Those intermediate apertures are actually really, really good. Usually a lens like this would drop to f3.5 at ~40mm, to f4.5 at ~70mm and be f5.6 from -100mm.

It's very interesting to compare this...

I don't own any of the most recent focus-by-wire lenses, but my experience with those that I have has not been positive. For example, my 55-250mm STM (released in 2013) has much slower, less crisp...

Tamron's DSLR 24-70mm f2.8 G2 lens was released for 1200 USD. The mirrorless smaller zoom ratio 28-75mm f2.8 was released for 800 USD. A full 400 USD/33% less.

ImCat: Light-gathering, i.e. total amount of light gathered, which determines noise level in the image, *is* affected by equivalence. Your misunderstanding maybe comes from the fact that...

He is 100% right in comparing the fixed-lens camera with an ILC+lens. Why shouldn't he? The Canon M50 + 22mm f2 has the same focal length and aperture, is the same weight, and is only slightly...

Also judging from the photo the surface that the camera focuses on sits a little bit in front of the 0mm position, roughly around the 1.5-2mm mark. So this is maybe a 1-1.5mm front focus which is...

Then the lens would have been larger, heavier and more expensive. Telephoto zooms are generally much more limited by the longest focal length (and aperture at longest focal length) than by zoom ratio.

It's interesting how differently Canon and Nikon are doing the FF/APS-C split. We need to remember that the only reason APS-C became so common in the first place is that it was hard to make large...

Having a small number of lenses that take full advantage of a smaller sensor (like the 11-22mm, 22mm f2, and 32mm f1.4) is FAR preferable to having a large number of unoptimized lenses.

There is...

This camera is insane. Personally I wouldn't use a Chinese smartphone, but I would want that camera in my phone. The crop factor compared to 1" cameras is only 1.3. It's as close to high-end...

The market is shrinking, so manufacturers seem to be responding by hiking prices. Only time will tell how this pans out for them.

Moreover it's even greater for third-party lens users. For example there is *nothing* that even comes close to the price-performance ratio of a recent Sony A7-series camera + the Tamron 28-75mm f2.8.

20-50mm (FF equivalent) really is a mold-breaker. I'm sure it suits a lot of people better than 16-35mm or 24-70mm. And for such a small sensor the equivalent aperture isn't bad at all. It's like...

To the people saying this lens might be expensive because of optical performance: this article says "Sigma claims that it has been designed to give very pleasant bokeh, transitioning from a...

The 560 USD price is pretty remarkable (although not in a good way).

I of course agree that a 5D camera with the 40mm f2.8 isn't a compact imaging system. But the lens in and of itself is a pancake. And there are plenty of mirrorless pancake lenses, the...

A 35mm lens has a 10mm shorter focal length than a 45mm lens, which implies it can be approximately 10mm shorter assuming neither lens uses a telephoto or retrofocus design. This lens is 46mm long...

Citation: The fact that a lens that focuses an image 45mm away from it's rear nodal point can't have the rear of its construction anywhere near 18mm away from the imaging sensor unless it's a...
