I have the Sigma AF 400mm AF Tele Macro HSM and if I use it with a 5 element 1.4x teleconverter, I get a 560mm f/8 equivalent that is still very sharp. That is good enough for me.

So, camera makers got rid of the mirror and shortened the lens to sensor distance to make the camera more compact, and then they put that massive hand grip in to make the camera easier to hold. So,...

These Sony cameras remind me of the Origami styling seen in Japanese cars in the 1970s such as the Toyota Celica, with distinct straight lines and sharp corners.

The 12 mp FF sensor lives on.

The reason fast lenses are expensive is because ashperical lens elements are needed to correct for spherical aberration. Ashperical elements are expensive to produce. Anyone can make a profit...

It was evident that film cameras were doomed early in the 21st century. People were taking pictures with fixed lens digital cameras with tiny sensors instead of their SLR film cameras. Film camera...

Ricoh has been successful in non-camera businesses, and so was Konica. Konica got out of the camera business, then it bought Minolta and later sold Minolta;s camera business to Sony. Yashica was...

Film camera prices are so low that a collector can buy a Nikon F4, a professional model with interchangeable prisms and autofocus for less than a couple of Benjamin Franklins. When new, the Olympus...

I remember an article by Herbert Keppler way back in the 1980s IIRC, in which he asked photographers to look at photos taken by an Olympus OM series camera and others taken with Nikon cameras and...

Olympus' had a broken crystal ball. It did not anticipate a future in which FF sensors are cheap enough to make that many amateurs can afford to buy them. I would be suprised if the firm that buys...

Olympus' sale has nothing to do with smartphones. They were already in trouble quite a few years back and Sony saved them by investing a lot of money in Olympus. Smartphones pretty much made fixed...

I wonder how this camera stacks up against the Nikon D750 in terms of price and performance. The D750 has an in camera focus motor and the F mount, so it can use a wide selection of lenses. Other...

I shoot with both eyes open anyway, regardless of camera brand (I do use a few brands, Pentax, Nikon, Canon and Sony but no Olympus) because I find it more comfortable than to shut one eye by ...

I still remember those Olympus OM series SLR cameras and the camera tests that showed the 1/1000 sec. shutter speed is wildly optimistic. I also thought they were overpriced. My first camera was a...

The main attraction of the M43 format is compactness. MIrrorless models from Canon and Sony as well as other camera makers with larger sensors are just as compact and they sell for less money. It...

He is correct. Olympus cameras have a loyal following. The world is moving to full frame and yet Olympus can still hang on with its micro 4/3 format. A person would have to be loyal to pay more...

I do not own any mirrorless bodies. They promise compactness but they cannot deliver because what they remove from the body has to be added to the lens. Even a total redesign of the lenses won't...

When you shoot movies, the shutter is always open and the mirror is always up. The only way to control exposure is to vary the aperture. Aperture priority would mean that the camera cannot vary ...

Digital IS better. Nevertheless there are still people who argue that they like the "warmer" sound of the analog LP, and that the CD is "antiseptic," meaning they actually prefer to hear the clicks...

Full frame is less demanding on lenses than APS-C. Any lens that works well on the APS-C camera and can cover the full image circle of a full frame camera will work well on a FF camera. Some ...
