Last week, I listed my photography equipment. This week I thought I could write about the process of decision making I used to decide to buy one of the lenses.
The first time I had the privilege of holding and looking through a Canon 300mm f/2.8 I was hooked. It’s a double collegiate swimming. I watched the competition’s 10-meter diving when a press photographer sat down beside me and started taking pictures of the competition. One comment led to another and the next thing I knew I wanted the camera and lens and take photographs that divers. I do not know if any of the pictures I took were already printed in the newspaper, but from that moment I wanted a 300mm f/2.8.
Unfortunately, when I was a child in college and three in high school. There was no way I could afford such an expensive lens, so I opted for a 300mm f/4L Canon FD. I praise the f/2.8 model a couple of times, but the f/4L is a great goal and I was very happy with it.
This is the current model F/2.8L Canon 300mm IS USM. A superb piece of equipment.
Recently, I decided it was time to buy a new 300mm lens and my first thought was to buy the Canon EF 300mm f/2.8L IS USM. Emotion and pleasure potential of opening the box of f/2.8 L side, common sense tells me that I must also take into account the f/4L. As you know, common sense often gets in the way of fun, but now I had a difficult decision. I do not expect everyone to agree with my decision, nor that all should come to the same conclusion if they considered the same factors. However, it is the process I went through to decide which lens to buy. Your process may be different.
Why do I need a 300mm lens?
My first love of photography is nature photography and if you want to take pictures of birds and wildlife without scaring them away, a goal long term is essential. This was the easiest part of the process. I needed a 300mm lens – at least that’s what I said to my wife.
Price
By comparing the price of both lenses is easy. The f / 2.8 L, depending on where you look, around $ 4400 plus taxes and / or shipping. The f/4L USM is $ 1270. Since I do not work for a newspaper or magazine and not an employer to purchase the target for me, price is an important consideration. Through a series of circumstances (some call it luck) I had saved enough to buy the f2.8. However, I could choose to spend all my savings on photography f2.8 affected or purchase the f/4L and have money left over for other “toys.” The f/4L won on price.
Physical Size
If you will be involved in nature photography, you’ll eventually get out of town and the car. Remove lens and all your other gear through rugged terrain is not the same as laying around the margin of a football field. Mountains, lakes, marshes, woods are commonplace. The f/4L weighs 2.0 pounds and is 8.7 “long and 3.5 cm in diameter. The f/2.8 weighs 5.7 pounds and is 9.8″ long and 5 cm in diameter. The difference is 3.7 pounds significant when added to all other devices – a tripod, a camera, other objectives, etc. f/4L won it goes.
Max Aperture
The f/2.8 is much faster than f/4L but only by a stop. Can we stop to overcome the advantage of price and size of f / 4L?
I’m not a sports photographer so it is unlikely that I’ll never be fast action shooting at low light inside stadiums or fields, illuminated at night. However, the best moments of shooting for wildlife are early morning and late at night to shoot in low light is a strong possibility.
When I fell in love with the f/2.8, digital SLRs are not widely available (the EOS cameras had not been introduced) and photograph of the film was still king. My film of choice then was Kodachrome 64. There were things you could use to “push” the film, but for the most part, ASA 64 was the fastest, you can use and maintain excellent image quality. At this speed, a goal which was a stop faster was a big deal. Today, the lowest ISO on my Canon 7D is 100. I can easily increase the ISO two stops to 400 with little or no deterioration in IQ. Therefore, I can get shutter speeds with today f/4L I could with the help of Kodachrome 64 mm f / 2,8 which makes it even more difficult to justify the difference of over $ 3,000.
There is also the issue of my camera being with a cropped sensor compared to full-frame sensor from my old Canon F-1 but it’s the same with both lenses.
Ultimately, I bought the Canon EF 300mm f/4L IS USM. You can have different considerations and you can buy, or if you want to buy the f/2.8, but I’m very happy with the f/4L. Besides, I can always rent an f/2.8 so I really need to use one. I will look into the lens in a few weeks when I used it enough to really make if it is not.
Since I do not have a lens f2.8L for visual comparison, for this photo, I placed my 70-200mm f/2.8 L lens next to the 300 f/4L USM. As you can see, they are similar in size and 300 mm is actually 1.2 pounds lighter.
In photography, silver, or lack thereof, is often our primary consideration, but even if we can afford what we think about the purchase, using a disciplined approach, decision-making process before buying is always helpful.
Wish List
As promised, here is my wish list, in no particular order. Keep in mind that it is dynamic and may still have elements added.
- Second camera body – I want a 5D Mark II, but I may decide to get the T2i or 60D instead. Both have advantages – 5DMark II has a sensor size and a great camera. The T2i and 60D have the same sensor as my 7D. I could also buy two of the 60D and have money left over for the money it would take to buy the 5D Mark II.
-Filters – I’ve never been a big user of filters, because I do not pay top dollar for the glasses, then put another piece of glass on them. However, there are three that seem essential – a circular polarizing filter and two neutral density filters – an optical density 0.9 or 3-stop filter and an optical density of 1.8 or 6-stop filter .
- Canon EF 35mm f/1.4L USM Wide Angle Lens – Yes, I have a 24-105 zoom, but I like to have a primary objective which is equivalent to a 50mm lens with a full frame sensor.
- II Speedlite Flash Canon 580EX
I’m sure this list will grow, but these are items that I think most often.
Keep in mind that equipment does not take pictures. Anyone can take photos badly with the best equipment available. Only good photographers can take good pictures or large.
