They are only JPG and a small size.
Bokeh seems nice.

I am not a good MTF reader
Can someone explain to me the IQ difference between the 16-35 f/2.8II and the 16-35 f/4 IS based on the MTF's?
I put them here (upper images are the 16-35 f/2.8II)
Simple, more contrast (bold lines) and more sharpness in the corners (thin lines), from left to right = center to extreme borders, the higher the lines on the graph, the more transmission of contrast (bold) and sharpness (thin), usually, black lines are for wide open aperture whilst blue lines are for f/8. At least, if Canon did not change its MTF legend
EDIT: after more observation of those MTF from 16-35/4L, damn, that will be bitingly sharp at f/8. Landscapers rejoice
I have the 35IS and it is a beauty. Highly recommend it.
Balance on the 6D is truly great. I used to own the 40mm and you are right it is faster though slower as some of my other lenses. And noisier too. But, I like the result of this lens. It is working well indoors in low light situations. The accurancy of AF out-of-the-box is pretty good. Of course, I just got the lens so I will have to do some more photography but I am sure I am going to enjoy it.I am going to check this lens out tomorrow. The thing I like about this lens from specs is that it is lighter and smaller as the Sigma 35 f/1.4, it has IS and f/2 (compared to the pancake 40mm)
It may be a better indoor/streetphotography lens on my 6D as the Sigma 35mm - which is bigger and heavier.
But I am still in doubt...
It is a great balance on a 6D. You will find the AF faster than the 40mm, but isn't anywhere near as compact. Still, if your two extremes are the 40mm and the S35, the 35IS is a nice balance between the two.
It is digital, colours are irrelevant.yes, the less time on pp the better
I should start a thread on how to purchase equipment and sneak it into the house without your wife knowingThat's what I'll be doing today - sneaking, not writing a thread, that is .
1) Always own up to buying one white lens. Once you've got one, they all look alike, so that gives you the freedom to own more.
2) When ordering from the Canon refurbished store, track the package progress and then change the delivery address to the nearest Kinkos/Fed Ex site. That way you can go and pick it up yourself without having to rush home to snag the attempted delivery notice tag off the door before someone finds it.
3) Separate checking accounts have prevented more divorces than any other innovation known to mankind.
4) You will never be able to sneak every purchase in, so build up some immunity. Do that by never, ever criticizing or questioning her when a box arrives from an online clothing, purse or shoe store. Smile. Complement her on her good taste and make a point of being pleased that she bought herself something nice. You are earning credits that you can cash in later.
5) Always include some low cost item in your purchases from B&H and Adorama – "Oh yeah, I ordered some batteries...a filter...a camera strap...etc. I don't know why they send that stuff in such a big box."
6) If you've got a big purchase planned, start the process early on. I'm going to start mentioning the new Tamron 150-600 zoom soon so that by the time Black Friday rolls around she'll be ready to tell me to just get it.
7) Never miss an occasion for a gift. A piece of jewelry tucked into an Easter Basket is also a great way to buy immunity for the future.
8 ) Ask for gift cards from your preferred photo store. "Oh that. I ordered that with the gift card you gave me last Christmas." (plus an extra $800, but who's counting)
9) Get yourself a "man cave" where you can stash all your toys. Preferably in a room she seldom goes into.
I have more, but these should be a good start.
Glossy/White-faced Ibis Hybrid
Common to Colorado are the White-faced Ibis. They are beautiful birds, long slender necks, burgundy feathers with green wings and a patchwork of faintly colored feathers on their backs. These birds are fairly elusive here in Colorado, and they have been a target of mine for a couple years now. I've seen flocks flying overhead, usually at sunset, and only been able to get remote silhouette shots.
A couple days ago, at the Cottonwood Creek wetland, a good-sized flock of Ibis were hanging out, bathing and preening in the calmer backwaters of the wetland ponds. After some time carefully getting into position, I finally managed to get some nice shots of these beautiful waders. Once they were finally framed in my lens, I realized that at least one, if not a few, looked like Glossy Ibis. A VERY similar bird, the Glossy Ibis is endemic to the Everglades of Florida, and very rarely ventures anywhere else. The key difference is the very thin white border around the Glossies face, where as the White-faced has a much larger border that blends into their burgundy and green head and neck feathers. However the face on the Ibis in front of me was a thin and mottled white line...somewhat different from a Glossy.
The White-faced and Glossy Ibis have only a very small region of the Gulf Coast where they cohabitate a couple times a year. In my research to identify the bird I've captured here, the only photos that looked identical were labeled "White-faced/Glossy Ibis Hybrid". I'm honestly unsure how common a hybrid cross between White-faced and Glossy Ibis is, however given the small overlap in their ranges, I suspect it can't be that much more common in Colorado than the Glossy itself.
