    Features

    TheEF 17-40mm f/4L USM LensfromCanonis a high quality "L" series wide angle zoom lens for full frame and APS-C size DSLR cameras. It combines one high-precision molded glass asphericalelement and two replica aspherical lenses to achieve the extended zoom range, while also correcting for common aberrations that arise during zooming. A Super UD (Ultra-low Dispersion) glass element minimizes the chromatic aberration of magnification which tends to occur with wide-angle lenses, to help eliminate color bleed along the edges of the subject and achieve high image contrast and resolution.

    Thelens' minimum focusing distance is just 11" (28cm) throughout its entire range of focal lengths, which makes it very useful for close-up work. All of the focusing and zooming action is done internally, with no changesin the size of the lens. Its ultrasonic autofocus motor enables smooth and silent autofocus action and manual focus override in One Shot AF mode allows precise manual focusing without switching into MF mode.

    It only uses lead-free optics to help the environment, and features a circular diaphragm for improved background blur. The housing is water and dust resistant to help ensure reliable performance for both professionals and enthusiasts. Like many "L" lenses, it uses 77mm filters, but also has a rear gelatin filter slot behind the lens mount that can hold three gel filters.

    This lens is a Canon 'EF' series lens, indicating it is for use with full-frame cameras. However, it also works with APS-C format DSLRs and offersa 35mm focal length equivalence of 27-64mm, making it an ideal medium-aperture standard zoom lens.

    A super wide-angle zoom lens for full-frame DSLR and 35mm film cameras that offers a 27-64mm focal length equivalent when used on APS-c size sensors.
    Uses three aspherical lens elements and Canon Super UD ultra-low dispersion glass for reduced aberrations and overall sharp, high contrast imaging
    An ultrasonic autofocus motor provides fast, smooth and quiet AF action, particularly important when shooting video.
    Manual focus override enables precise manual focusing even when in One Shot AF mode.
    Internal zooming and focusing systems
    As a Canon "L" series lens it provides professional levels of moisture and dust resistance.
    Circular aperture diaphragm for better, more natural looking background blurring
    Accepts 77mm filters, as well as gelatin filters at the rear of the lens.

    What didn’t go wrong? I ordered a Panasonic 7,000 lumen projector from this vendor, paying an extra $144 for 2-day shipping. Chose them after exhaustive internet searching for the lowest price I could find (big mistake!). Two days later, I emailed and then called to let them know I did not receive my package and that the tracking number suggested that it had not yet been received by FedEx. The customer service person appeared helpful and offered to ship out a 5,000 lumen projector that we could use until they had my original order ready to ship. Of course they charged me the price for the 7K lumen projector when they shipped the smaller model. Long story short, after several months (July 2024 to December 2024) and many calls and promises to ship the product I ordered, I finally had enough and let them know I would be retuning the item they sent me and purchasing the projector I intended to buy from a more reputable company. It was no longer reasonable to expect my patience. They sent me a return label and appeared understanding. After shipping back their product and waiting two weeks, I called to inquire about the status of my refund (over $3,300). The customer service person stated that it would take up to two additional weeks to process. I have been waiting over two months for my money back and have formally filed a complaint with the State of New York against this business. I fear I will have to escalate legally if the state can’t help me successfully get my money back. Please beware! Use this company at your own risk, the “savings” they promise will not be worth it!

    Top-Tier. My new favorite shop for all things digital! They were available ASAP for me the night before a shoot and after a quick call, was able to connect with them and grab the perfect lens while other shops where closed. Highly recommend for all creatives and professionals.

    I purchased a DJI drone that said “NEW” on the add and was priced for $899. I payed an additional $24 for expedited FedEx shipping. 3 weeks later I recieved the package (by UPS ground not FedEx) to find not only was it a USED item (not in original packaging) but it was also a completely different item than what I purchased. I called customer service as soon as I made the discovery. I was told that they made a mistake and sent the wrong item. Ok…shit happens right. Then I was told they made a mistake on the price of the original item I purchased and that it would cost me $1100 to get the item I wanted and would take an additional 3-4 weeks to receive. I was also told the item I would get would be a USED item not the NEW item I had purchased. They did offer to discount the drone I received if I was willing to keep it instead of the one I wanted and ordered…um NO! (I have photo and written proof of all of this) I ended up returning the item and canceling my purchase. I decided to spend my $1100 with a reliable company for a NEW item that will be what I wanted and ordered. I will say the man on the phone was nice but everything he said had SCAM written all over. I pray I get my money back in a timely manner. If not it’s definitely going to be a report to the BBB! If you don’t want to wait weeks for what you hope to be the item you ordered then I would suggest you avoid this company. Not a pleasurable experience.

    Exactly what I wanted. I just bought my first precision cooker, so I’m super excited for not only the product, but the recipes.

    I purchased the Nikon Z6II through Walmart marketplace during Thanksgiving, and it was one of the best deals available. Initially, the delivery included the wrong lens, but the customer care team was exceptional in resolving the issue. They responded promptly and ensured I received the correct lens without delay. What impressed me the most was their proactive follow-up to confirm that the issue was resolved. The WhatsApp customer care service was also quick and efficient, making the entire process smooth and hassle-free. As for the camera itself, the Nikon Z6II is phenomenal—great image quality, fast autofocus, and perfect for both photography and videography. Overall, I’m delighted with the purchase experience with the seller and the product. Highly recommended to purchase from Buy and Direct.
