I shot an event for a cycling non-profit yesterday and overall was pleased with the lens. I found that I had to put the telephoto images into Photoshop and bump their brightness up +25-40 and reduce contrast -20 to match the photos taken without the lens. Outdoor event, ProPhoto app, iPhone XS. Lens sharpness good enough for their website and social media, not sure I'd make large prints - but these were moving objects and I moved the ISO from 25 to 100 in order to get a shutter speed that would stop the action. This step may be unnecessary for your projects.
I’m using it also in the wide angle camera. I made a vlog with it . https://www.instagram.com/tv/BxScwP1nqZB/?utm_source=ig_share_sheet&igshid=1ezk8epd2pytw I really like how you reach out to me with the email before it arrived. I can tell you all are a customer focused company with this email.
I am a creative amateur photographer. Have never owned a DSLR, but have always explored the available features on my point & shoot cameras, and have definitely spent too much time editing my images after the fact with various software/apps, so I thought I was ready for an add on lens. I underestimated the knowledge required to use the tele lens (and polarized filter). I was hoping the equipment would do all the work for me, but then professional photographers would be out of business. The first day I used the tele lens, I was disappointed with the images, BUT I forgot to touch my screen where I wanted the picture to focus, so it was user error. After that, the tele lens performed flawlessly! We visited Washington DC with a group, and I ended up with far superior photos than those who used just their iPhone or Samsung phone cameras. Truly the lens alone is deserving of a five star review, even if it takes a little effort to use properly. The reason I deducted one star is for the case design. I’ll admit I haven’t tried using the clip. I’m afraid I won’t get it perfectly centered on my phone. The aluminum housing around my phones lenses is intact, so I don’t know how the black plastic right above the aluminum cracked? I originally thought I ******* the lens in too tight, but I don’t think that could increase the pressure on that part of the case. There is a very narrow piece of plastic on the case above the aluminum that split in two on my case. It hasn’t affected the performance and the case still stays on my phone. I’m just afraid eventually the case will not hold to my phone, and I’ll have to use the clip. If the black plastic covered the entire top edge of the phone, it wouldn’t cover any buttons, and maybe that part would be stronger? Idk what happened to mine, it hasn’t been dropped, but for whatever reason it bothers me. Since the details matter, I’m giving the tele lens a four star rating. I am extremely happy with my purchase and love the pictures I now have because of this product. I would highly recommend the tele lens to a friend.
