Was your purchase recent? You should return the Sigma 100-300 f4. Most are very sharp - on par with 300 prime, and good AF by itself (no good with 1.4x)
Only poor performance in close at MFD - soft...

The advantage of the 1 system is redundancy. If you have an interchangeable system, and one component breaks or breaks down, you can mix and match and keep shooting.
If you have two or three fixed...

Does it bode well for a new V-camera? Either Nikon keep changing their minds, or they have a grand plan that includes everything, well integrated, eventually.
So now that they've done the research...

Like the D400 never was. History shows that Nikon got their priorities very wrong there! But on with Pentax...

It's all about quality, and if you want high optical quality at bargain prices, and don't mind forgoing some mechanical wizardry, going old high-quality is still a viable option.

Example wildlife...

High-end lenses of today are better than high end lenses of yesteryear, and low-end lenses of today are better than my first Domiplan, for sure. But it's all about quality.
My 250mm Sonnar of 1978...

I’ve used the Nikkor 300mm f2.8 AF-D, 28-105 macro and Canon 100-400 version 1 professionally for nature photography, the Nikkors on a D7100 in crop mode which is similar to M4/3. I think you ...

Thanks Richard. I didn't like to be tedious, but that sounds about right.
At least, I'd suggest that dpReview publishes a picture of the K1 beside a Pentax 6x7, because while it uses the 35mm...

I use 18mm, 25mm and 35mm CY Distagons on a Canon 5D2.
Could you elaborate on what you mean? Am I better off with the Pentax body?

I agree but it begs a question I often have - who are all these great cameras for? If you were starting out from scratch, it would be the result of some terrible disaster in which you lost all your...

As a Pentax 6x7 stock shooter in the halcyon days of stock, this camera has a lot of appeal.

I know dpReview isn't into retro, but it would be a very readable piece if dpReview could get a hold of...

Many thanks for these enlightening answers. I see what the problem is with the limited focus range of the lens, but I think it would be enough for my field use. I don't think I have the nerve to ...

Thank you for your replies - both you and Bob are getting amazing quality from this little camera. Well done and thanks for sharing!

Sorry if this has been covered but I did an unsuccessful search. Is anyone getting good macros from this feature? I read that the Olympus Tough TG-3 and 4,  the OM EM1, and maybe some Hasselblads ...

Hi Stemu, This is higher IQ than I've been able to achieve with the V1. Would you mind elaborating on your workflow? How the camera is set up and what you do in post. Is it a straight raw process ...

Is the world's climate getting warmer from human activities? Not according to the deniers. Is the world round? Not according to the deniers. Can we do anything about the noise in the FZ1000? Well ...

Good on you, JP. I think there are a lot of other photographers with your line of thinking, hence the popularity of this thread (and the investment Oly have made in this lens). I use the 120-300 ...

Don't forget Oly's own 600mm f6.5. Nikon and Canon cater for the long slow teles with their teleconverters, eg a 300mm f4 with 2x tc, which would still be better than those cheap ones like the 650 ...

The attached image was made last Sunday with much less expensive gear than Oly's, but it's an example of a 1980's lens, and action subjects irrelevant to image stabilisation (I know you have some ...
