Comment by Daniel Bridge posted on K5 - Exposure bracketing with contant aperture...again at 09/06/2013 - 00:25
I bought an 86mm CPL filter for my Sigma 50-500, just one from eBay, not the cheapest but relatively cheap, and that was quite poor in how it screwed on to the lens. When I tried it at the weekend I also found that it affected focus quite badly, whether that was because it's rubbish, or because it wasn't on properly, or some other reason, I don't know.
Any thoughts on why it affected focus so much?

Thanks for posting, though you're right about the price as I'd be inclined to stretch the extra mile and get a brand new lens if that's the best I could get 2nd hand.

Ah, here it is. Might be more than you were thinking on spending though.

And I whole-heartedly agree with your second paragraph.

Must admit that I find Live View extremely useful and use it often, great for taking long exposure photos of waterfalls/flowing water
As far as the original post is concerned, I can't say I've ever thought the screen particularly dim, and the bottom section of the screen is used for shooting info simply because the screen is a different aspect ratio to the image, and this bit would otherwise be wasted. It's not hiding a bit of the image, it's just blank area, very handy for putting info in.

Answered your poll...I put No, mainly because I offer them and think my prices are very reasonable

There is no reason not to build a FF exactly the size of a K5. All it requires is a larger mirror and a larger focusing screen in front of a FF sensor.

For example, the crop factor means APS-C is better than FF for sports and nature shots. Our long lenses are even longer and if that's what we want, then APS-C is better
Well john, I am not sure if you know, how it works:
The crop factor of APS to FF is 1.5. So your 300mm lens looks like a 450mm lens. However it is still a 300mm lens if you consider the FF Size.
You apparently get a more telephoto with APS, but only because you look at a part of the image the lens can produce. Assuming your FF Pixel count is 1.5 times The APS count which may be 16Mp. This the works out to 24Mp.
If you now take a shot with a FF sensor, you still have all the information on the image the APS sensor gave you, plus some extra.
Now if you crop the FF image by the factor of 1.5, You arrive at the same Image and the same quality as if you mounted the 300mm lens on to an APS camera.
