My Sigma PG-21 grip is not behaving as it should on my SD15 camera. Put two freshly charged batteries in and it reads full. When the batteries lose some charge the indicator can show very low or empty. Take out one battery, turn the camera on and the indicator shows full. I have noted similar behaviour with the PG-31 on my SD1 Merrill. The PG-21 and PG-31 are essentially the same grip with I'm sure the same internal make up. Would anyone here know why they behave in this way.? The cameras are...

Hi there Sigmarians! At least one of my SD9, and one of my SD10, and a DP1x, they all lose time and date immedeately after removing the main battery. (To be precise the affected SD9 does so when changing the CR123s).  A well prepared and very quick and hasty (main) battery exchange in say 5 seconds does not help. It's already too late then. Time and date info lost.  So I suppose, all those cameras do not have a built in buffer capacity, which should recharge from the main battery, but rather...

Would anyone know why, with two batteries in the PG-21 or PG-31 battery grips on the SD15 & SD1M, the cameras indicate empty even when both batteries show at 40% in my battery charger. Also I discovered recently that if one battery is removed from the Grips  the power indicator then shows correctly on the cameras and they can then be used until the one battery goes dead and the same for the second battery with only that one in the grip. I presume it is caused by some "fault" in the grips...

Both camera has a unique sensor(Super CCD, Foveon) and I want to try it out. I tried to search the comparison, but almost nobody mentioned on how it does on wildlife photography. What I  found is that both camera won't do good on low light. However, bird photography usually takes place under bright daylight so it won't be a problem. Which one will do the best on bird photography?

Hello My yesterdays shoots showed some dark spots which shouldn't be there.  What's the reason of this flaw and how to fix it ? I'm using the Sigma SD15 camera + Sigma 17-200mm f3.5 6.3 DC. It was purchased second hand and as a previous model it is out of guarantee.

Hi, I am considering buying a Sigma FP but I am torn between this and a Sigma Quattro H. I have an SD15 and the 18-35 F1.8 Art and the 50-100 F1.8 Art. These I understand would be fine on the Quattro. However I go down the FP road and use the MC-21, will I get vignetting or experience cropping of the FP sensor given my lenses are APSC? I can't really justify the expense of buying new L Mount lenses at this time. My thanks in anticipation  George

With the advent of Analog Front Ends on Sigma cameras with the consequent danger of blown highlights, even at high ISO settings compared to earlier models, what is your normal method? This question is more about such as DP2x, SD15, Quattro but I'm interested in any Foveon-equipped model. It is also about single-shot photography: not stacking and not SFD - trying to keep to basics ... Personally, I spot-meter the area of interest in the scene and make my best guess at the necessary exposure...
