My Single Lens Story

<br /> My Single Lens Story<br />

Searching For More Millimeters


Nature and outdoor photographers will tell you that you can never have too long of a lens – the more millimeters, the better! I’m one of those photographers.

For me a single lens that has wide angle settings for inclusive scenes and can zoom out to capture distant subjects is preferable to carrying multiple lenses. The lens that attracted my attention was an 18mm to 300mm zoom. However I was only able to find one made for APS-C sensor cameras.

My main camera has a large full-frame sensor with a resolution of 9504 x 6336 pixels. Luckily it can accept APS-C lenses although the sensor resolution is reduced to 6240 x 4160 pixels.

Here’s a small gallery comparing the relative image sizes when using the APS-C lens and full-frame lens. While these samples are not subjects from the outdoors I hope that they illustrate the concept of mm reach.



Below are side by side sample photos taken at various lens setting. The photos on the left were all taken with the Tamron APS-C lens. The photos on the right were taken with the Sony full frame lens.

Keep in mind that although the subject size is smaller on the right, there are more pixels available if you crop the image in post processing.

For me, the bonus in using the Tamron lens is the addition of reach up to 300mm which gives me the ability to capture more distant subjects from a single lens.


 

I just returned from a recent trip with my full frame Sony camera and the Tamron lens. The two photos below were taken from a distance and the extra mm’s gave me a more detailed images of the two birds.

My back was grateful too since I was weighted down with only a single lens instead of two lenses that could offer me the same range.

 


As a bonus I can use the new Tamron lens with my older and smaller APS-C size Sony A6000 camera.

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.

high speed frame rate

auto white balance
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..



convenient and customizable control

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.



135mm F/2L

35mm F/2

75-300 F/4-5.6 @75mm


75-300 F/4-5.6 @300mm

24-105mm F/4L @24mm

24-105mm F/4L @105mm


50mm F/1.4

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

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

24mm F/3.5L TS-E


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.
