The Final Word on Sensors

Derek Smith • 8 August 2022
For me personally a camera with an APS-C sensor is the sweet spot for size, weight, cost, and performance. An APS-C camera usually has a kit lens with a typical focal length of 16-50mm, equating to the 24-70mm typical focal length of a full frame camera kit lens, because the APS-C sensor is smaller than the full frame sensor, the focal length of a lens will be 1.5 times smaller (1.6 times for Canon sensors) to obtain the same field of view. 

For lenses I like to have a zoom lens of approximately 16-50mm, and a telephoto lens of 50-300mm, also I do like my fixed focal length lenses, these are called prime lenses, and a photographer can always use a “nifty fifty” 50mm lens, which in APS-C terms becomes a 35mm focal length, with a wide aperture of f/1.2 – f/2.0 for use in low light situations. Many photographers like a selection of prime lenses a typical trio of prime lenses would be 35mm, 50mm, 85mm in full frame terms, that’s 23mm, 35mm, 56mm in APS-C terms.

Nikon, has three APS-C mirrorless cameras, (which are termed as DX) the Nikon Z30, Z50, and the retro styled Zfc. DX Z mount lenses are as follows: 16-50mm, 18-140mm, 50-250mm, however for prime lenses only full frame are currently available, so not a bad start for a relatively new format. 

Canon has recently introduced the APS-C Canon R7 which appears to be a professional standard camera, and can be purchased with the RF-S 18-45mm, or the RF-S 18-150mm lens, which should be good for travel. Again, currently no dedicated RF-S prime lenses, but the RF 35mm f/1.8 macro, and the RF 50mm f/1.8 can be used on this camera. For wildlife photography the RF 100-400mm could be a good match for this camera. Now that Canon have chosen to introduce an RF mount APS-C camera, questions inevitably arise over the future of the APS-C M mount system of cameras, and lenses.

Sony has three APS-C mirrorless cameras the A6100, A6400, and the A6600. I fervently believe that Sony dropped the ball on their APS-C offering, considering the Sony NEX 7 was introduced in 2011, with the E mount 16-50mm, and the 55-210mm zoom lenses. The basic rangefinder design of the camera has hardly altered in 11 years!!, still not very ergonomic, in fact the NEX 7 had more controls than its A6000 successor. I used the Sony NEX 3N, the A6000, and the A6300 extensively for a number of years, the auto focus was amazing, possibly even bettering some modern cameras, but the lack of lenses, and poor ergonomics led me to leave the brand. Sony APS-C lens development stagnated, with the R&D development budget used to develop the full frame A7 series of cameras, and lenses. Third party manufacturers Sigma, and Tamron filled the gaps in the APS-C lens line-up early on, and only now is Sony beginning to fill the gaps. Placed alongside the A6100 though, the Nikon Z50, the Fuji XT30, and Fuji X-S10 APS-C cameras all represent improved handling and a better range of native lenses at a similar price point.

Fuji, well where do you start? Fuji X-E4, XT30ii, XT4, X-S10, X-H2S, all APS-C cameras plus a full range of native lenses, in my very humble opinion the king of APS-C. 

Images posted with this blog, Nuthatch taken with the Sony A7ii, and with the Olympus E-M5iii. The Bee, and Robin taken with the Fuji XT3.    

Clearly the full frame sensor has greater dynamic range, but photographic skills, use of lighting, and choice of lenses will best any advantage that can be obtained from a larger sensor. 

The answers to the “Summer Fun Quiz” 

A-Monica Olympus O-MD E-M5iii, with Sigma 30mm micro four thirds system at f/5.6
B-Heather Apple iPhone SE
C-Marika Fuji XT20, with XF50mm f/2.0 APS-C system at f/4
D-Ruby Sony A7ii, with Samyang AF 45mm f/1.8 at f/3.5 full frame system

My personal favourite portrait is Ruby, but I don’t believe that this is entirely due to the sensor. Ruby was positioned in the centre of the room, some distance away from an east facing window with net curtains diffusing the light, and the pose strengthens the image. Next favourite is Monica, this time positioned close to the window in full sun, choosing the f/5.6 aperture to control the light, the Sigma 30mm f/1.4 lens (60mm full frame equivalent) was my lens of choice for portraits on micro four thirds, strangely I never took to the 25mm focal length (50mm full frame equivalent). The portrait of Marika was taken with the Fuji XF 50mm f/2.0 lens (75mm full frame equivalent), this was my first outing with the lens, I enjoy the focal length, better than the 85mm full frame lens, the pose, and lighting could have been improved to create a more stunning image.

The LPA Battles competition was held last night at Axholme Camera Club, in Haxey Church Hall. I attended as the Louth Photographic Society representative, bringing the Battles prints with me. It was a closely fought contest with some excellent prints from Axholme, Barton, and ourselves. The judge for the evening was Steve Dormer, from Doncaster, and he was very relaxed in his judging of the prints, providing excellent critique on each print. At break time, Steve had held back a total of 13 prints for further assessment and award of higher points, Axholme, and Louth had 5 each prints held back, with Barton 3 prints. The attached photo shows all the held back prints on the print stand. At the end of the evening Axholme took 1 st place with, 266 points, Louth came 2 nd with 258 points, and Barton 3 rd with 251 points. As the prints were taken off the stand, one print remained, it was a Louth print titled “Sleeping” by David Whitehouse, this print was awarded 20 points, and the judge Steve was very taken with the image, well done David.

