Fisheye Pictures

15th September 2022

With A View up to 180 Degrees

The fisheye lens is an interesting accessory. I have one that zooms from 8mm to 15mm. At 8mm the lens can take in a full 180 degree view. At 15mm it has a 175 degree view.

At the 8mm setting my lens produces a circular image and at 15mm the image is full frame. Regardless of the zoom setting the images are distorted and produce a panoramic effect. You can often recognize one of these images by seeing that straight lines appear curved.

I’ve used this lens both in the field and in the studio and get a kick out of some of the fascinating results.
 
 

Full Frame Mirrorless

Although I have been a longtime user of mirrorless cameras, I’ve been sitting on the fence about moving to a full-frame model. What was holding me back was my reluctance to make a sizable investment for a new set of lenses.


This past February while attending the Wedding & Portrait Professional Conference & Expo in Las Vegas, Sony introduced a new camera – the Alpha 7 III. In case you’re curious about it, see my previous article about the WPPI Expo here.

A couple of features of the 24 megapixel A7 III caught my attention. First was the camera’s autofocus system. Using 693 phase detection AF points focusing was fast and accurate. Second the camera’s Eye AF which identifies and tracks the subject’s eye as the focus point. Third was its high continuous shooting speed – up to 10 frames per second. And forth was the comfortably adjustable LCD screen. And I saw that the A7 III had dual SD card slots. I spent about 30 minutes inspecting the camera and bouncing questions off of Sony rep Dave Rhodes. I left the expo with a very positive opinion about Sony’s brand new model.

After returning home from WPPI, I pre-ordered the camera with a 28-70mm lens. Along with it I ordered an accessory that would allow me to use my collection of Canon lenses with this new model. This device is the Metabones Smart Adapter.


Last week Sony released the first batch of A7 IIIs and my order arrives by courier, but due to my workload I wait a few days to open it. When I finally free up some time I find that the package contains the body, lens, USB charging cord, shoulder strap and instruction manual. Strike 1 on Sony. I see that the package does not have a battery charger. Instead I have to use a USB cord to connect to the camera body to charge the battery.

Now I think that I’m ready to take a few shots so I attach the lens, insert the battery and a blank SD card and turn on the camera. Strike 2 on Sony. The battery is not charged so I cannot power on the camera. Disappointed, I unwrap the USB charging cord only to find that there isn’t an A/C adapter for the cord. Strike 3 on Sony. It would be nice for Sony to al least supply an A/C adapter for the USB cord.

After striking out, I have to take a break. I hunt around for an A/C adapter and then proceed to charge the battery (in camera) for a couple of hours. After the battery is charged, I head outdoors to take a few shots.

While there isn’t anything remarkable about the photos, I want to see the camera shoot still, close auto focus (branch), action (runner), high frame rate (duck) and auto white balance (indoor).


I’m right-handed. The camera grip feels solid. Overall the body is compact without miniature features. The electronic viewfinder is bright and crisp. The LCD screen is adjustable making it easy to compose your shots whether they are overhead or low to the ground..

I like this camera’s dedicated exposure adjustment dial. A control wheel on the rear and another on the front are useful for changing exposure combinations. There are four buttons that let you customize the settings to your preferences. For those in a hurry to share photos, one of the controls lets you send images to a smartphone by Wi-Fi. And compared to my other full-frame DSLRs, the A7 III is noticeably smaller and lighter.



To be honest, I would not have purchased the A7 III had not the Metabones adapter been available.

This accessory allows me to use my full-frame Canon lenses with Sony full-frame FE-mount bodies including the A7 III. Having read dozens of reviews of the Metabones adapter beforehand, I was convinced that it was the only way for me to afford a new A7 III without having to buy a new set of lenses.

As part of checking out this new camera, I tested all of the Canon lenses in my collection with the A7 III using the Metabones adapter.

I was pleasantly surprised. The adapter worked with all of my lenses. Additionally the lens information (ID, shutter speed, f-stop, focal length) was transferred to the images’ EXIF data (two lenses were incorrectly identified).

Below are images made using those respective lenses.

8-15mm F/4L Fisheye @15mm


17-40mm F/4L @17mm

17-40mm F/4L @40mm

85mm F/2


100mm F/2.8 macro

Sigma 20mm F/2

100-400mm F/4.5-5.6L @100mm

100-400mm F/4.5-5.6L @400mm

All of these photos were taken from a distance of about eight feet except for the two 100-400mm photos which were taken from a distance of about 16 feet. In short, the Metabones adapter lets you use Canon EF-lenses on Sony FE-mount bodies.

Sony E-mount lenses (designed for the smaller APS-C size sensor) can be used on the A7 III. My E-mount 18-200mm lens worked perfectly. However using an E-mount lens reduces the image resolution from 4000 x 6000 pixels to 2624 x 3936 pixels.


