Pros: Weight & dimensions, fast AF, stabilization, no AC, backlight resistance, extended series III extender, sharpness already in TA
Cons: High, slightly unbalanced low price with a Canon 1 Series body
Opinion: I suggest that before I write my impressions, I deliberately took time to test and try to get to know this magnificent optic better. Canon did a work, removing alibi and apologies to those who criticized the previous model for low backlighting, AC , Microcontroller, etc. I'm just starting to talk about clarity: the 400 DO Series II has reached levels close to Canon's other Series II supertels, delivering great images that are already fully open. For me it was a great surprise, especially if used with series III multipliers. The Digital Picture.com test (which, at the moment, I think is the most reliable for testing and method), shows a slight (slightly) lower clarity To 300 F2.8 II and 500 f4 II, to the most open diaphragms; Starting to close this difference, it shrinks, but it is still less clear than the other II series. However, we are only thinking on the basis of a visual evaluation of 100% crops, taken from studio shots and in optimum light conditions. Needless to say, such cThey will never be seen in nature. Therefore, these minimum differences will be more influenced by the photographer's ability and experience and the reflex used (if FF or APSC), which compared the quality of optical optics. Rn Despite the work done by Canon, 400 DO II pays, At least for now, the clutch of a series of prejudices (overwhelmed by the internet), linked to small flaws that characterized the first version. Nothing serious and / or unsurpassed, if you have the experience, the passion and the desire to take. RnNot to say that those that were defined as the "weaknesses" of the previous model were completely solved in this second version. Rn The chromatic aberration is non-existent. You notice a slight vignetting only to TA, but it is not at all annoying. RnThe backlighting is, in my opinion, great. RnThe AF speed is really impressive (as in the first version, the rest), especially if you are using itThis optics with latest generation reflexes (7DII, 5DIII, 1DX and latest models). Even by mounting the new series III extender, the AF remains fast. Only with 2X III extender the slowdown is more apparent, but the speed remains, however, at very good levels. The latest generation stabilization allows you to shoot free-hand with unmanageable times for a 400 mm focal length. There are 3 stabilization modes, as well as all other Series II telephoto lenses. The price is high, but in line with the other "whites" and is positioned between the 300 f2.8 and the 500 f4 series II. In conclusion: if you have the clear ideas and are looking for a lightweight, versatile, portable, high quality telephoto lens, and you think the 400mm focal point is a good compromise, the 400 DO II has no rivals on the market. Detail in crop100%, if you want f2.8 because otherwise it's dark if you need 100mm more because otherwise you are coRti ,,,, in short, if you are undecided, maybe it is best to bet on the 300 f2.8 series II or 500 f4 series II.rn - PS: I come from a 500mm f4 IS USM (Series I) and I do not feel the lack ! |
