YouTube Recommendation: Christopher Frost

Christopher Frost Photography

When I started looking for additional lenses for my 760D, the YouTube channel by Christopher Frost was among the first I subscribed to. Chris is an enthused photographer living in Cardiff and currently training to be become a vicar. He characterizes himself as a “lens enthusiast” and continuously publishes detailed reviews.

I’ve come to appreciate these reviews a lot. Chris follows a thorough and consistent scheme, so that his reviews can be easily compared to each other. From time to time, he takes advantage of that himself and combines several reviews into a “battle” – for instance, ten different 50mm prime lenses, or eight ultra wide-angle ones. Hence, it not only becomes evident how one particular lens behaves under various settings or on different cameras, but you can also easily compare lenses to each other.

He assesses the following points:

  • Look & feel, build quality, and equipment
  • Image quality (sharpness, contrast, chromatic aberrations) – on a full-frame as well as an APS-C camera, as far as applicable, at different apertures, and (for zoom lenses) at different focal lengths.
  • Distortion and vignetting
  • Close-up image quality
  • Behavior against bright lights
  • Bokeh

When it comes to lenses, he tests about everything that can be mounted to a Canon DSLR; in particular off-brand ones. Thus, he created more than a 130 videos by now. Recently, he obtained a mirrorless camera, so that lenses made specifically for DSLMs are now being reviewed as well.

The videos are made in a very likeable way. In addition to the always-similar test images, they always contain some example images as well as personal experiences when using the lens. He’s enthusiastic about what he’s doing, but he doesn’t overdo it. The videos have a very convenient duration of five to ten minutes each. His British English can be easily understood. Based on his reviews, for instance, I have decided to go with the Tamrom SP 70-300mm ƒ4-5,6 Di VC as my telephoto zoom lens.

PLAYLIST RECOMMENDATIONS

In addition, Chris has some other playlists mostly focused on music, TV shows, and his engagement at Church.


CONCLUSION

Recommendation: If you’re looking for well-made, substantiated, and informative reviews on lenses for Canon cameras, then Chris’ YouTube channel comes highly recommended!

What I’ve learned: Due to the comparability of the reviews, I have learned how significantly different lenses can behave concerning sharpness and color-fringing at different aperture settings and focal lengths, and also how big the differences can be when using one and the same lens on full-frame body or an APS-C camera.

Rented and tested: Sigma A 50-100mm f/1.8

Sigma A 50-100mm ƒ/1.8 on the Canon 760D

One remaining gap in my equipment list is a high-quality tele-zoom lens – in particular one that can capture portraits with a nice blurry background (bokeh). I already have two prime lenses that can be used in this way: the “nifty fifty” Canon 50mm ƒ/1.8 and the Tamron SP 90mm ƒ/2.8 Di VC Macro. But for situations like events, where people are moving around, I prefer the flexibility of a zoom lens.

Two types of lenses come into mind: first, the “classic” 70-200mm ƒ/2.8, which is available from Canon, Sigma and Tamron in various different styles. Second, the rather new Sigma 50-100mm ƒ/1.8, which is designed specifically for APS-C Cameras like my Rebel T6s. All these lenses have one thing in common: they are in a price range where you no longer buy one “on a hunch”. Of course there are numerous test reports and reviews online. But there is only one way to find out which glass fits my personal photography  style: try it out.

SO TEST THEREFORE, WHO JOIN FOREVER

Only a few of you will be so lucky to have a photographer friend who will happily lend such a lens for some time. Fortunately, there are now quite a number of suppliers who offer to rent photo equipment – not only lenses, but also cameras or entire flash and lighting equipment. I have used such a service twice now, and have had very good experiences doing so.

ZOOMYRENTALS

The company I use is ZoomyRentals.de. They are in Berlin, Germany, and offer a wide variety of camera, lenses and accessories by and for Canon, Sony, and Nikon. They ship only inside Germany of course, but wherever you are – search for “rent camera lens” online, and I am sure you will find a provider in your area. The steps described below will most likely be the same. Here is how it works:

  • You register
  • When ordering for the very first time, you have to upload a copy of your ID to your user profile for verification. Your name and address have to be clearly visible.
  • You select the desired equipment
  • You choose the starting date and the term of lease – this can be from 3 days to 4 weeks.
  • There you go!

I highly recommend signing up for the option insurance that is offered with each order. With expensive equipment, it is better to go safe than sorry.

SHIPPING

A DHL messenger does the delivery. You will receive your equipment on the morning of the first day of the lease, and a messenger will pick it up again on the morning of the last day. This is very reliable; delivery and pickup will be acknowledged with a signature, so you are on the safe side. Most of all, the package won’t accidentally end up on your porch or at a neighbor who might not be there when you need it.