 
 

One neat feature that I am going to use for portraits is coined Eye AF. Long ago I was taught that for portraits it is important to focus on the subject’s eye. With Eye AF activated, the camera identifies the subject’s eye and makes it the main focusing point even if the subject moves. Eye AF worked well with the several subjects that I photographed.

I should mention that there’s an app on my iPhone that lets me grab images from the A7 III. The app is called PlayMemories Mobile and lets me download the images (JPGs only, not the raw ARWs) from the SD card to my iPhone. Having used the app with other Sony cameras previously, I’ve found it to be easy and very reliable.

I should also mention that PlayMemories Mobile also lets me record location information for the images. Using the smartphone’s GPS capabilities, the app sends the location coordinates via Bluetooth to the camera as it is capturing the images onto the SD card. Again, in my short time using this feature, it worked reliably. Bravo Sony.

I use the classic version of Lightroom to perform most of my image editing. To be exact, I’m now using Lightroom 6.14 but it’s my understanding that Adobe will not be making any further upgrades to this version. Therefore it’s unfortunate that I am unable to edit the raw ARW files with my copy of Lightroom without performing an extra step. Luckily I’ve found a way to fool Lightroom into believing that the camera’s raw ARW files were created with the previous generation Sony A7 II camera. Still this “fix” is an inconvenience before editing with Lightroom.

Despite my initial frustration (lack of a charger, uncharged battery, etc) out of the box, I remain very positive about its impressive features and performance. Having spent a few hours “playing” with this new mirrorless, I’ve used only several of the features that first attracted me to this camera. There are many more that I plan to become familiar with and use. Additionally, there are a large set of features that should be of interest to the movie enthusiasts. Admittedly, I’m not deep into moviemaking so I will cede the reviews on this aspect of the camera to other photographers.

In the mean time, if you’d like to learn more about this new model, Sony has an extensive description of the Alpha 7 III features here.

The suggested retail price of the A7 III is $2000 for the body or $2200 for the body with 28-70mm lens and is now available.

PhotoPlus Expo – Sony a7

05th November 2013

Full Frame Mirrorless Interchangeable Lens Camera

At this year’s PhotoPlus Expo, I made it a point to visit Sony’s booth to have a quick hands on their newly announced Alpha 7 camera. But first, here’s a little background that may help to explain why I take such an interest in the a7.

In 2010, Sony introduced the Alpha A55 with its unique translucent mirror. The non-movable mirror enables Sony to pack many innovative features into a space-saving SLT body that are missing from conventional DLSR cameras – accurate and continuous autofocus, real time electronic viewfinder, sweep panorama, multi-frame noise reduction, more. Since then I’ve been a user of two models – the A55 and a more advanced A65. Both produce excellent images. And since they are considerably smaller and lighter than the competitor’s equivalent models, they are less burdensome in the field.

These two SLTs cultivated my fondness for lightweight equipment. So I was very intrigued when I learned about Sony’s NEX series of compact camera. With an APS-C sensor, a NEX camera body is half the size of a DLSR yet accommodates interchangeable lenses owing to its mirrorless design. I soon acquired a lower-end NEX 5 to see if it met my requirements. I found it has image quality but I was not comfortable using the LCD finder with longer lenses. I then purchased the NEX 7 that sports an electronic viewfinder. Since then this has been my camera of choice owing to its excellent image quality, innovative feature set, compact lens size in an extremely lightweight package.

Several weeks preceding the PhotoPlus Expo, Sony announced the Alpha 7. It’s a direct descendent of the NEX series. Yes, it has a full frame sensor but its mirrorless design has been proven by several generations of the APS-C size NEX cameras.

You can see the thinness of the camera body with 35mm lens attached.

Specs: 24MP sensor, hybrid phase detection/contrast-detection autofocus, bright 2.4MP electronic viewfinder, articulated LCD, full HD video, Wi-Fi and NFC connectivity, E-mount and full E-mount lens compatibility.

I asked Meagan, the Sony rep, if the very compact E-mount lenses are compatible with the a7. She told me that they can be used but the view is shrunk to cover only the central 16MP of the sensor.

For the a7’s larger sensor you’ll have to use one of the new Full E-mount lenses: FE 28-70mm f/3.5-5.6; Sonnar 35mm f/2.8; Sonnar 55mm f/1.8 and Vario-Tessar 24-70mm F4. Also coming is a Sony 70-200mm G f/4 lens for early 2014.

Meagan says that delivery of the a7 begins December 1. Price is $1699 for body only and $1999 with the 28-70mm f/3.5-5.6 lens.


 

 

I am impressed with the small size of the a7. With the 28-70mm lens attached, the package is amazingly small and lightweight. While I wasn’t able to examine my test shots in detail, I’m confident that the full-frame sensor will delivery excellent images. In fact, I understand that Sony supplies this same sensor for use in Nikon’s D600 full frame DSLR.

So I remain in a quandary. Should I move from my very comfortable NEX 7 to this new full-frame a7?
