Danubia 90-210mm f/4 MC Auto

Still Canon's Best Versatile Zoom! Still Canon's best versatile zoom! Despite the less-than-glowing official reviews, this new 24-105 is a worthy purchase. I've owned the Mark I version three times, the 24-70 f/2.8 II, and the 24-70 f/4. My major disappointment with the f/2.8 II was lack of IS. Halloween and Christmas pics were next to impossible to get without toting a tripod around. The f/4 was very nice since it had IS, but I still missed that 105mm! I just recently purchased the Tamron 24-70 G2, which is a fantastic lens (f/2.8 and Vibration Compensation), but guess what...I missed that 105mm! So, decided to buy this lens, and after a little bit of AFMA, the lens is superb! Quick focusing, sharp images (much improved in corners), and lets in more light than the previous version. No, it doesn't have 2.8, but the IS is better than the first version, so that helps tremendously with slow moving subjects. You can shoot everything from wide landscapes to head and should portraits with nice bokeh. Yes, you lose some quality when compared to the 24-70s, but that is pure physics. This is the best compromise between image quality and focal range in my experience.Read full review

Pricey but worth it. I have been using this lense for a few months now and have been very happy with the results using my 5d mark iv. Its not heavy or bulky but you can feel the quality in its built. Images come out great. It is an awesome walk around lense and portrait lense. I utilize the 24 105 L ll as an intermediate photographer and I can wield it to my liking using various camera settings to capture my subjects. Get this lense..you wont be disappointed.

Great Lens but Do You Need It? Pros: very good build quality, weather sealing, lens sharpness and contrast Cons: for some this lens can be seen as being heavy, but I am ok with that since most of my work involves a camera mounted on a studio stand or tripod. One note: the sharpness and contrast of this L lens may not be that much greater than some of Canon's newest non L lens to justify the price differential so if you do not need the weather seals and the extra durability, the extra cost vs. A newer non L lens may not be worth it for the bump in sharpness and contrast for some photographers.
