I still feel a good copy of the 100-400 trumps any other options for a long lens Even with a 1.4xtc on the end of it. A great way to get a equivalence of 800 or 1120mm on a given day. Not to mention the svelte size and overall weight. The 300 f4 is a fine lens don't get me wrong, but in most all my cases I can't be strapped with a single focal range choice. The sharpness of my copy of the 100-400 is simply sublime. I think perhaps I lucked out I don't know.


I have three 100-400 lenses. They are all sharp.

Considering a move to micro 4/3 from a D500 + Sigma 100-400mm for bird photography. It would be an OM-1 coupled with either a 100-400mm or 300mm + 1.4TC. For those that have these combinations how do you rate them in terms of IQ, focus speed and acquisition? I like the zoom facility but wonder how well it performs for BIF.

I have both lenses and find the 300mm lens, even with the 1.4x TC, to be slightly sharper and quicker to focus than the 100-400mm lens, but only when making a conscious effort to discern the difference. What the 100-400mm lens has in its favor is the versatility in focal lengths.

Each lens has its own strengths, but the overall IQ and focus speed are so similar that one has to weigh a fixed focal length of 600mm against one that has a 600mm range of 200-800 (in 35mm equivalency). Acquisition of BIF, for me, is much better with the 100-400mm lens, especially with fast, multi-directional flying birds like swallows. With herons, egrets, birds of prey, and even with most ducks and geese, acquisition isn't so bad with the 300mm lens, although I sometimes find those birds filling the frame quickly with no option to zoom out.

In planning for an outing with emphasis on large birds and relatively stationary wildlife, I'd take the 300mm lens. For small birds in flight or for an outing that involved more eclectic subject matter, I'd opt for the 100-400mm lens. Of course, another important factor is the amount of light available, and the obvious difference in the lenses that one should consider is that the 300mm lens is a full stop to a stop and a third faster/brighter than the 100-400mm lens, although that evens out a bit when you slap a 1.4x TC on the 300mm lens..

I moved from a d-500/500pf and 300pf to an OM-1/100-400 and 300f4

The D-500 is fast, maybe the fastest, best focusing DSLR ever but the OM-1 is faster and more accurate. The reason has to do with the 1000+ quad pixel focus points and the BSI stacked sensor. The D-500 in GRP AF mode will grab a BIF almost instantly and focus on the closest part of the bird but the OM-1 in subject identification: birds will focus on the eye if the eye is visible. To accomplish the same image with the D-500 you need to get a SP in AF mode on the bird's eye.

My D-500/500pf and 300pf took amazing pictures as Nikon primes are fantastic. Your Sigma 100-400 is not nearly as good. However, to get a great shot with a prime the particular prime needs to the correct prime. I found the 100-400 zoom considerably more flexible. A typical situation is where you find a perched bird, take a portrait shot that you want to fill the frame, then wait for a BIF shot where you want to make room in the frame for the bird with spread wings. You will find that the 100-400's extended reach (800mm vs 600mm) quite valuable.

I normally shoot 20 f/s electronic shutter which is superior to the 10 f/s mechanical shutter with the D-500
