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.

At our meeting last night an instructional DVD on “Macro Photography” was shown. The DVD material was quite detailed, very interesting, with lots of facts, and figures to consider. After the break, I attempted to unpack some of that detail with a practical demonstration using my own camera, (the OM Systems OM-1) a set of extension tubes, an LED light, and an on-camera flash. There’s lots to consider when beginning with macro photography, first of which I would say is get to know your camera, being able to adjust aperture, ISO, and watching the shutter speed if shooting in Aperture Priority mode to optimise exposure, and detail. Next, lens choice, select a lens with the closest focusing distance, if you have a dedicated macro lens then use that, otherwise a set of extension tubes may bring your camera closer to your subject. Choosing a subject, and lighting the subject with a LED light, or a camera flash speedlight will yield improved results. Don’t be afraid to experiment with settings, only by continual practice will the best images in this incredible genre, that is macro photography be realised, above all have fun. We meet at Red Hill Nature Reserve, Goulceby next week, Wednesday 4th June, to hopefully capture some amazing macro photography.

Good Morning all What a good night we had last Wednesday in the LPA Battle against Lincoln. We managed three twenties and overall won by twenty points, the second best score in the first round overall only bettered by Scunthorpe who we meet next. This week, Wednesday 28th May we are showing a DVD, "The Essential Guide to Close-up and Macro Photography". I was asked if I could get a speaker on the subject but there didn't seem to be any so a DVD should be a good substitute. We have a print competition coming up, with the categories of "Britain's Coastline" and "Open", it covers a very large area including all the islands. Due to outings and the LPA Battles it will not be easy getting our prints to Dave, so you can bring them this Wednesday or send an email with your entries to Dave as usual and bring them on the night if you don't see Dave beforehand. If you do this, you must send the titles to Dave to get on the scoresheet. I have confirmed our booking at the Splash on 4th July as I had twenty members and partners replying indicating they would be attending. I have paid the deposit so if you could give me £5 per person deposit when you next see me. They have also asked us to have menu choices decided two weeks before we go. Regards Graham

On Wednesday 28th May, the Society will be showing a DVD that hopefully will give advice on techniques, and skills for “Macro Photography”. The following Wednesday we will meet up at Red Hill to practice those skills, and techniques. So, what is “Macro Photography”? Wikipedia gives the following definition: "Macro photography is extreme close-up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater than life-size." To photograph small insects, or flowers larger than life-size a photographer will need to have a lens suitable for the purpose, a dedicated macro lens, a close focusing telephoto zoom lens, or the least expensive option is a set of extension tubes. With my Fuji camera system I used a 70-300mm zoom lens to capture these images, now that I am using the Olympus / OM System cameras I can buy a dedicated macro lens for about £400, however rather than spending a lot of money, I have opted to purchase a set of extension tubes, for £33, the tubes fit between the camera body and the lens enabling closer focusing to the subject. One of my techniques for close focusing is to obtain focus, either with auto focus, or manual focus, and gently rock back, and forward to fine tune the focus. A camera flash, or a portable LED light can also be used to highlight the subject.

Good Morning All Last week at the club we held our monthly PDI competition, with the categories of "Seasons" and "Open" judged by a new judge to the LPA, Dane Butler. There is a report on the evening on our blog and all the results are on our website under competitions. Well done to Steve Chapman who came first in both subjects. This week, Wednesday 21st May, we host Lincoln in the first round of the print LPA Battles judged by Brian Grommett. Don't forget, subs are now due, also keep going on your project, prime time if you are taking part. Regards Graham

The first round of the LPA Print Battles was held last night, Louth hosted Lincoln for this round. The judge for the evening was the excellent, quietly spoken, knowledgeable Brian Gromett. Brian reviewed the prints in his usual calm manner, holding back four prints from the Lincoln entries, and nine prints from Louth. The club room was packed for the evening, I was especially taken with three of the detailed insect prints submitted by Lincoln, and presumably by the same author, as the pastel like green backgrounds were in the same style. It was an excellent and close fought competition, well done to Lincoln, but after the points were added up Louth led by 20 points.

