Well yes, for your m43 these Canon lenses would be quite unsuitable.

Joiarty I am not talking about the best way to photograph sport. I am talking about what a security guard will let in through the door.

No they don't. They go with whatever it says on a lens. So I have had no problems with a 200mm on APSC. And ironically, have been fine shooting a Sigma 70-200mm f/2.8 lens on a DSLR, but been stopped with a much smaller (and less professional-looking) NEX-6 and 55-210mm combo.

But I'm sure that if your super-zoom is labelled 24-600mm or similar then I'm sure that they'd call that a 600mm even though the physical focal length is much shorter.

I doubt that they'd know what a teleconverter is and since I don't have one I probably won't ever find out.

A 210 mm lens is incredibly frustrating, because a lot of sporting venues impose a 200 mm focal length cap on what you can bring in. That is certainly my experience with Australian sporting venues, whether that is for the football, cricket or soccer. And yes, I was prevented from using an E-mount 55-210 mm lens a few years back on a NEX-6. 10 mm extra isn't a lot of extra reach for all of the hassle that it brings.

I think rbach44 was being sarcastic there visualenvy.

An 18-135 mm is a great travel and walk-around lens option. I used one on my Pentax DSLRs for a while. But ironically given Visualenvy's comment, I have just swapped it for the Pentax 16-85 mm. While it has a little less reach, the 2 mm extra wide angle is worth it.

Are public transport buildings such as train stations permitted as the main subject of the photo? Or does the main subject need to be a public transport vehicle?

No need. hey already have the 150-450mm.

From the rules, we can assume that black and white, which are strictly speaking not colours, will be treated as if they were colours?

That is just gorgeous. The layers of the dark water, the light reeds, the dark trees, etc. The tranquility of the scene. The lone guy in his canoe silhouetted against the light background.

Come on, since when can't we just write heck? The whole idea is that it's a euphamism for hell. We're not 5 years old.

Except there is also the crowd that will buy an enthusiast DSLR and just leave it on auto, and then wonder why their photos are hardly any better than before. This might suit them just fine.

A FF lens will work fine on a crop sensor. It's the other way around that problems arise.

It shows that taking the picture is half of it. Knowing how to present that picture for maximum impact, which in this case means a great tight crop, is the other half of it and one that has given your picture enormous impact.

A great action shot and a beautiful tight crop.

This is a beautiful picture but while I assume that the river curves around to the right in the distance it is not really visible.

Great to see such a good looking German Shorthaired Pointer star in a review.

I actually really like the composition of this shot, but the processing of it was not to my taste with those nasty halos.

How is that relevant to a PEN-F review, which has a different sensor?

The Pana is 10mm longer and has a faster aperture at the long end: f/5.6 vs 6.3. But that's not intended to take away from the valid points that daddyo and MikeFL have made. I suppose it's a matter of weighing up what's more important to you.
