The first thing to clarify is that, while Netra and I love to photograph birds, this blog post can relate to all wildlife photography. Wild animals have the tendency to stay as far from us as possible and we need similar lenses and camera bodies as we would need for bird photography in the majority of cases.
We often get asked what lenses we use for wildlife photography. The answer is simple. The best and longest we can possibly afford. And you, too, should consider buying the very best and longest lens you can afford on your budget. I always suggest – and mentioned to Netra – that if I had the choice of a top of the line camera with a medium quality lens I would rather the best quality lens with a lesser quality camera. Cameras change often enough to buy the best one later, whereas lenses will last you far longer and most professional or serious amateur bird photographers will go through many camera bodies before upgrading lenses.
Don’t be discouraged if you shoot with shorter lenses than what you see other people photographing with. Just practice on less wild birds until you can afford something longer. While we would recommend lenses with at least 400mm focal length (on a full frame camera body) for bird photography, you can get away with shorter ones at your local duck pond where birds are friendly and will approach. And, 400mm is not that long still when you consider how many advanced photographers choose lenses of at least 500mm or more to photograph birds.
Let’s take a look at different lenses for your benefit. Lenses are classed into different categories, like ultra wide, wide, standard, telephoto, medium telephoto and super telephoto. Lenses of 400mm or more are classed as super telephoto lenses, irrespective of how you achieve the focal length (that is lens alone or a shorter lens with a teleconverter).

Medium telephoto zooms like 70-200mm lenses or similar are great for larger animals up close, or when photographing seabirds like albatross from a boat during a pelagic outing. They can be used from photography hides (or blinds, however you like to call them) or cars, which can be used as a form of a mobile hide.

300mm lenses are also great for general wildlife photography, especially with crop sensor cameras and having a fixed lens doesn’t make things easy when animals let you approach closer than you anticipated, but the one thing we always do is take tight shots. Even head and shoulders portraits if needed.

400mm lenses are getting you into real super telephoto category now. On a typical APS-C sensor camera like a Canon R7 (1.6x crop) this lens is giving you a field of view the same as a 640mm lens on a full frame camera. Simply multiply the focal length by the lens crop factor to get the field of view equivalent in full frame terms. Therefore, 400mm x 1.6 = 640mm, it’s this simple.
Now you can see why wildlife photographers just LOVE the OM System with the 2x crop factor bodies, where our 300mm f/4 lenses are giving us the same field of view as a 600mm f/4 lens on a full frame camera body.

Beside focal length, there is speed of a lens. Speed refers to how much light can enter through the aperture at its largest opening (smallest f/stop). A fast super telephoto would be a 400mm f/2.8 lens, but that f/2.8 aperture comes with an eye watering price. The f/2.8 aperture would allow such lens to acquire focus quicker than an f/4 lens, but besides the cost of such lens, the weight also needs to be considered.
A 500mm f/4 lens would weight something similar and would be a stop slower than the 400mm f/2.8 lens, but with an extra 100mm of focal length. If you were to add a 1.4x teleconverter to a 400mm f/2.8 lens, it would become a 560mm f/4 lens (400mm x 1.4 = 560mm). Adding a 1.4x teleconverter to a 500mm f/4 lens would make it a 700mm f/5.6 lens.

Basically, adding a 1.4x teleconverter to a lens will cost you one stop of light. Adding a 2x teleconverter will cost you 2 stops of light. These losses in light mean your autofocus will be somewhat slower, even with top of the line camera bodies.
What, I hope, you are getting out of this is that there are lenses, then there are lenses and weights, costs and speeds that all contribute to the final product of your efforts. It all comes down to what you can afford, what you can hold and shoot with or you need to be prepared to make compromises.

There are many choices available to you if you want to photograph wildlife, I’ll list some below and you too can find your lens that you want to consider buying, or dream about until you can afford. For me, I prefer prime lenses (fixed focal length), although these days the zoom lenses are usually very good quality when you’re paying thousands or tens of thousands of dollars for them. I’ll list lenses from OM System from most expensive at top, to more affordable ones at the bottom.
OM SYSTEM LENSES
ED 150-400mm f/4.5 TC1.25x PRO
ED 300mm f/4.0 IS PRO
ED 150-600mm f/5.0-6.3 IS
ED 100-400mm f/5.0-6.3 IS
ED 40-150mm f/2.8 PRO
ED 40-150mm f/4 PRO
The interesting thing to note is that the 150-600mm zoom is one that was rebadged from Sigma (I think) and the Sigma (or Tamron with the same focal length) make amazing lenses for a Canon or Nikon body if you’re on a budget!

In closing: what lenses we would we recommend for wildlife photography?
As mentioned earlier, the best and longest lens you can afford. If you like a zoom, buy a zoom, if you like a prime lens, buy a prime lens and add teleconverters to increase your focal length. It’s really as simple as you working out what your needs are and what your budget is. I’ll attach a table below showing different lenses, crop factors and what they mean in a field of view equivalent of said lenses depending on what camera bodies you use. Don’t hesitate to get in touch with Netra or I if you need any help with any aspect of wildlife photography.
Stay safe!
Where are you?? Which state, city, etc??
