    Well, you can’t read a blogpost while driving your car, but basically you’re right. I always wanted to listen how Roger sounds (great voice) but I’m not sure if I will keep up with the podcasts. As interesting as some of the guests are, as difficult it is to get sentences without big “uuuuhmmm” gaps, short and precise answers and illustrative descriptions. Some people use a lot of gestures while they’re talking, but in a podcast other rules apply.

    That was very interesting. Thank you for making this podcast.

    I don’t know if you had the questions prepared beforehand, but I’d definitely recommend you to do that if you haven’t – there were some long pauses in the audio that don’t really add anything, and unnecessarily lengthen the run time. It’d be ideal if you could keep the pace of the conversation a little more even all along the podcast, instead of starting very slowly and then rushing almost frantically at some points. I realize that these are skills that take years to develop, and they probably are outside of your realm of experience, though, while the content and delivery were quite good. So anyway, good job! I hope this podcast becomes a regular thing.

    I’m happy to see this launch! I listen to quite a few photography and lens-related podcasts, and I think this medium will be a natural fit for you Roger. I’m partway through the first episode and I’m enjoying the discussion. I do wish the sound levels were matched a little more closely between you and your guest.

  • Matthew Duclos is a great choice for your first guest! I’ve always thought you guys were kindred spirits in your optical interests.

  • Turniphead

    Given that your target market are photographers and videographers (visual people), why have you chosen an entirely non-visual method of communication here i.e. Podcasts? Please can you at least post the full transcripts? I can read it in a matter of minutes, but listening will take nearly an hour, and if I’m honest I gave up after 2 mins… I read all Roger’s geek articles with great interest, but this just leaves me cold. Sorry!
