Large format photographers using cameras with bellows have always had the luxury of being able to adjust the lens and/or sensor plane so they are not parallel. This technique is performed to alter the plane of focus. While a conventionally parallel set-up provides front to back sharpness from a focus point parallel to the sensor, the adjusted lens, swung or tilted, places the focus plane at a different angle. This is a very useful technique for landscape photography, allowing sharp focus from close range to infinity, even at wide open apertures. But it’s also incredibly useful for macro photography. With this in mind Photography Attic has taken a set of BPM camera bellows and modified them to create a versatile set of custom bellows with tilt, swing and also shift options.
The bellows lens and camera platforms are individually mounted on a pair of small ball & socket heads which can be attached to a straight bracket like the one you would use with a flash gun. You can then slide the ball and socket along the flash bracket to extend the bellows increase magnification. And then tilt the front or rear panel to create the new plane of focus.
Here’s an example of the tilted bellows in action. A small 25mm pocket watch has been photographed at an angle. Rather than head on and parallel to the camera lens. The lens was then tilted on the camera bellows set up and as a result the widest aperture of f/2.8 can be used with full front to back sharpness. As a comparison a second shot was taken with the lens set conventionally parallel to the film plane. Notice how the sharpness falls off to the rear.
Another option is to use the swing feature. Here the lens is angled in a clockwise or anti clockwise direction to provide sharer front to back focus on an upright subject.
You can also adjust to provide a combination of both tilt and swing when the subject is not horizontal or vertical.
This process is technically known as the Scheimpflug Principle. If you would like to lean more check out the wikipedia page here: Scheimpflug Principle

An extremely rare and very early double-stroke, black paint Leica M3 will go under the hammer in a sale of Photographica by Chiswick Auctions on Thursday 14th November, 2019.
This camera was delivered to the Magnum Photo Agency in Paris in 1958. Factory records show only 90 of these pre-series cameras were sent before the first official batch of black M3 rangefinders in 1959. It’s not known how many others are still in existence.
The majority were delivered to Sweden along with individual deliveries to Paris, New York and Germany. The serial number records it as the 15th black paint M3 camera to have been produced, and the second earliest example to be offered at auction. (The earliest example, the second of the batch, sold in 2014 for £320,000 in Hong Kong). This model has a conservative estimate of £60,000-£80,000, but, due to its popularity and rarity, it is expected to achieve much more.
A teleconverter, also known as an extender, is a camera accessory that attaches between the lens and body of an interchangeable lens camera. They were made for 35mm and medium format cameras and are hard, if not impossible, to find for micro 4/3rd. That said this article is using one on a micro 4/3rds fitted with a Pentax K adaptor.
Whats does a teleconverter do?
A teleconverter increases the focal length of a lens by the number of x. The most common is 2x but models have also been made in 1.4x, 1.5x and 3x. With a 2x teleconverter your 300mm telephoto lens becomes 600mm.
What are the advantages of a teleconverter?
The main advantage is size and cost. A teleconverter and one lens takes up much less space than two lenses And it’s much cheaper to buy a teleconverter than a second lens.
Another advantage is the closest focusing distance of the lens doesn’t change when a teleconverter is attached so the magnification is doubled with a 2x from the same distance.
What are the disadvantages of a teleconverter?
The teleconverter adds a few more layers of glass for the light to travel through so there’s chance the image quality will be degraded. This is more noticeable on cheaper models where contrast can suffer as well as added distortion and reduced sharpness.
The teleconverter reduces the amount of light reaching the film/sensor by the same factor as the magnification. So a 2x converter loses two stops of light and a 3x converter loses three stops of light.
Can you use more than one teleconverter?
Its possible to add several teleconverters in a stack. Sharpness decreasing and light loss increasing with each one added. In this article Stacking five 2x teleconverters Petapixel stacked five teleconverters onto a 300mm lens to get a huge 9600mm telephoto.
A couple of test photos with a teleconverter
Below are examples of two subjects taken with the illustrated combination above – an Olympus OMD EM5 MkII with a 50mm f/1.4 Pentax lens and a budget priced Ozeck 2x teleconverter. The left photos are without the 2x teleconverter and the right hand ones are with the teleconverter. The map is taken at the closest setting of the lens, and the city view is with the lens at infinity. The bottom pair are highly cropped pics from the city scene. You can click on the four top pics to see the full size version.
For those viewing on a mobile device 1, 3 and 5 are without teleconverter and 2, 4, 6 are with teleconverter
As you can see the converter loses contrast, but sharpness is not as bad as many people have made out over the years, and a converter is certainly a good idea if your budget is tight.

