The longest lens that I owned up until a few weeks ago had a maximum focal length of full-frame of 300mm. Over the years I’ve owned several zoom lenses, and all of them reached that maximum focal length. They were mostly slow 70-300mm telephotos. For my Fuji system it was the 55200mm, which is approximately 82300mm when used on a full frame sensor.
When I bought my Fujifilm H2 recently from Fuji, they had an attractive cashback offer for their 100-400mm lenses. I’m tempted to sell my 55-200mm and purchase it. Do I regret buying it? Why I don’t have buyer’s regret
My 100-400mm Lens
The lens I selected was the Fujinon XF100-4000 f4 .5-6R LM OIS WR. It’s a lot to say, so I will now simply refer to it as the 100-400mm. There are also a lot of acronyms that I don’t know what they mean. OIS stands for Optical Image Stabilization and WR means Weather Resistant. Both are very useful features on a lens this size. It may appear to be a slow lens at first, but because it’s designed for Fuji APS-C sensor, it is equivalent to 150-600mm in a full-frame. At 600mm, an aperture of f/5.6 is very respectable.