Good Morning All Last week members walked along the Swaby valley, we have done the walk before, but it is now very grown up with nettles, grass and brambles. Not put off Chris led us through the valley to Swaby, there were six of us plus three more who caught us up in Swaby. The butterflies we saw as I am finding out this year just don't want to settle but we did manage some photographs before returning and going for a drink in the Massingberd Arms. This week there is an LPA Battle at Axholme on Wednesday starting at 7.30, if anyone would like to attend, please email me for details or look on Axholme's website. We are not having a meeting in Louth this week, probably as well the way the football went last night and with the next match on Wednesday evening. Regards Graham

Last night our members enjoyed a visit to the Swaby valley nature reserve. We crossed over two fields from South Thoresby, then followed the course of the Swaby Beck chalk stream through the valley, the public footpath was bounded by dense vegetation that hindered our progress at times. There was plenty to see around the reserve, myriad butterflies flitted around in a very lively manner, making for difficult photography, I spotted several small grasshoppers, and soldier beetles in the long grass, I tried to photograph a ladybird, but it was gone by the time I focussed on the creature. It was a very enjoyable evening, with good friendly company, and our camera skills were needed for the macro photography, these are a few of my photos from the evening.

Good Morning All Last week's outing was re-scheduled due to a clash with a certain world cup match, the good news was a victory for England, however we intend to still hold the outing on Wednesday 22 nd July. I did go to the Festival of Flight at the Shuttleworth collection, Old Warden last weekend. It was too windy for some of the old Biplanes, but we were treated to a four-and-a-half-hour display featuring many planes that I had never seen fly before. The De Havilland Comet was built to compete in the 1934 race from Britain to Australia, only three were built and it's good to see it flying, the aircraft design was quite advanced for 1934. This week, Wednesday 8th July, we have another camera club outing to the Swaby Valley, meeting at 6pm. Swaby is just off the A16 heading from Louth to Skegness. Regards Graham

Last night’s Louth Photographic Societies outing to Kirkby gravel pits nature reserve was cancelled as some members preferred to watch some sporting gentleman by the name of Harry Kane. (Congratulations to the England team) The reserve is small, and simply laid out, a public footpath leads along a tree lined avenue to the river Bain at the back of the reserve. Historic sand and gravel extraction has left a large lake in the centre of the reserve, several ducks and waterfowl inhabit the lake and there is a bird hide on the shoreline. Returning to the road, there is a path running parallel to the road bounded by a hedge, insects of various types can be found in this area, damselflies, butterflies, and hover-flies are often prolific. Our outing to Kirkby Gravel pits is now scheduled for Wednesday 22nd July. Parking is on the verge by the roadside. Kirkby Gravel pits are fairly close to where I live, and it’s reserve that I often visit, these are some photos from a visit in July last year.

Good morning, All,  Last week at the club we had our monthly print competition, Trees and Open. There was a very good entry with a high standard of photography on show. Tony Gaskins was first in the Open and I managed a first in the trees, all the results are on our website and there is also a blog on the evening. This week, Wednesday 1st July, we are having an outing to Kirkby Gravel Pits, if we meet at 6.30 at the reserve, though you can arrive earlier as there are usually dragonflies etc around the entrance. If we walk straight ahead first, then anyone who arrives late can find us. I have struggled to find a map, but you can see the location on the Lincolnshire wildlife Trust website. Kirkby Grave Pits is also a good reserve for birds. Tattershall Road 1 mile south of Kirkby-on-Bain Woodhall Spa Nearest postcode LN10 6YN. Please note - postcodes are for the nearest registered address as we are unable to get postcodes for nature reserves.

A print competition was held last night with the categories of "Trees" as the subject, and "Open". Our judge for the evening was Gail Wrigg from Barton who did an expert job. The first category to be judged was the "Open" with the high standard of prints making the choice of top placement difficult, and Gail held back 9 prints for further evaluation. There were some chuckles from members around one of Richard Hildred's prints of wooden electricity poles titled "In my previous life I used to be one of them" an "in" joke from Richard, which totally baffled Gail. After the break Gail judged the "Trees" category, with 7 prints held back this time for awarding of higher marks, the beautiful colours of some trees, especially the autumnal images contrasting with the stunning monochrome infrared prints from Richard Hildred. It was a great evening, with excellent prints on display, and the website Competition page has been updated with the full results.

Good Morning All Last week we visited the nature reserves at Fir Hill quarry and Muckton wood. I have written a blog report on the evening which is on our website. You can always try something a little different like I did using camera movement. This week, Wednesday 24th June, a print competition will be held, with the categories of "Trees" and "Open" and is to be judged by Gail Wrigg.  The following week we have an outing to Kirkby Gravel pits. If you want advice on camera settings etc the outings are the perfect opportunity to ask other members while we all have our cameras. Regards Graham

Each year Louth Photographic Society begins a new project, one photo taken each month on a specific subject, that's 12 photos presented on "Project Night" in January. Last year the subject was "Prime Time" one photo each month taken with the same fixed focal length lens. This year the subject is water, the subject sounds easy enough, and I've completed 5 photos already, but I'm struggling a little with a photo for June. I'm currently on holiday in Corfu, an island surrounded by water which should be easy, but I'm yet to find the "definitive" photo for the project. These are my photos so far this month: Best regards Derek