All lenses come with front and back caps, lens hood, protection filter, and a pouch. This all will be safely packed between thick layers of foamed material. The box also contains the delivery slip as well as the return-shipping label.

Now you’re ready to go: you can use the rented equipment whichever way you want as long as you have it. Careful handling of all items is a matter of course.

SIGMA A 50-100mm ƒ/1.8

In December 2016, I rented the “big brother” of my Sigma A 18-35mm ƒ/1.8 for one week. I had friends visiting me during that time, and I also attended a festivity, so there were many opportunities to test the lens.

LOOK & FEEL

The lens immediately draws attention: It is big. And it is heavy. Holding the camera leisurely with one hand quickly becomes an athletic challenge; certainly not a lens to carry with you at all times, but only for specific occasions. If you set this in relation to its price tag of around (Dec. 2016) 1,000 €, you’ll quickly realize that this investment had to be thought through thoroughly. There’s a reason for the weight, though: A focal length of 100mm and an aperture of 1.8, as well as the zoom, require a lot of glass. In addition, the lens is made from sturdy metal and manufactured to high standards.

I liked the handling of the zoom as well as the focus ring very much. All in all, the finish, which is similar to my 18-35mm, is very convincing. Also, I didn’t mind the tripod collar, which is criticized in many online reviews, when handling the lens.

CONFIGURATION & OPERATION DOMAIN

This lens serves but one purpose: the creation of professional-looking portraits with beautiful soft backgrounds with an APS-C camera. The constant aperture of ƒ/1.8 is its unique feature. The zoom range is rather limited – just 2x, compared to almost 3x on the classic 70-200. However, especially when taking pictures at an indoor event, I quite liked the zoom range. The extra 20mm at the shorter end definitely are an advantage in this case, and at the long end, you can make up for a lot of the missing focal length by cropping the image. Thanks to the fantastic sharpness this lens renders, this is no problem at all.

One point you will definitely notice is that this lens lacks image stabilization. In a room with lights dimmed for a festive mood, even using an aperture of ƒ/1.8 and ISO 800, I ended up with shutter speeds between 1/60 and 1/10 of a second. Even when seeking support on a table or armrest, this makes it difficult to avoid camera shake – especially at 100mm. I could have increased the ISO, but with my Rebel T6s I don’t like to go above 800 when I don’t absolutely have to. The resulting image noise at higher ISO settings becomes too intrusive in my mind.

Consequently, I will definitely also try one of the 70-200mm ƒ/2.8 lenses with image stabilization. Even though the shutter speed will become even slower due to the aperture being one and a third stops smaller, the risk for camera shake blurring the image will still become significantly smaller. I will see how this actually turns out in practice.

RELIABILITY & IMAGE QUALITY

The Sigma Art zoom lenses with an aperture of ƒ/1.8 – the 18-35mm as well as the 50-100mm – are famous for their rather ambiguous relationship to autofocus. It seems to depend on the individual lens whether the autofocus works reliably in phase detection mode (through the optical viewfinder) or not. The copy of the 50-100mm I had was exemplary: on every picture I took, the focus was on the spot. With my 18-35mm on the other hand, this is a matter of luck. On about one third of the images, the focus misses completely. Online test reports confirm the impression that this behavior depends on the particular lens; the conclusions for both lenses in this respect range from “hopeless” to “no problems at all”.

The back-up solution is to use the camera’s live view, because the contrast detection autofocus will always work – though slower (if you want to know why this is the case, watch this lecture). If you’re patient enough, you can also focus manually. When taking shots on a tripod, I prefer this option anyway.

The image quality is simply brilliant. Even when shooting wide open, the images are amazingly sharp throughout the frame, with just a touch of softness in the corners. And they have to be, because apertures below 2.8 are this lenses specialty. The blurred backgrounds are nice and soft; only occasionally the bokeh becomes busy when there are lots of little lights in the background. When you stop down, the lens produces beautiful stars around light sources. The images I made, indoors and outdoors, people and cityscapes, consistently enthused me. The image quality is definitely a very strong argument in favor of the Sigma A 50-100mm ƒ/1.8.

CONCLUSION

Recommendation: The Sigma A 50-100mm ƒ/1.8 occupies are small niche: making professional portraits with an APS-C camera. It occupies this niche very well, though. The outstanding image quality was what excited me the most. The look and feel match the high value. Working with it was definitely very enjoyable!

Given the appropriate occasion, I will definitely try one of the 70-200mm ƒ/2.8 lenses with image stabilization for comparison. Based on the experiences gained with both lenses, I will then make my decision. You will read about that here as well.