There’s a video doing the rounds at the moment titled Leon The Professional. It’s being shared by photographers who’re impressed by the featured photographer’s home made “shooting” accessory. The gent in question has adapted a wooden rifle stock to the bottom of his camera to create a comfortable hand holding gadget for long lens shooting …in this case bird photography.
Photographers who’ve been around before the digital age will remember this type of gadget is not new.
Back in the 70s they appeared in a kit from Russia called the PhotoSniper.
This was a Zenit camera with a chunky 300mm telephoto and a very realistic rifle grip below. Supplied in a metal box style case, at a very good bargain subsided price. But was seen as specialist gear as heavy and cumbersome for the majority of photographers.
Way before this in the 1950s-60s Novoflex had added a handle grip to the base of their long lenses in a gadget called the Pistol Grip Follow Focus. Available in 400mm, 600mm and 640mm with a 560mm joining the range in the 70s. This gadget focused the lens when the trigger was squeezed…later models had a push pull action to focus.

In the 70s-80s thanks to the popularity of the SLR and rise of camera accessory brands several budget Japanese/German products appeared from the likes of Rowi, Hama and Kaiser that could be attached to the base of your 35mm SLR to convert into a rifle grip. The Kaiser Kamera – Schulterstativ 6005 Rifle Grip was one such example.
These were light weight and had a cable release attached to the trigger to make rifle shooting simple. Camera Retailers Jessops and Dixons also sold rifle triggers for under £20.
And throughout the history of the 35mm camera, manufacturers have produced trigger grips that attach to the base of the camera to provide alternative and more comfortable ways of holding and firing the shutter. These are just a simple hand grip shaped handle which are much lighter and far less bulky than the rifle grip.
There’s a really interesting article about photographer John Duder going back and experimenting with filters he never got around to using in the 80s over on ePHOTOzine: Experimenting With Filters From the Eighties I Have Never Used – Come Check Out The Results
Also interesting that we’ve got many of the filters he used here on PhotographyAttic. check out our Cokin A-Series section and the Cokin P-Series
A stepping ring is an adaptor that screws into the front of your lens to change the filter thread size. The idea is you can make one filter fit a number of lenses with different filter thread sizes by attaching a stepping ring in between the filter and the lens.
Their are always two numbers on a stepping ring. The filter thread size of the lens, and the filter thread size of the filter. They always start with the lens filter thread size first. You use a step up ring to attach a larger filter on to a lens with a smaller filter thread size And you step down to use a smaller filter on a lens with a larger thread.
So a 49-58mm stepping ring is a step up ring and will let you screw a 58mm filter onto a lens with a 49mm thread (see pic above). While a 67-55mm stepping ring is a step down ring and will let you screw a 55mm filter onto a lens with a 67mm thread.
Generally its better to use step up filters on wide angle lenses to avoid vignetting where the smaller filter encroaches into the edges of the frame. A step down filter is better used on telephoto lenses.
Here at PhotographyAttic we have a wide range of stepping rings from a number of brands. And we’ve reduced the price so most unbranded ones are £2.00 and ones with brand name are £3.00. Buy here: Stepping Rings for sale
Extension tubes are tubes without any optical elements that you place between the camera and lens of an interchangeable lens camera. They extend the lens so it can focus closer, giving the lens macro capabilities. Some have full automatic couplings so the camera can continue to be used in all its auto and program exposure and focus modes. Some lower priced ones have no couplings, so the camera needs to be used in manual.
Tubes are often sold in sets of three. The set illustrated above has 13mm, 21mm and 31mm extensions, and these can be attached in any combination giving a total of seven different extensions:
- 34mm (13mm+21mm)
- 44mm (13mm+31mm)
- 52mm (21mm+31mm)
- 65mm (13mm+21mm+31mm)
Here a set of three tubes can be seen attached to a Nikon digital SLR camera.
This photograph of a British one pound coin was taken using a nikon camera with a 55mm lens set to infinity and an extension tube added. The smaller coin on the left is with the 13mm and the coin on the right is with the three tubes attached giving 65mm extension. The lens was at f/2.8 to show how shallow depth of field is. When using tubes you either need to use a very small aperture or shoot the subject parallel to the CCD or film plane. Here the coin was at an angle so only a shallow strip across the centre is sharp.
Advantages of using Extension Tubes
Low cost macro
No optical degradation
Disadvantages of using Extension Tubes
Limited magnification variations
Fiddly changing between magnifications
Taking lens off increases risk of dust intrusion
We have a selection of extension tubes in different camera fittings
This seems like an interesting gadget to put on a Nikon SLR and convert the Laowa 12mm into a shift lens. ideal for architecture photographers.
The converter is designed exclusively for Sony FE lens mount and fits on cameras with a Nikon AI mount. It has a 1.4x magnification so the 12mm lens becomes an effective 17mm focal length and has a 1-stop aperture loss
With the 360g converter in place you get a +/- 10mm Shift
Combined cost of the 12mm and shift converter is about £1170.
