannot be used at the same time.
After touching the camera, moving the tripod, etc., wait a few seconds for vibrations to dissipate before making your exposure. I think that 2-3 seconds is sufficient, though some folks will claim that even longer might help.
Speaking of this, I would tend to avoid using either auto-focus (AF) mode when making landscape photographs with such a long lens. Either can introduce some amount of vibration to the system, but especially the mode that momentarily flips the mirror down, auto-focuses in the usual manner, then flips the mirror up to make the shot in live view. I prefer to manually focus at 10x magnification. If you must autofocus, do so before switching to live view mode, and then turn AF off before making the exposure.
Realize that the large area of these big lenses, combined with their very long focal lengths and great magnification, make the system far more susceptible to vibration from air movement. Even relatively weak breezes can create enough vibration to create a bit of blur and soften the image. Continue reading Camera Stability and Long Lenses →

Trees and Granite, Morning Light

Brilliant morning light shines on subalpine trees and receding granite ridges, Kings Canyon National Park

Back in September of 2013 a group of four photographers headed off into the backcountry of the Kings Canyon National Park Sierra Nevada for nine days. (It occurred to me today that between the four of us, we have well over a century of experience in these mountains!) We crossed a Sierra crest pass at close to 12,000′ feet, another non-crest pass that was even higher, and then landed in a lake-filled basin where we set up camp at 11,000′ for most of a week. This basin is off the main through trails and the trails that do go here essentially dead-end, so there aren’t a lot of visitors here. Because we remained in one spot we were able to get to know the landscape more intimately, looking more closely at places we might have missed if we had just been passing by on the trail, and returning to photographic subjects more than once in changing conditions and light.

Up the valley from our camp was a series of sub-alpine lakes, surrounded by the quintessential High Sierra landscape of glaciated granite, tiny meadows, small trees, and ponds and lakes. I developed an almost daily loop up towards the upper lake, coming and going by different paths, and I began to get a better sense of the personality of this place. I made this photograph by climbing up a granite spine to a high point where the terrain flattened a bit and afforded a view of the surrounding valley. This photograph was made in the morning, when low angle light was streaming across the top of the farther ridge and backlighting the trees in front of me.

Photographs: New York City

Room 160, Metropolitan Museum of Art

Visitors pass through Gallery 160, Metropolitan Museum of Art, New York

It was a cold and rainy day in New York. For the most part we were fairly lucky with the weather when we visited between Christmas and New Years, with mostly fair though cold weather. But we finally encountered a day on which it was not going to be pleasant to travel around a lot on the subway, so we decided to head to the Metropolitan Museum of Art. Apparently about half of the people in New York City had the same idea! Although we arrived reasonably early, there was already a large line of umbrella-carrying folks standing in line, and once inside we found crowds everywhere. We were obviously not the only people to seek shelter in indoor activities. (For the most part the crowds in New York City don’t bother me too much, but on our subway trip back to our hotel after the museum visit I encountered the worst jam-packed subway that I had run into… and realized that this is not a place where I’m ever likely to live. Visit? Yes, and with pleasure!)

We have visited several times before, so we are starting to be familiar with a few sections of this huge museum. We visited a wonderful exhibit of Julia Margaret Cameron photographs (and realized how much of photographic portraiture she already understood more than a century ago) and a small exhibit of photographs from the past 40 years (some of which I liked a lot and some of which leaves me cold). We also wandered a bit, and when we entered this room not far from the main lobby, I spotted a stairway and though that it would be interesting to photograph the room from above. I was intrigued by the lighting, the crowds of people walking in every direction, their shadows, and the large figure of the statue in the center of the room. (As I photographed, using a small mirrorless camera, a guard must have thought that I was shooting video – which is apparently forbidden – and he started yelling at me from the lower level! I finished my shots and moved on.)

Fujifilm X-T1 Digital Mirrorless Camera Announcement

January 27, 2014 G Dan Mitchell Leave a comment

Fujifilm has announced their new X-T1 Mirrorless Camera. The rumors regarding this new camera have been rampant for the past few weeks, and here is what we now know:

16.3 MP X-trans 1.5X cropped sensor
ISO 100-51200
8fps continuous shooting
Improved hybrid AF system incorporating contrast- and phase detection methods
Improved manual focus with digital split image and focus peaking
Faster, higher density, and larger electronic viewfinder
1080p HD Video
WiFi
Expanded manual control dials for shutter speed, +/- 3 EV exposure compensation, ISO, aperture (on many lenses), and more.

A number of features get my attention. My Fujifilm X-E1 works well at high ISO values, but this camera appears to take the much farther extending the lowest ISO from 200 to 100 and the highest all the way to 51600. The specifications and early reports on the web suggest that the AF system has been significantly improved, even beyond those improvements on the X-E2. The added manual controls are going to help a lot for the sorts of photography that many of us do with this sort of camera, where we need to change settings quickly and without going through menus. There are lots of other improvements, large and small, too numerous to mention here.

I’m very interested in this camera. My X-E1 is a wonderful little picture-making tool that complements my larger DSLR system – and the X-T1 sounds like it has been designed to significantly improve on this effective concept. (There is a very good chance that I’m going to get one.)

The camera is available for pre-order now at site sponsor B&H:

Fujifilm X-T1 Mirrorless Digital Camera Body – $1299
Fujifilm X-T1 Mirrorless Digital Camera with 18-55mm lens – $1699