What I’ve learned: Renting a lens for a week is the perfect way to test it thoroughly and gain an impression whether it fits your imagination and expectations. I will certainly use this option in the future again.

And: it is a lot of fun working with a professional lens like this! The week of testing however also proved the lens’ limitations. As beautiful as the images are, the 50-100’s wide aperture isn’t everything. Before taking a decision, I definitely want to compare, hence renting the lens for a week was the absolute right thing to do.

My Gear: The “Always-on” – Sigma C 17-70mm f/2.8-4

Sigma C 17-70mm ƒ/2.8-4.0

After I had chosen my new camera, the next question obviously was which lenses to get for it. This time, I had deliberately bought the camera body without the kit lens that usually comes with it, the Canon EF-S 18-55mm ƒ/3.5-5.6. I wanted something with a bit more “punch”.

KIT LENS ALTERNATIVES

Canon themselves offer the Canon EF-S 17-55mm ƒ/2.8 as an upgrade to the kit lens. It lets in two thirds more light at the short end, and even four times as much light at the long end! The downside is, it costs around 750,- € (Nov. 2016). Fortunately, there are “off-brand” lenses available as well. This resulted in the following short-list:

  1. Sigma 17-50 mm ƒ/2.8
  2. Tamron 17-50mm ƒ/2.8
  3. Sigma 17-70 mm ƒ/2.8-4.0

The main similarities and differences can be quickly summarized:

  • No. 1 and 2 both have a 3x zoom, and a constant maximum aperture of ƒ/2.8. Both have a price tag of around 300,- € (Nov. 2016)
  • No. 3 has a 4x zoom, but a variable aperture with “only” ƒ/4.0 at the long end. It costs around 400,- € (Nov. 2016)

After studying numerous reviews, I dropped the Tamron from the list. The reviews consistently stressed that the Sigma lenses to have better image and build quality. So the remaining question was: what do I consider to be more important – longer focal distance or wider aperture? 17-70mm or constant ƒ/2.8?

In the end, I decided for the 17-70. I preferred the greater flexibility given by the extra 20mm.

The Sigma plays a major role in the fact that photography has become so much fun for me with the new camera. Not only because it lets in much more light, making it easier to take good pictures indoors or at night – image sharpness and colour rendering have enthused me as well. As a result, it has truly become the “always-on”. Its external values are also convincing. I consider the used materials and the build quality to be very good. It comes complete with lens cap and lens hood – something Canon likes to charge extra for. Though it adds to the kit lens in terms of size and weight, it handles very well together with the camera.

Regarding taking pictures: The autofocus works very reliable on my 760D, as does the image stabiliser. This makes for good hand-held images even in difficult lighting conditions. It is not a true macro lens  – but an image scale of 1:2.8 still allows for some impressive close-ups. And thanks to the wide aperture, pictures with nice out-of-focus backgrounds (bokeh) are feasible as well.

ARE THERE ANY DOWNSIDES?

Yes, based on my experience from the past year, there are a few points to consider. What I notice the most: the zoom is very easy-going. When carrying the camera with the lens pointing down, on a belt clip or shoulder strap, the lens extends to 70mm by itself, due to its own weight (including the lens hood). This can be a bit awkward, because it becomes more likely to hit something. Plus you’ll have to adjust the zoom most of the times when picking up the camera again.

When recording video, as long as you do not use an external microphone well away from the camera, quiet clicking and chattering from the image stabilisation and autofocus will be audible. I rarely record videos, so that doesn’t bother me too much.

The images themselves offer hardly any reason for critique. The light vignetting (darkening of corners) when shooting wide open can easily be fixed in post-processing with just a few mouse clicks. In Adobe Lightroom, for instance, simply choosing the correct lens profile already does the trick. Chromatic aberrations – green and purple fringing on contrasting edges – are negligible.


CONCLUSION

Recommendation: If you are looking at an upgrade from the kit lens, I can highly recommend the Sigma C 17-70mm ƒ/2.8-4.0! It is very versatile, reliable, and renders compelling results. Even more so when taking into account that the “original” from Canon costs twice as much – but in my mind, it’s not worth the extra money.

The sister lens, Sigma 17-50mm ƒ/2.8, is worth having a look at as well – especially when you’re taking videos on a regular basis, where a constant aperture is more important. Two of my friends have it, on a Canon 350D and a Nikon D7100 respectively, and they are happy with that choice as well.

What I’ve learned: The thorough research before getting the new lens was absolutely worthwhile. In particular: when you are looking for a new lens, have a look at the third-party manufacturers as well: Samyang, Sigma, Tamrom, Tokina etc. In terms of quality as well as value for money they offer some very interesting alternatives.
