There the same lens with the name written differently. Most times this is a simple mistake when transcribing a name from the manufacturer. Lens names are complex and indeed look quite similar and honestly, Tokina has one of the more complicated schemes which they use inconsistently. As I have a site about digital cameras and lenses, Tokina sends me this ...

More blur == larger aperture, if other factors remain fixed. From 85cm you'll need a 35mm lens to get head & shoulders in shot, possibly a 50mm if you can drop the camera back a way. You can get a f/1.8 for a reasonable price or a f/1.4 for a lot more. $£€100 1.8 to $£€ 500 for a 1.4. The shorter your lens, the larger aperture you will need to blur the ...

I swapped the EF-S mount on the 10-18mm STM for a metal EF mount from Ebay. It took 5 minutes to unscrew the plastic EF-S and screw on the EF metal mount. You can then use it on the 6D, 6Dii, and 5Div - everything works with no crop. The image circle covers a FF sensor from 12mm-18mm, with good coverage for video from 14-18mm. I've read that the Tamron ...

The old grease will keep running into mechanism. The only way to eliminate the problem is to do a complete CLA. It needs to be flushed and cleaned of all grease, then properly relubed with new grease. Since it is a 200mm it has alot of grease in its long helicoid. If you are not comfortable with a complate disassembly then you should sell it for parts and ...

Just bought a pentax SF7 on eBay which came with a sigma 70-200 AF lens with the "sticky" plastic issue. I tried a few of the usual cleaning agents and found that the only thing that worked well was methylated spirits. I found that isopropyl alcohol didn't have much effect. Even with the methylated spirits it took a while to remove the gunge, and ...

"... if I remove the kit lens from my QX1 and press the shutter button, it does click and seems to take a picture." – Does the camera save an image to the memory card? If so, shouldn't that answer your question? You can try taking pictures with tape over the lens contacts If you capture anything recognizable, even if blurry, there's no reason you ...

I had a similar issue of a stuck DSLR lens as a result of the camera falling. It looked like the threads got misaligned preventing the zoom lens to turn. I have found a video on YouTube that was helpful to me since it showed how to "pop it back" into place. Not sure if helpful to others, but sharing in any cases: https://www.youtube.com/watch?v=...

I currently have the Tamron 70–200mm f/2.8 and it is a powerhouse of a lens that is very versatile. The f/2.8 will allow you to achieve a noticeably better bokeh than the f/4 and gives you the ability to lower your ISO in comparison to a f/4 or a f/5.6. It is a durable lens and in conjunction with a 1.4x or 2.0x teleconverter it will allow you to reach even ...
