flawed logic.. you will always have more reach with a crop and a 1.4 TC.
And how many people are actually using a 1.4TC on an APS-C body? Its quite rare imho. I can also say add more n more extension rings if u just care about reach....flawed logic
Only advantage of APS-C is reach and price. But u dont have to save a lot more to get a better FF body than the endlevel APS-C. Yes, i hate APS-C or anything smaller than FF Still using it tough
I just think there are too many Canon DSLR models and levels. They should have entry, advanced and pro. Why there is like super entry (xxxxD), normal entry (xxxD), upper entry (xxD) advanced (7D) upper advance (6D) end Advanced (5D) and pro (1dX)? Its just too many imho. And all APS-C produce the same image quality. mostly the rebels even produce better images then the 7D cuz they get updated more often
I would NEVER get a 7D if it gives the same IQ as the cheapest DSLR from Canon. Paying so much money just for a better body material is ridicoulus imho. Or wow 10 FPS? Press and pray is not my style... If i wanna be somewhat professional id at least get a 5D.
First off, if you honestly think people who use cameras like the 7D, 5D or 1D lines simply "press and pray", your a fool. Not only are you a fool, your an insulting fool. You can't simply "press and pray" to produce high quality, artistic photography or photojournalism. Especially as AF system increases in complexity (the 7D AF system is quite a bit more complex than the that found in lesser models, and the 5D III/1D X AF system is even more advanced). You have to learn the AF system and understand how to use it effectively, in a variety of situations, in order to utilize it properly to help you produce quality photography. It is most assuredly NOT "press and pray". If that is how you approach photography when you find a higher-end body in your hands, you do not deserve to use a higher-end body. Foolish notion!
The simple fact of the matter, though, is the 7D gives BETTER IQ than the cheapest Canon APS-C. The notion that sensor is the sole factor in IQ is fundamentally flawed, and why so many on this forum do not understand the true value an APS-C camera like the 7D. There are numerous other features offered with the 7D, not the least of which are its superior AF system and higher frame rate over the xxxD and xxD lines, that lead to better results in more cases. An increase in the number of usable outcomes is a very valuable thing, and more often than not those features are in addition to the image sensor, not solely because of the image sensor.
Let's drop the notion that sensor is the end-all, be-all of image quality. It is not. I'd offer that frame rate and AF system are critical, if not the most critical, factors in IQ for a significant amount of photographic endeavors. Pretty much anything that involves automatically locking focus on non-stationary subjects, or requires actively tracking subjects in motion, can greatly benefit from the additional features the 7D offers over the xxD and xxxD lines. I'd also be willing to bet that the keeper rate for the 7D is far higher than that from either a 60D or 650D, or any other prior version of those lines, thanks to its superior features...despite the fact that the image sensor is the same."Press and Pray"...hah. You really don't understand how to use an AF system, bub.
Regarding the use of teleconverters on APS-C. I use them. Hell, I've used teleconverters with both the EF 300mm f/2.8 L II and the EF 500mm f/4 L II on my 7D. I use both the 1.4x and 2x, and if Canon made a 1.7x, I'd use that too. Primes frequently have far more to offer from an IQ standpoint than sensors do. A lot of people complain about how "soft" the 7D is...that is true, sometimes...when using older lenses. Slap on pretty much ANY Mark II lens on a 7D, and that "soft" disappears, replaced by some of the sharpest detail you've ever seen. The Canon 18.1mp APS-C sensor is a good sensor...however it is a very, very high density sensor. If you use inferior glass with it, all the flaws OF THE GLASS are revealed
. The only real drawback of the 7D is noise, and then, only at ISO settings above 2500 (and even then, with the increasing availability of advanced noise removal tools, such as Topaz DeNoise 5 (which has stellar random noise removal AND debanding!), high ISO noise is becoming less and less of a problem.)
If you have any experience with bird photography, or a lot of wildlife photography, you'll know that there is NEVER any end to the need for reach. You can always, always, always use more reach. The 5D III doesn't offer better IQ than the 7D in any reach-limited scenario. When you pair those cameras with say the EF 600mm f/4 L IS II and a 1.4x TC, the 7D will always extract more detail. If you are willing to move up to the 1D line (or, if the 5D III ever gets its f/8 patch), you could then slap on a 2x TC, and achieve 1200mm. However you'd still be short what the 7D w/ 600mm + 1.4x TC offers...a whopping 1344mm effective, and at a faster aperture to boot (f/5.6 vs. f/8). (Assuming reach was not your greatest need, the 1D X and 5D III certainly offer other non-sensor features that will help improve IQ...better AF systems, higher frame rate in the case of the 1D X, more features to help you nail the shot, etc.)
