Stepping Rings Guide

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

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:

13mm
21mm
31mm
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
Compact

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

Laowa Shift Converter Nikon AI to Sony FE

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.

You can find more info from the UK distributor here Laowa lenses

How to photograph snowflakes

An amazing selection of snowflake macro photos and a article showing how to photograph snowflakes can be found on Alexey Kljatov’s ChaoticMind blog

If you have an SLR you can reverse your lens on the body using a reverse adaptor, or reverse a lens on a lens using a coupling ring (which has filter threads on both sides), or use extension tubes, close up lenses, macro lens or bellows. We have all these available on PhotographyAttic. If you cant find what you want contact us with specific requests

Measurements of a BPM Bellows Mount

The BPM bellows system around in the 70s was a versatile system with mounts to accommodate most camera and lens fittings. But it wasn’t the only one. The likes of Soligor, Hama, Russian, Kenlock and others made similar interchangeable systems, but with their own system of mounts. Im not sure which are interchangeable between bellows makers, but maybe the anatomy of a BPM mount may help you find out if the bellows you have can be used with a BPM mount.

David Noton and Joe Cornish discuss grad filters

There’s an interesting series of videos appeared that were produced by Lee Filters with conversation between the revered landscape photographers, Joe Cornish and David Noton. Epsiode 2 sees them discussing the changes digital photography has made in capturing the moment, and why they still use graduated filters. It’s not like the usual manufacturer produced media as there’s no mention of Lee filters, and well worth a view.

The Selfie explosion!

Where ever you go these days you will see people in beautiful or historic locations with their cameras pointing at themselves rather than at the scene in front of them. The rise of social media is the cause. And our need to tell people where we are, what we are doing, what we are eating, in the form of a photograph – the selfie!

In the past photographers would set up their camera pointing back at themselves and activate a timer. This would give the photographer 10 or 12 seconds to go back in front and adjust his/her clothing and posture before the camera shutter triggered. Smile!

But as cameras were added to mobile phones, along came a new breed of photographers who didn’t know what a tripod was and hadn’t a clue about the self timer mode. And as the numbers grew, so did social media, and so the new photographers just turned the phone around and photographed themselves. And then phone manufacturers adapted, so the lens appeared on the front and back of the phone and the rest is history. We now have a deluge of people taking photos of themselves. And we have manufacturers and innovators scratching their heads to come up with products that satisfy this need to photograph ourselves. The most popular gadget has been the selfie stick…an extendable pole with a phone mount on one end and a hand grip on the other.

But this method, like hand holding, always means the camera is connected to the body and sometimes the results show with an awkwardly extended arm. That’s why I still prefer the older and more traditional self-timer option. And you can get an app for your phone that adds a self-timer. All you need then is a minipod to hold the phone…unless you rest it on a table or shelf. Check out the minipods and supports on Photographyattic: Tripods and other camera supports

One of the most adventurous selfie products I’ve seen is the Air Selfie…recently announced with a pre order offer price of 260 Euros.

The AirSelfie is a pocket-size camera with a turbo fan that propellers to thrust the camera up to 20 meters in the air. It connects with your smartphone so you can take 5 MP HD photos or video of you and your friends from the sky. Possibly a little crazy price for most, but no doubt we will be seeing more aerial selfies in the future…especially when the Chinese copy the idea and knock them out on ebay for 39 dollars or so.

Why Hoyarex filters are often scratched

The Hoyarex filter system was really good: high quality filters.. Great variety of options in the range. Some glass filters. Solid holder. And a really useful rubber hood. But the Hoyarex System had a big flaw! And that has become evident over the years as more and more filters become scratched.

It’s not due to use either! These scratches occur when the filters are stored in their plastic case. The resin filter catches the edge of the case, which usually bends a bit in the middle. So after being jostled around in a camera bag the rubbing effect causes the resin to mark or scratch.

So here’s a tip to prevent further wear. Buy a packet of lens tissues and wrap one over the filter at the top end that sticks out of the case. Then the filter wont get rubbed. You can use toilet tissue, but a lens tissue is softer and has no fibres that will come off and cause dust problems.

Hoyarex Skylight 1B filter

The Hoyarex Skylight 1B filter – cat number 011 – is one of the most valuable filters in the Hoyarex range, yet is often overlooked, because its not a special effect filter.

But this underused filter will do two things to ensure your photography improves.

Firstly, and most importantly, the filter is a lens protector. The Hoyarex system is made so that when a filter is placed in the back slot it removes any possibility of dust reaching the lens. So if the holder is left on with a filter inserted the lens wont get dust falling on the surface or scratches. The skylight is the obvious choice as it has no special effect value. It’s also one of the few filters in the Hoyarex range that’s made from glass so optically very good.

But the filter has another use. A skylight filter has a very slight pink tint that has a warming effect when shooting in hazy days, so landscapes can be photographed with slightly more clarity.

Using the filter in the back slot near the lens means there still another slot free for a special effect filter when you want to add a graduated effect, sepia tone or spot for example. Photographyattic has the Hoyarex 011 Skylight 1B glass filter for sale here