Our PDI (Projected Digital Image) competition with the categories of “Seasons”, and “Open” was held last night. Dane Butler was the judge for the evening, and there were some stunning images submitted into the competition to review. Dane judged the images fairly, majoring on the technical imperfections of the images, depth of focus, composition, elements within an image that could have been removed, improved cropping of an image, and image titling. Thank you to Dane who is a new judge on the LPA circuit, I felt he did well, he does need to think about addressing the audience with his critique of the submitted images, and speak a little louder. I know that the technical critique helps us to develop our skills as photographers, sometimes though, it would be nice if a judge could concentrate on the pleasing aesthetics of a submitted image, rather than on the technical deficiencies of an image, for me as a personal viewpoint it should be how an image has an impact on the viewer, or the story that the image conveys. I present two images for consideration, the first of the heritage passenger train hauled by the steam locomotive “Eric Treacy” drawing into Goathland station and being met by the Stationmaster on the platform conveys a story, the second is of a visually impactful corn flower, both images have technical imperfections but are nevertheless stunning. Congratulations to Steve Chapman, and Graham Harrison for achieving the highest placings in the competition. All the competition results, and top three placements from the competition categories have been uploaded to the Competition page on the website.

Our AGM was held last night; it was a productive evening with all the Society Officers re-elected for the forthcoming year. A big thank you to Peter Cory who has stood down from the Committee, Paul Twomey has been nominated in his place on the Committee. Following the AGM, the cups, and trophies were awarded to members with the highest points scores in the competitions.

We held a PDI Competition last night with the categories of “Local Events”, (the “Local” designation applies to any photograph taken within a 25-mile radius of St. James Church, Louth) and “Open”. Our own Graham Harrison was the judge for the evening, and he did a sterling job of selecting the top three highest placed images in each category. All the results of the competition can be viewed on our Competition webpage. I want to take a moment to praise the work of our Competition Secretaries, Dave Turner is the Print Secretary, he collects, collates the submitted competition prints, and produces the score sheets, he also submits club entries into the LPA Fosters competition, and the LPA Battles for members. Harry Kerman is our PDI Secretary, he receives submitted digital images usually via WeTransfer, collates the entries, produces the score sheets, and presents the images on the competition evening, as he did last night. Our Society would be much poorer without the hard work and dedication of these two individuals. It would be a real help to both Competition Secretaries if you could pay attention to the titles of your submitted entries, in the topic categories a judge must be guided by the title, as well as the image to evaluate whether the image meets the topic criteria. Our next PDI competition has the topic of “Seasons”, carefully choose both the image and the appropriate title to help the judge. It seems a shame to put a lot of hard work into taking a photograph, editing the image, and submitting the entry, only to lose points because your image did not meet the criteria. I would also encourage you to join our outings in June, it’s where we can socialise, and learn from other members how to use our cameras and gain some composition tips. This photo of an Orb Weaver spider taken at Chambers Farm Wood, from last year, is an example of what can be achieved on our outings.

Good Morning All Last week at the club Derek Smith kindly organised a studio night for us all, it was a very successful evening with Derek providing all the lighting, backdrops, and booking the model. Thank you, Derek, for all your hard work organising the evening. This week, Wednesday 30th April, we are holding a local PDI competition, with the categories of "Local Events" and "Open", you have until midnight tonight to get your entries to Harry. The local is always judged by members and this week you have yours truly judging. The following week it is that time of year already when we hold our AGM and presentation night. If any members have trophies to hand in, this week please. The week after the AGM it is the first monthly PDI competition of our new competition year, Seasons and Open, you can begin sorting out your entries for that one as well now and send them to Harry after this Monday to avoid confusion. Regards Graham
