I own both lenses and can confirm they are the same size to within 1/2mm

Hi, on an Android phone using Google's Gmail app, is there a quick/automatic way to compress .jpg files during the process of attaching them to an email? If not is there a workaround? Asking both ...

Thanks for sharing. I'm happy that I've saved several hundred pounds then :-D

Thank you. Will do in future - this is why I was asking. There doesn't seem to be a mention of this during the upload process.

No problem Ravee, I think you are absolutely correct. My misunderstanding stemmed from the fact that loading 'from gallery' or 'from computer' were presented as separate options. But I agree that ...

Ah OK, I stand (partially) corrected. But as others have said (further down) it doesn't tell you that it's adding it to your gallery at the time. The options for submission are "Load from your ...

Sorry but that behaviour appears to have changed. There is an 'upload from your computer' option which I used. I will compress any images in future, thank you.

Sorry if this has been asked before. I submitted a photo for a challenge for the first time yesterday. I uploaded my "keeper" image without applying any further compression, because I saw no ...

Placed 31^st in the challenge. Juvenile flamingo at a bird sanctuary is very tame.....but keeps a watchful eye for any approaching threat.

There are two settings on Canon cameras for flash. One is just called "On", the other "Slow syncro". When there is plenty of ambient light,  then there is no difference between these.  They behave ...

+1 for buying a second camera of the same model. I have two M5s. Zero learning curve. Same battery, which is more convenient and means you'll get a second charger that works with either camera. ...

Sorry if I am wrong but the sample you posted is a screenshot, and I'm wondering if that adds Moire because it will be a resampled image. So yes, you may see Moire on the screen (caused by the ...

Thanks very much for all the replies, I will try with a longer lens next time. In the meantime..... This is about the best from my set taken last week. This was taken with the same lens a few years ...

Hi, I'm not a beginner but.... I visited a garden last week and decided to challenge myself by taking only a 1:1 macro lens (also works as a standard 28mm lens for general snapshots). I don't get ...

I've sorted it. I already had a NEEWER neoprene case that came as part of a set of 4 I bought years ago. It was way too big for anything I had previously, so it was sitting in a box of stuff to go ...

Hi, any suggestions for a case for this lens with the Canon EF-M adaptor permanently mounted? I also will be keeping a UV filter on it. This brings the length to 232mm. I'd like something ...

I used my new Sigma 100-400mm this week at a local zoo. I left the OS switch permanently on, even though I turned the camera off and on several times during the day. I had no problems and neither ...

Thank you for the comments. I took the lens to a local zoo a few days ago. I didn't turn off OS at all. I didn't hear any chattering noises. I take on board what you say - that this might not be ...

Hi, I have just bought a Sigma 100-400mm Contemporary lens (Canon fit). Buried in the instructions it says never to turn the camera off whilst OS is switched on. Really??  How many other owners do ...

I have just bought a Sigma 100-400 C lens. I have had it just a few days so I haven't used it yet apart from a few test shots. The instructions are a bit contradictory about this. In one section ...
