So, the 500 f/4 II has been returned. I was sad to see it go. That is a heckuva lens.
A few pics:
5DIV, 500 mm, 1/1250, f/4.5, ISO 250
700 mm, 1/2000, f/5.6, ISO 200

700 mm, 1/3200, f/7.1, ISO 12,800 (I was testing things and liked the pose)

700 mm, 1/1250, f/5.6, ISO 1600
700 mm, 1/2000, f/5.6, ISO 1250
So, my home set up needs some work, but those were taken out my office window at my bird feeder about 35 ft away (exif is 10.4 m, seems a bit long). If correct, playing with the math, the 700 mm (500 f/4 IS + 1.4 TC)
is 311 ppi. So, that is about the limit if I keep my home set up as is. But being able to take a break from work (I am home office when not traveling), open my window and shoot some pictures is a very nice afternoon break. Thus, the potential for 700 mm is opening up opportunities.
Some other general observations:
AF Speed:
- 500 f/4. Just really fast.
AF Accuracy:
- Very impressed. Very few shots needed to be deleted for an AF miss. I took the time with the 500 f/4 II to mount it to a tripod and use the LensAlign to dial in the AFMA bare and with TCs. I think this made a huge difference compared to what I experienced with the 400 DO II. Granted, once I finally dialed in the 400 DO II, it was pretty remarkable as well.
IQ:
- Excellent. As good as I've seen. While the bird shots at my home set up benefited by the extra reach, there is no doubt I am seeing an extra level of sharpness compared to the Sigma (which I still regard as a sharp lens...this is just better). I am seeing detail to the ridges around the birds eyes instead of just the ridges themselves.
Portability: True Transport
- Size: 500 f/4 II: 15.3x6.7 inches. Sigma 150-600S: 11.8x4.8 inches. I can close the zipper on my GuraGear 22L Kiboko, but I would be buying a new pack. It barely fits. This is the first lens that makes my 150-600S look small(ish).
- Weight: 500 f/4 II: 7.5 lbs. 150-600S: 7 lbs. Not much of a difference in the bag. The balance of the 500 f/4 II is something in the field.


Usability:
- For walking around, the 500 f/4 II was great. Incredibly well balanced, which makes it feel so light. I had my blackrapid strap anchored to the foot. I walked, drove, and shot snowy owls for 4 hours. When first testing the lens, had a few issues hand holding, but a few small adjustments to my technique and it is actually very hand holdable. I could stay on target with minimal movement for longer than it takes to fill up the 5DIV buffer, let it clear, and then fill it again.
With TCs:
- Very similar to the DO II. It may even take the TCs better. But 1.4TC is fast AF with great IQ. Very slight dip in contrast and AF speed with the 2xTC, but still very usable, probably still better at 1000 mm than the 150-600S at 600 mm.
Fun Factor:
- Ok...this opened up a type of photography I have wanted to do, but have been unable. I positioned my bird feeder to be able to shoot from the house. My 150-600S was ok, but if I ever posted an imaged, it was only 1-2. The quality just wasn't there. Playing with the calculator, part of that was just pixels on target. But with the 500 f/4 II + 1.4TC and the 5DIV, this is something I can do now. But it is 311 ppi, less reach, fewer MP is just not an option. So new ability = fun.
- Compared to the DO, they are fun in different ways. I am looking for the right analogy, but the DO II is like a great high end sports car. It is light, sporty, quick, and easy to handle. It just makes you smile. The 500 f/4 II is more like a luxury sedan. Elegant, efficient, powerful, and ultimate, superb handling. The 400 DO II, you hop in and out of a car, you react quickly to birds movements, and barely notice the lens. The 500 f/4 II, you can do all those things, but it is slower. You have to think about the lens. But it works great.
So, this has been a lot of fun. Next up is time to get a bit serious. The T-stop issue with the 150-600S has me questioning it's place in my kit. I had intended to keep it, as I have really enjoyed that lens and it has accounted for several of my favorite images each year I've owned it. Yet, since I bought it, the 100-400L II was released. I already own the 70-300L, which is a great little lens, and I do wonder if the 100-400 II and the 70-300L being in the same kit. I like each lens have its own distinct purpose. And, I am looking at these Big White Lenses.
So, my quick plan and likely my next post, is to look at all the scenarios which I would use these lenses, and decide which lens would be best for that scenario. The trip to Florida is now an annual event as is chasing Snowys and eagles. I can rent lenses for trips, but I will continually make trips to photograph wildlife (Yellowstone in early Sept this year). I shoot loons and turtles from a kayak, and I would love to be able to take morning/afternoon breaks, open my office window and rattle off some shots of birds at my feeder.
So, I probably could justify about 5 different lenses.... hmmmm.... ok...have a good weekend everyone.
