On Sony SLT-A77 II First Impressions Review preview (599 comments in total)
In reply to:

Vitruvius: Top of page 4 - the SLT mirror does NOT redirect 1/3 of the light. It is about 1/3 of a stop of light.

Interesting that they would NOT have included the on-sensor phase detect AF from the a6000 in this camera in addition to the SLT AF sensors. I have about 7000+ actuation shooting action with my A77 and the AF tracking is actually very poor even with fast lenses and SSM / HSM.The only reason I would have spent an extra $400 on the new A77ii was for the same AF system as the a6000. I wonder why they would not have included this on the A77ii? If it is the same sensor why can't they combine the information from both AF systems? But I guess we will have to see how they compare.

AFAIK 1/3 of a stop means 1/3 of the light.

In reply to:

nickwit: Can somebody please tell me how the extra sensor size affects aperture, i.e. what the equivalent f stop is on a ff.
Thank you

In terms of light gathering it is essentially the same. In terms of depth of field relative to the full image captured, approximately (note that there is an aspect ratio difference) a 0.79x ratio applies, i.e. for the same focal length and focusing distance to get the equivalent DOF effect of a f/2.8 on a 135 camera you'll need a f/3.5 lens on a medium format camera with a sensor like the one on the Pentax 645z.

On Ricoh announces HD Pentax DA AF 1.4X AW rear converter article (52 comments in total)
In reply to:

Anastigmat: The Kenko Pro 300 1.4x and Sigma APO 1.4x teleconverters both have 5 elements. This Pemtax has only 4 elements. Even though more isn't necessarily better, you have to wonder how well it performs against the Kenko Pro, which is unfortunately not available in Pentax mount. This teleconverter is also designated a DA, not a DA*, for what it is worth, but its pricing is more DA* than DA.

Never in the history of Pentax any converter was given a * to its name. That is a designation for lenses only.

I've just begun waiting for the Chinese version of the film duplicator

This should be constant f/1.2, weigh less than 0.5kg, built of titanium and I will buy it if it is not over 200 rupees.

In reply to:

Thoughts: Pentax users , although much fewer, tend to be more informed about their gear, which is quite good value for money.

I have never used Pentax DSLR, but I do love their small prime lenses. Nikon isn't very keen to offer similar DX lenses (35mm, 40mm, anything else I miss?), which was one of the main reasons why I decided to leave Nikon camp- I don't think I want to upgrade my DX to FX with everything heavier...

Well done, Pentax (and Sony) this year. I think the day when the industry without these two companies would be really a bad day for everyone...

In reply to:

Timmbits: I don't mean to badmouth pentax or anything of the sort, but with new FF mirrorless models being introduced by Sony, and others to follow... although a good idea, the selectable olpf sounds like the sort of innovation I'd fall for when I was younger, but which seems moot, when you consider that more of us have started to ponder graduating to FF and have been eagerly waiting to see what develops in FF.
At end of 2013, I'm definitely not willing to pay entry-level FF prices for an APSC, no matter what bells and whistles they throw into it.

Which FF camera can you buy for $1,299?

In reply to:

Pablom: So all the fuss is about AF speed in live view? who cares about that? I'd assume probably Rebel owners rather than the target market for this camera.

yabokkie, I don't see the day when optical viewfinders disappear. Call me old fashioned but I'd prefer tracking the scene directly with my own eyes with the camera steady and firm as an extension of my body rather than viewing through an electronic screen and holding the camera clumsily as if it were a baby with a dirty diaper.
The only benefit I currently see about live view is for use on a tripod and for fine manual focusing, which is what I use it for.

This is roughly the same size as my 3 year old Pentax K-x with a 40 year old K mount.
I don't see an engineering achievement here.

In reply to:

jon404: Pentax people -- if I got a K-30, does Pentax make a 35mm or 40mm small, bright, sharp prime lens that you would recommend? I hate zooms.

You'll love it

In reply to:

JackM: I wish that 40mm f/2.8 kit pancake with the K-01 was a 32mm f/1.4 or f/2.

I doubt they can make one of those very slim
