p.1 #1 · Birders: 7D vs. 70D


How does the focus on the 70D stack up, compared to the 7D?

And how good is the 7D on birds?

I suspect I'm going to be doing a couple of gigs worth of in-flight shots in a couple of months, and this would be useful to know.

And any specific settings that would up the correct-focus ratio?

the AF on the 7D is more advanced in terms on in flight shots with point expansions and what not many will draw on this. For the 70D I have enjoyed it thoroughly for bird photography. High ISO (1600-3200) has been fine for my likings (I could not stand the 7D at ISO 800). For in flight photography, I did really well with the 7D . . . but I also did quite well with the 5D Mark II which has a poor AF system in comparison. The 70D Will give you better AF in live view, but about the same AF when focusing through the viewfinder IMO. Many will contradict this, but these are also people who have not spent time with a 70D.

If AF is a main concern, you may also consider the 1D Mark III used for about the same price. It's a work horse camera, and I use mine a bit as of lately, even with the 70D.

Background for that - I did shoot a 7D for almost 2 years before moving to a 5D mark II, then used the 7D as a backup. I replaced it with a 1D Mark III, and still use it. I picked up a 70D for fun, and have also used it for bird photography with great results, even in harsh conditions.

I had both and I sold the 7D. AF consistency is much better on the 70 (with my 500/4 + 1.4x) for stationarry targets and I find it tracks better for BIF.

The downsides are stupid sd card and smaller buffer but for me, not a machinegun shooter, it is a non issue.

Here is an iso 3200 shot of a chipping sparrow

I had a 7D and sold it and bought the 70D and love it. With the 7D I could never get AF consistency with either a 400/5.6 or 100-400. ISO 800 was also bad for me on the 7D. I have no such issues so far with the 70D. I like the lighter weight and the live view touch screen focusing is incredible. The BIF AF has worked good for me with the 70D.
